Assembly: Microsoft.VisualStudio.TextManager.Interop (in Microsoft.VisualStudio.TextManager.Interop.dll)

Syntax

'Declaration
Function MapLocalSpansToTextOriginatingLayer ( _
    dwFlags As UInteger, _
    pLocalSpanEnum As IVsEnumTextSpans, _
    <OutAttribute> ByRef ppTargetLayer As IVsTextLayer, _
    <OutAttribute> ByRef ppTargetSpanEnum As IVsEnumTextSpans _
) As Integer

int MapLocalSpansToTextOriginatingLayer(
    uint dwFlags,
    IVsEnumTextSpans pLocalSpanEnum,
    out IVsTextLayer ppTargetLayer,
    out IVsEnumTextSpans ppTargetSpanEnum
)

int MapLocalSpansToTextOriginatingLayer(
    [InAttribute] unsigned int dwFlags, 
    [InAttribute] IVsEnumTextSpans^ pLocalSpanEnum, 
    [OutAttribute] IVsTextLayer^% ppTargetLayer, 
    [OutAttribute] IVsEnumTextSpans^% ppTargetSpanEnum
)

abstract MapLocalSpansToTextOriginatingLayer : 
        dwFlags:uint32 * 
        pLocalSpanEnum:IVsEnumTextSpans * 
        ppTargetLayer:IVsTextLayer byref * 
        ppTargetSpanEnum:IVsEnumTextSpans byref -> int

function MapLocalSpansToTextOriginatingLayer(
    dwFlags : uint, 
    pLocalSpanEnum : IVsEnumTextSpans, 
    ppTargetLayer : IVsTextLayer, 
    ppTargetSpanEnum : IVsEnumTextSpans
) : int

Parameters

dwFlags
Type: System.UInt32
[in] One of the MapLocalSpanFlags values.

pLocalSpanEnum
Type: Microsoft.VisualStudio.TextManager.Interop.IVsEnumTextSpans
[in] The local text spans to be mapped.

ppTargetLayer
Type: Microsoft.VisualStudio.TextManager.Interop.IVsTextLayer%
[out] The shallowest layer that originates text.

ppTargetSpanEnum
Type: Microsoft.VisualStudio.TextManager.Interop.IVsEnumTextSpans%
[out] The mapped layer set of text spans.

Return Value

Type: System.Int32
If the method succeeds, it returns S_OK. If it fails, it returns an error code.

Remarks

COM Signature

From textmgr.idl:

HRESULT IVsTextLayer::MapLocalSpansToTextOriginatingLayer(
   [in] DWORD dwFlags,
   [in] IVsEnumTextSpans *pLocalSpanEnum,
   [out] IVsTextLayer **ppTargetLayer,
   [out] IVsEnumTextSpans **ppTargetSpanEnum
);

MapLocalSpansToTextOriginatingLayer will take a set of local spans and map them down to the shallowest layer that originates text. You are not guaranteed that you will get back the layer that actually originates a given set of text, that is, text which excludes non-text atoms.
