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.

Namespace: Microsoft.VisualStudio.Package
Assemblies:   Microsoft.VisualStudio.Package.LanguageService.10.0 (in Microsoft.VisualStudio.Package.LanguageService.10.0.dll)
  Microsoft.VisualStudio.Package.LanguageService (in Microsoft.VisualStudio.Package.LanguageService.dll)

Syntax

'Declaration
Public Overridable Function IsValidKind ( _
    buffer As IVsTextLines, _
    ts As TextSpan(), _
    bstrKind As String, _
    <OutAttribute> ByRef fIsValid As Integer _
) As Integer

public virtual int IsValidKind(
    IVsTextLines buffer,
    TextSpan[] ts,
    string bstrKind,
    out int fIsValid
)

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: System.String
The kind of expansion to perform.

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.
