Examples of org.eclipse.ui.texteditor.AbstractMarkerAnnotationModel

org.eclipse.ui.texteditor.AbstractMarkerAnnotationModel
Abstract implementation of a marker-based annotation model.
Markers are provided by an underlying source (a subclass responsibility). Markers whose textual range gets deleted during text editing are removed from the model on save. The {@link #updateMarkers(IDocument)} method can be usedto force the model to update the source's markers with any changes to their locations due to edits. Clients can register a {@link org.eclipse.ui.texteditor.IMarkerUpdater}objects in order to define the process of marker updating. Registration can be done using the "org.eclipse.ui.markerUpdaters" extension point.

Subclasses must implement the following methods:
- retrieveMarkers
- isAcceptable
- deleteMarkers
- listenToMarkerChanges
