Marker Updaters

Identifier: org.eclipse.ui.markerUpdaters

Description: This extension point is used for registering marker update strategies with marker annotation models. A resource that is opened in a text editor is associated with a marker annotation model. For each marker attached to the resource this model manages a position that is updated with each change applied to the text in the editor. If the resource is saved, the text in the editor and the position managed for a marker are passed over to the registered marker update strategies. These strategies can then update the marker's attributes based on the text and the position. Marker update strategies are requested to implement the interface org.eclipse.ui.texteditor.IMarkerUpdater. The update strategies can be registered either for a particular marker type or all marker types. The latter by omitting any marker type in the extension.

Since: Release 1.0

<extension point= "org.eclipse.ui.markerUpdaters">
    <updater
        id="org.eclipse.jdt.ui.markerUpdaters.JavaSearchMarkerUpdater"
        class="org.eclipse.jdt.internal.ui.search.JavaSearchMarkerUpdater"

    </updater>
</extension>

This example registers org.eclipse.jdt.internal.ui.search.JavaSearchMarkerUpdater as a marker updater for all markers of the
type org.eclipse.search.searchmarker including all its derived types..

<extension point= "org.eclipse.ui.markerUpdaters">
    <updater
        id="org.eclipse.ui.texteditor.BasicMarkerUpdater">
        class="org.eclipse.ui.texteditor.BasicMarkerUpdater"
