Returns

IClassificationType

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 Register(IClassificationType classificationType, IHighlightingStyle style, bool overwriteExisting = false)

Parameter	Type	Description
classificationType	IClassificationType	The IClassificationType with which to register the IHighlightingStyle.
style	IHighlightingStyle	The IHighlightingStyle to register.
overwriteExisting	bool	Whether to overwrite existing highlighting styles with the same IClassificationType.

Returns

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)

bool:

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