CPatternHandler

CPatternHandler();

Constructs the pattern handler.

~CPatternHandler

virtual ~CPatternHandler();

Destroys the pattern handler.

Match

virtual bool Match(const XNode &pNode) = 0;

Matches the XDM node against this pattern.

Parameters:

pNode - the XDM node to match

Returns:

true if the given node mathes this pattern; false otherwise

Match

virtual bool Match(const XNode &pNode, double &dblPriority) = 0;

Matches the XDM node against this pattern, returns the effective pattern priority.

The effective priority is defined as the maximum priority among all location path patterns (that is, parts of this pattern conforming to the LocationPartPattern syntax defined in XSLT) that match the given node.

Parameters:

pNode - the XDM node to match

dblPriority - on return, the effective priority; unspecified if match failed

Returns:

true if the given node mathes this pattern; false otherwise
