OperationGraphManager
keeps track of all operation graphs that are currently open for editing in an InterchangeView
. An operation graph controller can check with the operation graph manager if a change initiated by the user is allowed, or if it can cause conflicts with other, unsaved changes made to other graphs. The OperationGraphManager
instance to use for a given InterchangeView
is retrieved by calling {@link #getManager(InterchangeView) getManager}.
