IMatchesCriteriaCallBack::EvaluateContextNode method
When overridden in a derived class, evaluates whether a specified IContextNode object meets the criteria.
Syntax
HRESULT EvaluateContextNode(
[in] IContextNode *pContextNodeToEvaluate,
[out] VARIANT_BOOL *pbResult
);
Parameters
-
pContextNodeToEvaluate [in]
-
The IContextNode object to evaluate.
-
pbResult [out]
-
VARIANT_TRUE if pContextNodeToEvaluate matches the criteria; otherwise, VARIANT_FALSE.
Return value
For a description of the return values, see Classes and Interfaces - Ink Analysis.
Remarks
To use IInkAnalyzer::FindNodesWithCallBack Method or IInkAnalyzer::FindNodesWithCallBackInSubTree Method, create a class that implements IMatchesCriteriaCallBack. Implement IMatchesCriteriaCallBack::EvaluateContextNode to return VARIANT_TRUE if the IContextNode object matches your criteria, and VARIANT_FALSE otherwise. For some criteria, you may need to provide a means of initializing or maintaining the state of your IMatchesCriteriaCallBack object.
