Constructor & Destructor Documentation

XercesDocumentBridge::XercesDocumentBridge ( const DOM_Document_Type & theXercesDocument,
bool threadSafe = true,
bool buildBridge = true )
 

Constructor for XercesDocumentBridge.

If the document will be shared amongst multiple threads of execution, the parameter buildBridge must be true. Otherwise, the bridge nodes will be built on demand, a process which is not synchronized. This could cause serious problems if multiple threads tried to visit an unbuilt node at the same time.

Parameters:
theXercesDocument   The Xerces document to bridge
threadSafe   If true, the tree can safely be shared amongst multiple threads. (Also implies buildBridge == true)
buildBridge   If true, all of the bridge nodes will be built during construction.

Member Function Documentation

XalanNode * XercesDocumentBridge::appendChild ( XalanNode * newChild ) [virtual]
 

Adds the node newChild to the end of the list of children of this node.

If the newChild is already in the tree, it is first removed.

Parameters:
newChild   The node to add.If it is a DocumentFragment object, the entire contents of the document fragment are moved into the child list of this node
Returns:
The node added.

Reimplemented from XalanDocument.

void XercesDocumentBridge::buildBridgeNodes ( )
 

Build the entire bridge structure.

This should be done before any processing begins, if the tree will be shared amongst multiple threads.

XercesDocumentBridge * XercesDocumentBridge::cloneNode ( bool deep ) const [virtual]
 

Returns a duplicate of this node.

This function serves as a generic copy constructor for nodes.

The duplicate node has no parent ( parentNode returns null.).
Cloning an Element copies all attributes and their values, including those generated by the XML processor to represent defaulted attributes, but this method does not copy any text it contains unless it is a deep clone, since the text is contained in a child Text node. Cloning any other type of node simply returns a copy of this node.

Parameters:
deep   If true, recursively clone the subtree under the specified node; if false, clone only the node itself (and its attributes, if it is an Element).
Returns:
The duplicate node.

Reimplemented from XalanDocument.

XalanAttr * XercesDocumentBridge::createAttribute ( const XalanDOMString & name ) [virtual]
 

Creates an Attr of the given name.

Note that the Attr instance can then be attached to an Element using the DOMElement::setAttribute() method.

Parameters:
name   The name of the attribute.
Returns:
A new Attr object with the nodeName attribute set to name, and localName, prefix, and namespaceURI set to null.
Exceptions:
DOMException   INVALID_CHARACTER_ERR: Raised if the specified name contains an illegal character.

Reimplemented from XalanDocument.

XalanAttr * XercesDocumentBridge::createAttributeNS ( const XalanDOMString & namespaceURI,
const XalanDOMString & qualifiedName ) [virtual]
 

Creates an attribute of the given qualified name and namespace URI.

"Experimental - subject to change"

Parameters:
namespaceURI   The namespace URI of the attribute to create.
qualifiedName   The qualified name of the attribute to instantiate.
Returns:
A new Attr object.
Exceptions:
DOMException   INVALID_CHARACTER_ERR: Raised if the specified qualified name contains an illegal character.
NAMESPACE_ERR: Raised if the qualifiedName is malformed, if the qualifiedName has a prefix and the namespaceURI is null or an empty string, if the qualifiedName has a prefix that is "xml" and the namespaceURI is different from "http://www.w3.org/XML/1998/namespace", if the qualifiedName has a prefix that is "xmlns" and the namespaceURI is different from "http://www.w3.org/2000/xmlns/", or if the qualifiedName is "xmlns" and the namespaceURI is different from "http://www.w3.org/2000/xmlns/".

Reimplemented from XalanDocument.

Parameters:
data   The data for the CDATASection contents.
Returns:
A CDATASection object.
Exceptions:
DOMException   NOT_SUPPORTED_ERR: Raised if this document is an HTML document.

Reimplemented from XalanDocument.

A DocumentFragment that references the newly created document fragment.

Reimplemented from XalanDocument.

XalanElement * XercesDocumentBridge::createElement ( const XalanDOMString & tagName ) [virtual]
 

Creates an element of the type specified.

Note that the instance returned implements the Element interface, so attributes can be specified directly on the returned object.

Parameters:
tagName   The name of the element type to instantiate.

A Element that reference the new element.

Reimplemented from XalanDocument.

XalanElement * XercesDocumentBridge::createElementNS ( const XalanDOMString & namespaceURI,

Reimplemented from XalanDocument.

XalanText * XercesDocumentBridge::createTextNode ( const XalanDOMString & data ) [virtual]
 

Creates a Text node given the specified string.

Parameters:
data   The data for the node.
Returns:
A Text object that references the newly created text node.

Reimplemented from XalanDocument.

void XercesDocumentBridge::destroyBridge ( )
 

Destroy the entire bridge structure that connects the Xerces document to this XercesDocumentBridge instance.

This will invalidate any pointers to any nodes in the document (except, of course, the document itself).

const XalanNamedNodeMap * XercesDocumentBridge::getAttributes ( ) const [virtual]
 

Gets a NamedNodeMap containing the attributes of this node (if it is an Element) or null otherwise.

Reimplemented from XalanDocument.

const XalanNodeList * XercesDocumentBridge::getChildNodes ( ) const [virtual]
 

Gets a NodeList that contains all children of this node.

If there are no children, this is a NodeList containing no nodes. The content of the returned NodeList is "live" in the sense that, for instance, changes to the children of the node object that it was created from are immediately reflected in the nodes returned by the NodeList accessors; it is not a static snapshot of the content of the node. This is true for every NodeList, including the ones returned by the getElementsByTagName method.

Reimplemented from XalanDocument.

XalanDocumentType * XercesDocumentBridge::getDoctype ( ) const [virtual]
 

Get Document Type Declaration (see DocumentType) associated with this document.

For documents without a document type declaration this returns null reference object. The DOM Level 1 does not support editing the Document Type Declaration, therefore docType cannot be altered in any way.

Reimplemented from XalanDocument.

XalanElement * XercesDocumentBridge::getDocumentElement ( ) const [virtual]
 

Return a reference to the root element of the document.

Reimplemented from XalanDocument.

XalanElement * XercesDocumentBridge::getElementById ( const XalanDOMString & elementId ) const [virtual]
 

Returns the Element whose ID is given by elementId.

If no such element exists, returns null. Behavior is not defined if more than one element has this ID.

Note: The DOM implementation must have information that says which attributes are of type ID. Attributes with the name "ID" are not of type ID unless so defined. Implementations that do not know whether attributes are of type ID or not are expected to return null.

"Experimental - subject to change"

Parameters:
elementId   The unique id value for an element.
Returns:
The matching element.

Reimplemented from XalanDocument.

XalanNodeList * XercesDocumentBridge::getElementsByTagName ( const XalanDOMString & tagname ) const [virtual]
 

Returns a NodeList of all the elements with a given tag name.

The returned node list is "live", in that changes to the document tree made after a nodelist was initially returned will be immediately reflected in the node list.

The elements in the node list are ordered in the same order in which they would be encountered in a preorder traversal of the Document tree.

Parameters:
tagname   The name of the tag to match on. The special value "*" matches all tags.
Returns:
A reference to a NodeList containing all the matched Elements.

Reimplemented from XalanDocument.

XalanNodeList * XercesDocumentBridge::getElementsByTagNameNS ( const XalanDOMString & namespaceURI,
const XalanDOMString & localName ) const [virtual]
 

Returns a NodeList of all the Elements with a given local name and namespace URI in the order in which they would be encountered in a preorder traversal of the Document tree.

"Experimental - subject to change"

Parameters:
namespaceURI   The namespace URI of the elements to match on. The special value "*" matches all namespaces.
localName   The local name of the elements to match on. The special value "*" matches all local names.
Returns:
A new NodeList object containing all the matched Elements.

Reimplemented from XalanDocument.

XalanNode * XercesDocumentBridge::getFirstChild ( ) const [virtual]
 

Gets the first child of this node.

If there is no such node, this returns null.

Reimplemented from XalanDocument.

XalanDOMImplementation * XercesDocumentBridge::getImplementation ( ) const [virtual]
 

Return the DOMImplementation object that handles this document.

Reimplemented from XalanDocument.

IndexType XercesDocumentBridge::getIndex ( ) const [virtual]
 

Get the node's index.

Valid only if isIndexed() reports that the document is node-order indexed.

Returns:
The index value, or 0 if the node is not indexed.

Reimplemented from XalanDocument.

XalanNode * XercesDocumentBridge::getLastChild ( ) const [virtual]
 

Gets the last child of this node.

If there is no such node, this returns null.

Reimplemented from XalanDocument.

const XalanDOMString & XercesDocumentBridge::getLocalName ( ) const [virtual]
 

Returns the local part of the qualified name of this node.

For nodes created with a DOM Level 1 method, such as createElement from the Document interface, it is null.

Reimplemented from XalanDocument.

const XalanDOMString & XercesDocumentBridge::getNamespaceURI ( ) const [virtual]
 

Get the namespace URI of this node, or null if it is unspecified.

This is not a computed value that is the result of a namespace lookup based on an examination of the namespace declarations in scope. It is merely the namespace URI given at creation time.

For nodes of any type other than ELEMENT_NODE and ATTRIBUTE_NODE and nodes created with a DOM Level 1 method, such as createElement from the Document interface, this is always null.

Reimplemented from XalanDocument.

XalanNode * XercesDocumentBridge::getNextSibling ( ) const [virtual]
 

Gets the node immediately following this node.

If there is no such node, this returns null.

Reimplemented from XalanDocument.

const XalanDOMString & XercesDocumentBridge::getNodeName ( ) const [virtual]
 

Reimplemented from XalanDocument.

NodeType XercesDocumentBridge::getNodeType ( ) const [virtual]
 

An enum value representing the type of the underlying object.

Reimplemented from XalanDocument.

const XalanDOMString & XercesDocumentBridge::getNodeValue ( ) const [virtual]
 

Gets the value of this node, depending on its type.

Reimplemented from XalanDocument.

XalanDocument * XercesDocumentBridge::getOwnerDocument ( ) const [virtual]
 

Gets the Document object associated with this node.

This is also the Document object used to create new nodes. When this node is a Document or a DocumentType which is not used with any Document yet, this is null.

Reimplemented from XalanDocument.

XalanNode * XercesDocumentBridge::getParentNode ( ) const [virtual]
 

Gets the parent of this node.

All nodes, except Document, DocumentFragment, and Attr may have a parent. However, if a node has just been created and not yet added to the tree, or if it has been removed from the tree, a null Node is returned.

Reimplemented from XalanDocument.

const XalanDOMString & XercesDocumentBridge::getPooledString ( const XalanDOMChar * theString,
XalanDOMString::size_type theLength ) const
 

Get a pooled string.

If the string is not in the pool, add it.

Parameters:
theString   The string to pool.
theLength   The length of the string. If XalanDOMString::npos, the string is assumed to be null-terminated.
Returns:
A const reference to the pooled string.

const XalanDOMString & XercesDocumentBridge::getPooledString ( const XalanDOMString & theString ) const
 

Get a pooled string.

If the string is not in the pool, add it.

Parameters:
theString   The string to pool.
Returns:
A const reference to the pooled string.

const XalanDOMString & XercesDocumentBridge::getPrefix ( ) const [virtual]
 

Get the namespace prefix of this node, or null if it is unspecified.

Reimplemented from XalanDocument.

XalanNode * XercesDocumentBridge::getPreviousSibling ( ) const [virtual]
 

Gets the node immediately preceding this node.

If there is no such node, this returns null.

Reimplemented from XalanDocument.

DOM_Document_Type XercesDocumentBridge::getXercesDocument ( ) const
 

Get the Xerces DOM_Document that this XercesDocument represents.

Returns:
the Xerces DOM_Document instance.

bool XercesDocumentBridge::hasChildNodes ( ) const [virtual]
 

This is a convenience method to allow easy determination of whether a node has any children.

Returns:
true if the node has any children, false if the node has no children.

Reimplemented from XalanDocument.

XalanNode * XercesDocumentBridge::importNode ( XalanNode * importedNode,
bool deep ) [virtual]
 

Imports a node from another document to this document.

The returned node has no parent (parentNode is null). The source node is not altered or removed from the original document; this method creates a new copy of the source node.
For all nodes, importing a node creates a node object owned by the importing document, with attribute values identical to the source node's nodeName and nodeType, plus the attributes related to namespaces (prefix and namespaces URI).

"Experimental - subject to change"

Parameters:
importedNode   The node to import.
deep   If true, recursively import the subtree under the specified node; if false, import only the node itself, as explained above. This does not apply to Attr, EntityReference, and Notation nodes.
Returns:
The imported node that belongs to this Document.
Exceptions:
DOMException   NOT_SUPPORTED_ERR: Raised if the type of node being imported is not supported.

Reimplemented from XalanDocument.

XalanNode * XercesDocumentBridge::insertBefore ( XalanNode * newChild,
XalanNode * refChild ) [virtual]
 

Inserts the node newChild before the existing child node refChild.

If refChild is null, insert newChild at the end of the list of children.
If newChild is a DocumentFragment object, all of its children are inserted, in the same order, before refChild. If the newChild is already in the tree, it is first removed. Note that a Node that has never been assigned to refer to an actual node is == null.

Parameters:
newChild   The node to insert.
refChild   The reference node, i.e., the node before which the new node must be inserted.
Returns:
The node being inserted.

Reimplemented from XalanDocument.

bool XercesDocumentBridge::isIndexed ( ) const [virtual]
 

Determine if the document is node-order indexed.

Returns:
true if the document is indexed, otherwise false.

Reimplemented from XalanDocument.

bool XercesDocumentBridge::isSupported ( const XalanDOMString & feature,
const XalanDOMString & version ) const [virtual]
 

Tests whether the DOM implementation implements a specific feature and that feature is supported by this node.

Parameters:
feature   The string of the feature to test. This is the same name as what can be passed to the method hasFeature on DOMImplementation.
version   This is the version number of the feature to test. In Level 2, version 1, this is the string "2.0". If the version is not specified, supporting any version of the feature will cause the method to return true.
Returns:
Returns true if the specified feature is supported on this node, false otherwise.

Reimplemented from XalanDocument.

DOM_AttrType XercesDocumentBridge::mapNode ( const XalanAttr * theXalanNode ) const
 

DOM_NodeType XercesDocumentBridge::mapNode ( const XalanNode * theXalanNode ) const
 

XalanElement * XercesDocumentBridge::mapNode ( const DOM_ElementType & theXercesNode ) const
 

XalanAttr * XercesDocumentBridge::mapNode ( const DOM_AttrType & theXercesNode ) const
 

XalanNode * XercesDocumentBridge::mapNode ( const DOM_NodeType & theXercesNode ) const
 

NodeImplType * XercesDocumentBridge::mapNodeToImpl ( const XalanNode * theXalanNode ) const
 

void XercesDocumentBridge::normalize ( ) [virtual]
 

Puts all Text nodes in the full depth of the sub-tree underneath this Node, including attribute nodes, into a "normal" form where only markup (e.g., tags, comments, processing instructions, CDATA sections, and entity references) separates Text nodes, i.e., there are no adjacent Text nodes.

This can be used to ensure that the DOM view of a document is the same as if it were saved and re-loaded, and is useful when operations (such as XPointer lookups) that depend on a particular document tree structure are to be used.

Note: In cases where the document contains CDATASections, the normalize operation alone may not be sufficient, since XPointers do not differentiate between Text nodes and CDATASection nodes.

Reimplemented from XalanDocument.

void XercesDocumentBridge::rebuildBridge ( )
 

Rebuild the entire bridge structure that connects the Xerces document to this XercesDocumentBridge instance.

This destroys the bridge before rebuilding.

XalanNode * XercesDocumentBridge::removeChild ( XalanNode * oldChild ) [virtual]
 

Removes the child node indicated by oldChild from the list of children, and returns it.

Parameters:
oldChild   The node being removed.
Returns:
The node removed.

Reimplemented from XalanDocument.

XalanNode * XercesDocumentBridge::replaceChild ( XalanNode * newChild,
XalanNode * oldChild ) [virtual]
 

Replaces the child node oldChild with newChild in the list of children, and returns the oldChild node.

If newChild is a DocumentFragment object, oldChild is replaced by all of the DocumentFragment children, which are inserted in the same order.

If the newChild is already in the tree, it is first removed.

Parameters:
newChild   The new node to put in the child list.
oldChild   The node being replaced in the list.
Returns:
The node replaced.

Reimplemented from XalanDocument.

void XercesDocumentBridge::setNodeValue ( const XalanDOMString & nodeValue ) [virtual]
 

Sets the value of the node.

Any node which can have a nodeValue (

See also:
getNodeValue) will also accept requests to set it to a string. The exact response to this varies from node to node -- Attribute, for example, stores its values in its children and has to replace them with a new Text holding the replacement value.

For most types of Node, value is null and attempting to set it will throw DOMException(NO_MODIFICATION_ALLOWED_ERR). This will also be thrown if the node is read-only.

Reimplemented from XalanDocument.

void XercesDocumentBridge::setPrefix ( const XalanDOMString & prefix ) [virtual]
 

Set the namespace prefix of this node.

Note that setting this attribute, when permitted, changes the nodeName attribute, which holds the qualified name, as well as the tagName and name attributes of the Element and Attr interfaces, when applicable.

Note also that changing the prefix of an attribute, that is known to have a default value, does not make a new attribute with the default value and the original prefix appear, since the namespaceURI and localName do not change.

Parameters:
prefix   The prefix of this node.
Exceptions:
DOMException   INVALID_CHARACTER_ERR: Raised if the specified prefix contains an illegal character.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
NAMESPACE_ERR: Raised if the specified prefix is malformed, if the specified prefix is "xml" and the namespaceURI of this node is different from "http://www.w3.org/XML/1998/namespace", if specified prefix is "xmlns" and the namespaceURI is neither null nor an empty string, or if the localName is null.
