org.eclipse.jface.text.link.LinkedModeModel
The model for linked mode, umbrellas several {@link LinkedPositionGroup}s. Once installed, the model propagates any changes to a position to all its siblings in the same position group.
Setting up a model consists of first adding LinkedPositionGroups to it, and then installing the model by either calling {@link #forceInstall()} or{@link #tryInstall()}. After installing the model, it becomes sealed and no more groups may be added.

If a document change occurs that would modify more than one position group or that would invalidate the disjointness requirement of the positions, the model is torn down and all positions are deleted. The same happens upon calling {@link #exit(int)}.

Nesting

A LinkedModeModel may be nested into another model. This happens when installing a model the positions of which all fit into a single position in a parent model that has previously been installed on the same document(s).

Clients may instantiate instances of this class.
@since 3.0 @noextend This class is not intended to be subclassed by clients.
