Interface WorkspaceSynchronizer.Delegate

Enclosing class:

WorkspaceSynchronizer

public static interface WorkspaceSynchronizer.Delegate

Call-back interface for an object to which a WorkspaceSynchronizer delegates the algorithms for handling different kinds of resource changes.

Every call-back is invoked asynchronously in a read-only transaction on the synchronizer's editing domain. Any model changes that the receiver wishes to make must be scheduled asynchronously, although workspace changes are permitted as the calling thread has the workspace lock. The call-backs are not actually required to handle the resource change; they can defer to the default behaviour.

Method Summary

void	dispose() Disposes me.
boolean	handleResourceChanged(Resource resource) Optionally handles a change to the physical workspace resource behind the specified EMF resource.
boolean	handleResourceDeleted(Resource resource) Optionally handles the deletion of the physical workspace resource behind the specified EMF resource.
boolean	handleResourceMoved(Resource resource, URI newURI) Optionally handles the move of the physical workspace resource behind the specified EMF resource.

Method Detail

handleResourceDeleted

boolean handleResourceDeleted(Resource resource)

Optionally handles the deletion of the physical workspace resource behind the specified EMF resource.

Parameters:

resource - a resource whose storage has been deleted

Returns:

true if I handled the resource deletion; false to defer to the workspace synchronizer's default algorithm

handleResourceMoved

boolean handleResourceMoved(Resource resource,
                            URI newURI)

Optionally handles the move of the physical workspace resource behind the specified EMF resource. Both in-place renames of a resource and relocations of a resource to another container are considered as moves.

Parameters:

resource - a resource whose storage has been moved

newURI - the new URI of the moved resource

Returns:

true if I handled the resource deletion; false to defer to the workspace synchronizer's default algorithm

handleResourceChanged

boolean handleResourceChanged(Resource resource)

Optionally handles a change to the physical workspace resource behind the specified EMF resource.

Parameters:

resource - a resource whose storage has been changed

Returns:

true if I handled the resource change; false to defer to the workspace synchronizer's default algorithm

dispose

void dispose()

Disposes me. This is called by the synchronizer when it is disposed.
