ExpansionProvider.IsValidKind Method

Determines whether this is valid text for expansion. This method should be overridden if you want to specify where in the source document the expansion can take place.

public function IsValidKind(
    buffer : IVsTextLines, 
    ts : TextSpan[], 
    bstrKind : String, 
    fIsValid : int
) : int

Parameters

  • fIsValid
    Type: System.Int32%
    [out] Returns true if it is a valid expansion kind, otherwise false.

Return Value

Type: System.Int32
When overridden in derived classes, S_OK if the method succeeds, otherwise an error code.

Implements

IVsExpansionClient.IsValidKind(IVsTextLines, array<TextSpan[], String, Int32%)

Remarks

This method by default checks only that buffer is the same as the IVsTextLines of Source; it will throw an ArgumentException if not. Implementers must override this method if they wish to specify where in a document a given expansion can be performed.
