org.cfeclipse.cfml.editors.decoration.DecorationSupport

Support class used by text editors to draw and update decorations on the source viewer and its rulers. An instance of this class is independent of a certain editor and must be configured with the needed preference keys and helper objects before it can be used.

Once configured, an instance may be installed (see {@link #install(IPreferenceStore) install}) on a preference store, from then on monitoring the configured preference settings and changing the respective decorations. Calling {@link #uninstall() uninstall} will unregister thelisteners with the preferences store and must be called before changing the preference store by another call to install.
{@link #dispose() dispose} will uninstall the support and remove anydecorations from the viewer. It is okay to reuse a SourceViewerDecorationSupport instance after disposing it.

SourceViewerDecorationSupport can draw the following decorations:

matching character highlighting,
current line highlighting,
print margin, and
annotations.

Annotations are managed for the overview ruler and also drawn onto the text widget by an {@link org.eclipse.jface.text.source.AnnotationPainter AnnotationPainter}instance.

Subclasses may add decorations but should adhere to the lifecyle described above.
