has been called and before the actual
remove is done. In case this method returns true
, the
operation will be cancelled by the Graphiti framework by throwing an

that causes am EMF revert of the
operation.
Implementing classes might e.g. set a flag in
preRemove(IRemoveContext)
as cancellation indication and check
that that flag here.
