CollectionTagger<T> Class

public abstract class CollectionTagger<T> : TaggerBase<T>, ICollectionTagger<T>, ITagger<T>, ITaggerBase, IOrderable, IKeyedObject where T : class, ITag

protected CollectionTagger(string key, IEnumerable<Ordering> orderings, ICodeDocument document, bool isForLanguage)

Parameter	Type	Description
key	string	The string-based key that identifies the object.
orderings	IEnumerable<Ordering>	The collection of Ordering objects, used to determine how this object is positioned relative to other objects.
document	ICodeDocument	The document to which this manager is attached.
isForLanguage	bool	Indicates whether this tagger is for a language. If true, the tagger is closed when the document's language changes.

public int Count { get; }

Property Value

int:

The number of elements contained in the collection.

public TagVersionRange<T> this[T tag] { get; }

Parameter	Type	Description
tag	T	The tag for which to search.

Property Value

TagVersionRange<T>:

The tag range that points to the specified tag.

public TagVersionRange<T> Add(ITextSnapshotLine snapshotLine, T tag)

Parameter	Type	Description
snapshotLine	ITextSnapshotLine	The target ITextSnapshotLine.
tag	T	The ITag to add.

Returns

TagVersionRange<T>:

The TagVersionRange<T> that was created.

Remarks

The generated ITextVersionRange is created with the DeleteWhenZeroLength and LineBased flags.

public void Add(TagVersionRange<T> tagRange)

Parameter	Type	Description
tagRange	TagVersionRange<T>	The tag range to add to the collection.

Remarks

This is the lowest-level method used for adding a tag range, and gives the most control over snapshot translation options.

public TagVersionRange<T> Add(TextSnapshotRange snapshotRange, T tag)

Parameter	Type	Description
snapshotRange	TextSnapshotRange	The target TextSnapshotRange.
tag	T	The ITag to add.

Returns

TagVersionRange<T>:

The TagVersionRange<T> that was created.

Remarks

The generated ITextVersionRange is created with the DeleteWhenZeroLength flag.

public void Clear()

public bool Contains(TagVersionRange<T> tagRange)

Parameter	Type	Description
tagRange	TagVersionRange<T>	The object to locate in the collection.

Returns

bool:

true if the item is found in the collection; otherwise, false.

public void CopyTo(TagVersionRange<T>[] array, int arrayIndex)

Parameter	Type	Description
array	TagVersionRange<T>[]	The one-dimensional Array that is the destination of the elements copied from the collection. The Array must have zero-based indexing.
arrayIndex	int	The zero-based index in array at which copying begins.

public IDisposable CreateBatch()

Returns

IDisposable:

An IDisposable object. Once disposed, the batch is ended.

public TagVersionRange<T> FindNext(ITextSnapshotLine snapshotLine, ITagSearchOptions<T> options)

Parameter	Type	Description
snapshotLine	ITextSnapshotLine	The ITextSnapshotLine from which to start the search.
options	ITagSearchOptions<T>	The optional ITagSearchOptions<T> that specifies search options.

Returns

TagVersionRange<T>:

The TagVersionRange<T> that was found, if any.

public TagVersionRange<T> FindNext(TextSnapshotOffset snapshotOffset, ITagSearchOptions<T> options)

Parameter	Type	Description
snapshotOffset	TextSnapshotOffset	The TextSnapshotOffset from which to start the search.
options	ITagSearchOptions<T>	The optional ITagSearchOptions<T> that specifies search options.

Returns

TagVersionRange<T>:

The TagVersionRange<T> that was found, if any.

public IEnumerator<TagVersionRange<T>> GetEnumerator()

Returns

IEnumerator<TagVersionRange<T>>:

An IEnumerator object for the entire collection

Remarks

Enumerators are intended to be used only to read data in the collection. Enumerators cannot be used to modify the underlying collection.

The enumerator does not have exclusive access to the collection.

When an enumerator is instantiated, it takes a snapshot of the current state of the collection. If changes are made to the collection, such as adding, modifying or deleting elements, the snapshot gets out of sync and the enumerator throws an InvalidOperationException. Two enumerators instantiated from the same collection at the same time can have different snapshots of the collection.

public override IEnumerable<TagSnapshotRange<T>> GetTags(NormalizedTextSnapshotRangeCollection snapshotRanges, object parameter)

Parameter	Type	Description
snapshotRanges	NormalizedTextSnapshotRangeCollection	The collection of normalized snapshot ranges.
parameter	object	An optional parameter that provides contextual information about the tag request.

Returns

IEnumerable<TagSnapshotRange<T>>:

The tag ranges that intersect with the specified normalized snapshot ranges.

public bool Remove(TagVersionRange<T> tagRange)

Parameter	Type	Description
tagRange	TagVersionRange<T>	The tag range to remove from the collection.

Returns

bool:

true if the tag range was successfully removed from the collection; otherwise, false

public bool Remove(T tag)

Parameter	Type	Description
tag	T	The ITag to remove from the collection.

Returns

bool:

true if the tag was successfully removed from the collection; otherwise, false

public int RemoveAll(Predicate<TagVersionRange<T>> match)

Parameter	Type	Description
match	Predicate<TagVersionRange<T>>	The predicate that defines the conditions for removal.

Returns

int:

The number of objects that were removed.

public TagVersionRange<T> Toggle(ITextSnapshotLine snapshotLine, T tag)

Parameter	Type	Description
snapshotLine	ITextSnapshotLine	The target ITextSnapshotLine.
tag	T	The ITag to add, if no tag is already on the line.

Returns

TagVersionRange<T>:

The TagVersionRange<T> that was created, if a tag was added.

public TagVersionRange<T> Toggle(TextSnapshotRange snapshotRange, T tag)

Parameter	Type	Description
snapshotRange	TextSnapshotRange	The target TextSnapshotRange.
tag	T	The ITag to add, if no tag is already in the text range.
