Member Function Documentation

bool XercesDOMWalker::endNode ( DOMNodeType * node ) [protected, virtual]

Called when leaving a node. Parameters: node   The node Returns: return false if traversal should continue, or true if it should not.

bool XercesDOMWalker::endNode ( const DOMNodeType * node ) [protected, pure virtual]

Called when leaving a node. Parameters: node   The node Returns: return false if traversal should continue, or true if it should not. Reimplemented in XercesDocumentWrapper::BuildWrapperTreeWalker, and XercesDOMFormatterWalker.

bool XercesDOMWalker::startNode ( DOMNodeType * node ) [protected, virtual]

Called when first walking a node. Parameters: node   The node Returns: return false if traversal should continue, or true if it should not.

bool XercesDOMWalker::startNode ( const DOMNodeType * node ) [protected, pure virtual]

Called when first walking a node. Parameters: node   The node Returns: return false if traversal should continue, or true if it should not. Reimplemented in XercesDocumentWrapper::BuildWrapperTreeWalker, and XercesDOMFormatterWalker.

DOMNodeType * XercesDOMWalker::traverse ( DOMNodeType * pos, DOMNodeType * parent )

Perform a document-order traversal stopping at the provided parent node. Derived classes and stop the traversal by returning true from startNode() or endNode(). If that happens, the function will return the next node in document order. If desired, the caller can start traversing the tree again from that point. Note that terminal nodes will always have startNode() and endNode() called before the traversal terminates. Parameters: pos   The node in the tree with which to start the walk parent   The parent of pos. Note that for multiple calls that continue the traversal, this node must remain the same. Returns: parent if the traversal completes, or the next node if the traversal doesn't complete.

const DOMNodeType * XercesDOMWalker::traverse ( const DOMNodeType * pos, const DOMNodeType * parent )

Perform a document-order traversal stopping at the provided parent node. Derived classes and stop the traversal by returning true from startNode() or endNode(). If that happens, the function will return the next node in document order. If desired, the caller can start traversing the tree again from that point. Note that terminal nodes will always have startNode() and endNode() called before the traversal terminates. Parameters: pos   The node in the tree with which to start the walk parent   The parent of pos. Note that for multiple calls that continue the traversal, this node must remain the same. Returns: parent if the traversal completes, or the next node if the traversal doesn't complete.

DOMNodeType * XercesDOMWalker::traverse ( DOMNodeType * pos )

Perform a document-order traversal. Derived classes and stop the traversal by returning true from startNode() or endNode(). If that happens, the function will return the next node in document order. If desired, the caller can start traversing the tree again from that point. Note that terminal nodes will always have startNode() and endNode() called before the traversal terminates. Parameters: pos   The node in the tree with which to start the walk Returns: 0 if the traversal completes, or the next node if the traversal doesn't complete.

const DOMNodeType * XercesDOMWalker::traverse ( const DOMNodeType * pos )

Perform a document-order traversal. Derived classes and stop the traversal by returning true from startNode() or endNode(). If that happens, the function will return the next node in document order. If desired, the caller can start traversing the tree again from that point. Note that terminal nodes will always have startNode() and endNode() called before the traversal terminates. Parameters: pos   The node in the tree with which to start the walk Returns: 0 if the traversal completes, or the next node if the traversal doesn't complete.

void XercesDOMWalker::traverseSubtree ( DOMNodeType * pos )

Perform a document-order traversal. Parameters: pos   starting node

void XercesDOMWalker::traverseSubtree ( const DOMNodeType * pos )

Perform a pre-order traversal. Parameters: pos   starting node
