Examples of org.eclipse.core.commands.State

org.eclipse.core.commands.State

A piece of state information that can be shared between objects, and might be persisted between sessions. This can be used for commands that toggle between two states and wish to pass this state information between different handlers.

This state object can either be used as a single state object shared between several commands, or one state object per command -- depending on the needs of the application.

Clients may instantiate or extend this class.
