Method Detail

getNodeType

public short getNodeType()

Description copied from class: NodeImpl

A code representing the type of the underlying object, as defined above.

Specified by:

getNodeType in interface org.w3c.dom.Node

Specified by:

getNodeType in class NodeImpl

getName

public String getName()

Returns the name of this attribute.

Specified by:

getName in interface org.w3c.dom.Attr

setSymbolID

public void setSymbolID(short symbolID)

getSymbolID

public short getSymbolID()

Description copied from interface: CompressedNode

getSymbolID returns the Symbol ID for the current node. Some nodes will not have a Symbol ID, in which case, a value of -1 is returned.

Specified by:

getSymbolID in interface CompressedNode

Overrides:

getSymbolID in class NodeImpl

setNodeValue

public void setNodeValue(String nodeValue)
                  throws org.w3c.dom.DOMException

Description copied from class: NodeImpl

The value of this node, depending on its type; see the table above. When it is defined to be null , setting it has no effect.

Specified by:

setNodeValue in interface org.w3c.dom.Node

Overrides:

setNodeValue in class NodeImpl

Throws:

org.w3c.dom.DOMException -

• NO_MODIFICATION_ALLOWED_ERR: Raised when the node is readonly.
• DOMSTRING_SIZE_ERR: Raised when it would return more characters than fit in a DOMString variable on the implementation platform.

setValue

public void setValue(String value)

Specified by:

setValue in interface org.w3c.dom.Attr

isNodeTypeValid

protected boolean isNodeTypeValid(short type)

Overrides:

isNodeTypeValid in class ContainerNodeImpl

getSpecified

public boolean getSpecified()

If this attribute was explicitly given a value in the original document, this is true; otherwise, it is false. Note that the implementation is in charge of this attribute, not the user. If the user changes the value of the attribute (even if it ends up having the same value as the default value) then the specified flag is automatically flipped to true. To re-specify the attribute as the default value from the DTD, the user must delete the attribute. The implementation will then make a new attribute available with specified set to false and the default value (if one exists).
In summary: If the attribute has an assigned value in the document then specified is true, and the value is the assigned value. If the attribute has no assigned value in the document and has a default value in the DTD, then specified is false, and the value is the default value in the DTD. If the attribute has no assigned value in the document and has a value of #IMPLIED in the DTD, then the attribute does not appear in the structure model of the document.

Specified by:

getSpecified in interface org.w3c.dom.Attr

setSpecified

public void setSpecified(boolean specified)

getValue

public String getValue()

On retrieval, the value of the attribute is returned as a string. Character and general entity references are replaced with their values.
On setting, this creates a Text node with the unparsed contents of the string.

Specified by:

getValue in interface org.w3c.dom.Attr

getNodeValue

public String getNodeValue()

Description copied from class: NodeImpl

The value of this node, depending on its type; see the table above.

Specified by:

getNodeValue in interface org.w3c.dom.Node

Overrides:

getNodeValue in class NodeImpl

getOwnerElement

public org.w3c.dom.Element getOwnerElement()

Specified by:

getOwnerElement in interface org.w3c.dom.Attr

Since:

DOM Level 2

getSchemaTypeInfo

public org.w3c.dom.TypeInfo getSchemaTypeInfo()

Since:

DOM Level 3

isId

public boolean isId()

Since:

DOM Level 3
