Implements
IVsTextViewFilter.GetPairExtents(Int32, Int32, array<TextSpan[])
Remarks
This method is called to retrieve the span that encompasses the innermost matching pair of language elements (such as "{" and "}" in C# or "<" and ">" in XML) that contains the specified location.
This method is an implementation of the GetPairExtents method on the IVsTextViewFilter interface.
The base method validates the parameters, and then forwards the call to the GetPairExtents method on the Source object that was obtained in the ViewFilter constructor.
