ExpansionProvider.IsValidType Method

Determines whether or not a given type is valid for expansion purposes. This method should be overridden if you want to specify where in the source document the expansion can take place.

    buffer : IVsTextLines, 
    ts : TextSpan[], 
    rgTypes : String[], 
    iCountTypes : int, 
    fIsValid : int
) : int

Parameters

  • rgTypes
    Type: array<System.String[]
    An array of expansion types.
  • iCountTypes
    Type: System.Int32
    The number of expansion types in the rgTypes array.
  • fIsValid
    Type: System.Int32%
    [out] Returns true if the type is valid, otherwise false.

Return Value

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

Implements

IVsExpansionClient.IsValidType(IVsTextLines, array<TextSpan[], array<String[], Int32, 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.
