Detailed Description

Class for holding lists of DOMNodes.

This class is used primarily for holding lists of nodes found during XPath processing. It is also used for xpath-filter which requires multiple list comparisons.

It is not implemented using one of the container classes as it has the potential to become a real bottleneck. It could potentially be implemented as a hash list based on names of nodes (or even pointers).

Constructor & Destructor Documentation

XSECXPathNodeList::XSECXPathNodeList (  unsigned int  initialSize = _XSEC_NODELIST_DEFAULT_SIZE  )

XSECXPathNodeList::XSECXPathNodeList (  const XSECXPathNodeList &  other  )

Copy Constructor. Note: The XSEC Library generally passes NodeLists around as pointers. There is a LARGE overhead associated with re-creating lists, so we try to avoid doing it unless necessary.

Member Function Documentation

void XSECXPathNodeList::addNode (  const XERCES_CPP_NAMESPACE_QUALIFIER DOMNode *  n  )

Add a node to the list. Checks to see whether the node is already in the list, and if not adds it. Parameters: n  The node to add.

void XSECXPathNodeList::clear (  void   )

Clear out the entire list, deleting all entries.

const XERCES_CPP_NAMESPACE_QUALIFIER DOMNode* XSECXPathNodeList::getFirstNode (  void   )

Get the first node in the list. Returns the first node in the list of nodes and resets the search list. Returns: The first node in the list or NULL if none exist

const XERCES_CPP_NAMESPACE_QUALIFIER DOMNode* XSECXPathNodeList::getNextNode (  void   )

Get the next node in the list. Returns the next node in the list. Returns: The next node in the list of NULL if none exist

bool XSECXPathNodeList::hasNode (  const XERCES_CPP_NAMESPACE_QUALIFIER DOMNode *  n  )

Check if a node exists in the list. Parameters: n  The node to find in the list.

void XSECXPathNodeList::intersect (  const XSECXPathNodeList &  toIntersect  )

Intersect with nodeset. Delete any nodes in my list that are not in the intersect list Parameters: toIntersect  The list to intersect with.

XSECXPathNodeList& XSECXPathNodeList::operator= (  const XSECXPathNodeList &  toCopy  )

Assignment Operator. Set one node list equal to another. Note: Do not do this frequently, particularly for large lists as it will replicate the entire list and is a fairly expensive operation Parameters: toCopy  The list to be copied from

void XSECXPathNodeList::removeNode (  const XERCES_CPP_NAMESPACE_QUALIFIER DOMNode *  n  )

Remove a node from the list. Given a node, find it in the list and (if it exists) delete it from the list. Parameters: n  The node to be removed.
