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.

Namespace:  Microsoft.VisualStudio.Package

Syntax

'Декларация
Public Overridable Function IsValidType ( _
    buffer As IVsTextLines, _
    ts As TextSpan(), _
    rgTypes As String(), _
    iCountTypes As Integer, _
    <OutAttribute> ByRef fIsValid As Integer _
) As Integer
public virtual int IsValidType(
    IVsTextLines buffer,
    TextSpan[] ts,
    string[] rgTypes,
    int iCountTypes,
    out int fIsValid
)

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.
