ExpansionProvider.IsValidType Method

Definition

Namespace:

Microsoft.VisualStudio.Package

Assembly:

Microsoft.VisualStudio.Package.LanguageService.15.0.dll

Package:

Microsoft.VisualStudio.Package.LanguageService.15.0 v17.12.40392

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.

public:
 virtual int IsValidType(Microsoft::VisualStudio::TextManager::Interop::IVsTextLines ^ buffer, cli::array <Microsoft::VisualStudio::TextManager::Interop::TextSpan> ^ ts, cli::array <System::String ^> ^ rgTypes, int iCountTypes, [Runtime::InteropServices::Out] int % fIsValid);

 virtual int IsValidType(Microsoft::VisualStudio::TextManager::Interop::IVsTextLines const & buffer, std::Array <Microsoft::VisualStudio::TextManager::Interop::TextSpan> const & ts, std::Array <std::wstring const &> const & rgTypes, int iCountTypes, [Runtime::InteropServices::Out] int & fIsValid);

public virtual int IsValidType (Microsoft.VisualStudio.TextManager.Interop.IVsTextLines buffer, Microsoft.VisualStudio.TextManager.Interop.TextSpan[] ts, string[] rgTypes, int iCountTypes, out int fIsValid);

abstract member IsValidType : Microsoft.VisualStudio.TextManager.Interop.IVsTextLines * Microsoft.VisualStudio.TextManager.Interop.TextSpan[] * string[] * int * int -> int
override this.IsValidType : Microsoft.VisualStudio.TextManager.Interop.IVsTextLines * Microsoft.VisualStudio.TextManager.Interop.TextSpan[] * string[] * int * int -> int

Public Overridable Function IsValidType (buffer As IVsTextLines, ts As TextSpan(), rgTypes As String(), iCountTypes As Integer, ByRef fIsValid As Integer) As Integer

Parameters

buffer

IVsTextLines

The IVsTextLines buffer.

ts

TextSpan[]

An array of TextSpan objects.

rgTypes

String[]

An array of expansion types.

iCountTypes

Int32

The number of expansion types in the rgTypes array.

fIsValid

Int32

[out] Returns true if the type is valid, otherwise false.

Returns

Int32

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

Implements

IsValidType(IVsTextLines, TextSpan[], 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.
