    fIsValid : int
) : int

Parameters

• buffer
  Type: Microsoft.VisualStudio.TextManager.Interop.IVsTextLines

  The IVsTextLines buffer.

• ts
  Type: array<Microsoft.VisualStudio.TextManager.Interop.TextSpan[]

  An array of TextSpan objects.

• bstrKind
  Type: String

  The kind of expansion to perform.

• fIsValid
  Type: Int32%

  [out] Returns true if it is a valid expansion kind, otherwise false.

Return Value

Type: 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.
