IProjectionBufferBase Interface

A text buffer that contains projections of other text buffers, composed of a list of text spans of those buffers. The other buffers that contribute to the projection buffer are called source buffers, and the text spans that describe the contributed regions are called source spans.

Namespace:  Microsoft.VisualStudio.Text.Projection

The IProjectionBufferBase type exposes the following members.

Properties

	Name	Description
	ContentType	Gets the content type of the text in the buffer. (Inherited from ITextBuffer.)
	CurrentSnapshot	Gets the current content of the buffer. (Inherited from ITextBuffer.)
	CurrentSnapshot	Gets the current snapshot of the contents of the projection buffer.
	EditInProgress	Determines whether an edit operation is currently in progress on the ITextBuffer. (Inherited from ITextBuffer.)
	Properties	Gets the collection of properties controlled by the property owner. (Inherited from IPropertyOwner.)
	SourceBuffers	Gets the set of ITextBuffer objects that directly contribute to the projection buffer.

Methods

	Name	Description
	ChangeContentType	Changes the IContentType for this ITextBuffer. (Inherited from ITextBuffer.)
	CheckEditAccess	Determines whether edit operations on this text buffer are permitted on the calling thread. (Inherited from ITextBuffer.)
	CreateEdit()	Creates an ITextEdit object that handles compound edit operations on this buffer. (Inherited from ITextBuffer.)
	CreateEdit(EditOptions, Nullable<Int32>, Object)	Creates an ITextEdit object that handles compound edit operations on this buffer. (Inherited from ITextBuffer.)
	CreateReadOnlyRegionEdit	Creates an IReadOnlyRegionEdit object that handles adding or removing read-only regions from this buffer. (Inherited from ITextBuffer.)
	Delete(Span)	Deletes a sequence of characters from the buffer. (Inherited from ITextBuffer.)
	Delete(Span)	Deletes a span of characters from the buffer.
	GetReadOnlyExtents	Gets a list of read-only regions that overlap the given span. (Inherited from ITextBuffer.)
	Insert(Int32, String)	Inserts the given text at the specified position in the ITextBuffer. (Inherited from ITextBuffer.)
	Insert(Int32, String)	Inserts the specified text at the specified position in the ITextBuffer.
	IsReadOnly(Int32)	Determines whether a text insertion would be prohibited at the specified position due to an IReadOnlyRegion. (Inherited from ITextBuffer.)
	IsReadOnly(Span)	Determines whether a text modification or deletion would be prohibited at span due to an IReadOnlyRegion. (Inherited from ITextBuffer.)
	IsReadOnly(Int32, Boolean)	Determines whether a text insertion would be prohibited at the specified position due to an IReadOnlyRegion. (Inherited from ITextBuffer.)
	IsReadOnly(Span, Boolean)	Determines whether a text modification or deletion would be prohibited at span due to an IReadOnlyRegion. (Inherited from ITextBuffer.)
	Replace(Span, String)	Replaces a sequence of characters with different text. This is equivalent to first deleting the text to be replaced and then inserting the new text. (Inherited from ITextBuffer.)
	Replace(Span, String)	Replaces a span of characters with different text. This is equivalent to first deleting the text to be replaced and then inserting the new text.
	TakeThreadOwnership	Claims ownership of this buffer for the current thread. All subsequent modifications of this ITextBuffer must be made from the current thread, or else an InvalidOperationException will be raised. (Inherited from ITextBuffer.)

Events

	Name	Description
	Changed	Occurs when a non-empty ITextEdit is successfully applied. (Inherited from ITextBuffer.)
	ChangedHighPriority	Occurs when a non-empty ITextEdit is successfully applied. (Inherited from ITextBuffer.)
	ChangedLowPriority	Occurs when a non-empty ITextEdit is successfully applied. (Inherited from ITextBuffer.)
	Changing	Occurs just before a non-empty ITextEdit is applied. (Inherited from ITextBuffer.)
	ContentTypeChanged	Occurs whenever the IContentType has been changed. (Inherited from ITextBuffer.)
	PostChanged	Occurs after the Changed event and any resulting edits. (Inherited from ITextBuffer.)
	ReadOnlyRegionsChanged	Occurs when a IReadOnlyRegionEdit has created or removed read-only regions. (Inherited from ITextBuffer.)
