IBufferGraph Interface

Represents a graph of ITextBuffer objects. The top level text buffer might or might not be a IProjectionBuffer.

Namespace:  Microsoft.VisualStudio.Text.Projection

public interface IBufferGraph

The IBufferGraph type exposes the following members.

Properties

	Name	Description
	TopBuffer	Gets the top text buffer in the buffer graph.

Methods

	Name	Description
	CreateMappingPoint	Creates a new IMappingPoint with the specified snapshot point and tracking mode.
	CreateMappingSpan	Initializes a new instance of a IMappingSpan.
	GetTextBuffers	Finds all the ITextBuffer objects in the graph that match the specified predicate.
	MapDownToBuffer(SnapshotSpan, SpanTrackingMode, ITextBuffer)	Maps a snapshot span in some buffer in the graph to a sequence of zero or more spans in a buffer that is lower in the graph. Source buffers are considered to be lower than the projection buffers that consume them.
	MapDownToBuffer(SnapshotPoint, PointTrackingMode, ITextBuffer, PositionAffinity)	Maps a position in the graph to the corresponding position in a buffer lower in the graph. Source buffers are considered to be lower than the projection buffers that consume them.
	MapDownToFirstMatch(SnapshotSpan, SpanTrackingMode, Predicate<ITextSnapshot>)	Maps a snapshot span in some buffer in the graph to a sequence of zero or more spans in some source snapshot selected by a predicate.
	MapDownToFirstMatch(SnapshotPoint, PointTrackingMode, Predicate<ITextSnapshot>, PositionAffinity)	Maps a position in the graph to a position in a matching buffer that is lower in the graph. Source buffers are considered to be lower than the projection buffers that consume them.
	MapDownToInsertionPoint	Maps a position in some buffer in the graph to a position in a matching buffer that is lower in the graph and to which an insertion would be routed. Source buffers are considered to be lower than the projection buffers that consume them.
	MapDownToSnapshot(SnapshotSpan, SpanTrackingMode, ITextSnapshot)	Maps a snapshot span in some buffer in the graph to a sequence of zero or more spans in a buffer that is lower in the graph. Source buffers are considered to be lower than the projection buffers that consume them.
	MapDownToSnapshot(SnapshotPoint, PointTrackingMode, ITextSnapshot, PositionAffinity)	Maps a position in the graph to the corresponding position in a snapshot lower in the graph. Source buffers are considered to be lower than the projection buffers that consume them.
	MapUpToBuffer(SnapshotSpan, SpanTrackingMode, ITextBuffer)	Maps a span in the current snapshot of some buffer that is a member of the buffer graph to a sequence of spans in a snapshot of a designated buffer.
	MapUpToBuffer(SnapshotPoint, PointTrackingMode, PositionAffinity, ITextBuffer)	Maps a position in the current snapshot of some buffer that is a member of the buffer graph to a snapshot of some buffer.
	MapUpToFirstMatch(SnapshotSpan, SpanTrackingMode, Predicate<ITextSnapshot>)	Maps a span in the current snapshot of some buffer that is a member of the buffer graph up to a sequence of spans in a snapshot of some buffer that is selected by a predicate.
	MapUpToFirstMatch(SnapshotPoint, PointTrackingMode, Predicate<ITextSnapshot>, PositionAffinity)	Maps a position in the current snapshot of some buffer that is a member of the buffer graph to a snapshot of some buffer that is selected by a predicate.
	MapUpToSnapshot(SnapshotSpan, SpanTrackingMode, ITextSnapshot)	Maps a span in the current snapshot of a buffer that is a member of the buffer graph to a sequence of spans in a snapshot of a designated buffer.
	MapUpToSnapshot(SnapshotPoint, PointTrackingMode, PositionAffinity, ITextSnapshot)	Maps a position in the current snapshot of a buffer that is a member of the buffer graph to the specified snapshot.

Events

	Name	Description
	GraphBufferContentTypeChanged	Occurs when the IContentType of any ITextBuffer in the buffer graph changes.
	GraphBuffersChanged	Occurs when the set of ITextBuffer objects in the buffer graph changes.
