public HighlightingStyleRegistry()

public ICollection<IClassificationType> ClassificationTypes { get; }

public IHighlightingStyle this[IClassificationType classificationType] { get; }

public IClassificationType GetClassificationType(string key)

Parameter	Type	Description

The IClassificationType, if any, that has been registered with the specified key.

public IEnumerator<KeyValuePair<IClassificationType, IHighlightingStyle>> GetEnumerator()

Returns

IEnumerator<KeyValuePair<IClassificationType, IHighlightingStyle>>:

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 bool ImportHighlightingStyles(Stream stream)

stream	Stream	The Stream from which to import.

Returns

Boolean:

true if settings were imported; otherwise, false.

protected virtual void OnChanged(EventArgs e)

Parameter	Type	Description
e	EventArgs	An EventArgs that contains the event data.

public bool Register(IClassificationType classificationType, IHighlightingStyle style)

Parameter	Type	Description
classificationType	IClassificationType	The IClassificationType with which to register the IHighlightingStyle.
style	IHighlightingStyle	The IHighlightingStyle to register.

Returns

Boolean:

true if the IHighlightingStyle was added; otherwise, false.

Remarks

This method only returns false if there is already an IHighlightingStyle registered with the same IClassificationType.

public bool Register(IClassificationType classificationType, IHighlightingStyle style, bool overwriteExisting)

classificationType	IClassificationType	The IClassificationType with which to register the IHighlightingStyle.
style	IHighlightingStyle	The IHighlightingStyle to register.
overwriteExisting	Boolean	Whether to overwrite existing highlighting styles with the same IClassificationType.

Returns

Boolean:

true if the IHighlightingStyle was added; otherwise, false.

Remarks

This method only returns false if overwriteExisting is false and there is already an IHighlightingStyle registered with the same IClassificationType.

public bool Unregister(IClassificationType classificationType)

Parameter	Type	Description
classificationType	IClassificationType	The IClassificationType to unregister.

Returns

Boolean:

true if the registry entry was removed; otherwise, false.

public event EventHandler Changed
