Microsoft.VisualStudio.Text.Tagging Namespace

Tagging is a way of adding markers to spans of text in the editor.

Classes

BatchedTagsChangedEventArgs	Provides a list of all mapping spans where tags have changed since the last BatchedTagsChanged event. The BatchedTagsChanged event is raised on the same thread as the thread that created the tag aggregator.
BracePairTag	An implementation of IBracePairTag
ClassificationTag	An implementation of IClassificationTag.
ErrorTag	An implementation of IErrorTag.
MappingTagSpan<T>	The implementation of IMappingTagSpan<T>.
OutliningRegionTag	Represents a tag for outlining regions.
OverviewMarkTag	An implementation of IOverviewMarkTag.
SimpleTagger<T>	Provides simple, thread-safe storage of and interaction with tags of the given type.
SpaceNegotiatingAdornmentTag	Represents a tag for a space-negotiating adornment. The tag is used to provide space for positioning the adornment in a view.
StructureTag	An implementation of IStructureTag2.
TagsChangedEventArgs	Provides information about the ITagAggregator<T>.TagsChanged event.
TagSpan<T>	The implementation of ITagSpan<T>.
TagTypeAttribute	Declares the types of tags an ITagger<T> produces. This attribute is placed on the provider of the tagger.
TextMarkerTag	Represents the text marker tag, which is used to place text marker adornments on a view.
TrackingTagSpan<T>	Associates an ITag with a given ITrackingSpan. This is used by SimpleTagger to provide buffer-level tracking and caching of tag spans.
UrlTag	An implementation of IUrlTag.

Structs

SubHeadingStructureData

Define the subHeadingStructureData which provide below information: Get the whole span of this code block. Gets the span of the statement that controls the structural block. Determines the semantic type of the structural block.

Interfaces

IAccurateTagAggregator<T>	Aggregates all the tag providers in a buffer graph for the specified type of tag.
IAccurateTagger<T>	A provider of tags over a buffer.
IBracePairTag	An ITag that denotes the location of a brace pair
IBufferTagAggregatorFactoryService	A factory that creates an ITagAggregator<T> for an ITextBuffer.
IClassificationTag	A tag that represents a classification type.
IContainerStructureTag	Extends IStructureTag with SubHeadings property improving structure visualization support for secondary structure elements such as C# "else" statement, also support for the "catch" and "case"statement.
IEndOfLineAdornmentTag	Used to indicate the rectangle covered by an adornment (allowing participating adornments to adjust themselves if needed).
IErrorTag	Represents an error, which is used to place squiggle adornments on the view.
IMappingTagSpan<T>	Associates an ITag with a specified IMappingSpan.
IOutliningRegionTag	Provides a tag for outlining regions.
IOverviewMarkTag	Provides the information needed to render a mark in the overview margin.
IStructureTag	Represents a structural code block, which is used for vertical structural line adornments and outlining collapse regions.
IStructureTag2	Extends IStructureTag with PrimaryHeaderSpan property improving structure visualization support for secondary structure elements such as C# "else" statement.
ITag	The base interface of all tags.
ITagAggregator<T>	Aggregates all the tag providers in a buffer graph for the specified type of tag.
ITagger<T>	A provider of tags over a buffer.
ITaggerProvider	Creates an ITagger<T> for a given buffer.
ITagSpan<T>	Associates an ITag with a given SnapshotSpan.
ITextMarkerTag	Represents the text marker tag, which is used to place text marker adornments on a view.
IUrlTag	A tag that represents a URL.
IViewTagAggregatorFactoryService	A service that creates an ITagAggregator<T> for an ITextView. This is a MEF component part, and should be imported as follows: [Import] IViewLevelTagAggregatorFactoryService factory = null;
IViewTaggerProvider	Creates an ITagger<T> for a given buffer.

Enums

TagAggregatorOptions	Tag Aggregator options.
TagAggregatorOptions2	Tag Aggregator options.
