Examples of org.eclipse.jface.text.projection.ProjectionDocumentEvent

org.eclipse.jface.text.projection.ProjectionDocumentEvent
This event is sent out by an {@link org.eclipse.jface.text.projection.ProjectionDocument}when it is manipulated. The manipulation is either a content manipulation or a change of the projection between the master and the slave. Clients can determine the type of change by asking the projection document event for its change type (see {@link #getChangeType()}) and comparing it with the predefined types {@link #PROJECTION_CHANGE}and {@link #CONTENT_CHANGE}.
Clients are not supposed to create instances of this class. Instances are created by {@link org.eclipse.jface.text.projection.ProjectionDocument}instances. This class is not intended to be subclassed.
@since 3.0 @noinstantiate This class is not intended to be instantiated by clients. @noextend This class is not intended to be subclassed by clients.
