In particular, if any soft references for a component are deleted, then that component's updateReferences() method will be called to update its internal reference information.

Specified by:

getSoftReferences in interface ModelComponent

Overrides:

Parameters:

refs - list to which soft references are appended

updateReferences

May be called by the system if any of the soft references for this component are removed from the the component hierarchy. If called with undo equal to false, this component should then examine its soft references and use ComponentUtils.areConnected() to determine which of them have been disconnected from the hierarchy. Disconnected references should be removed, and sufficient information should be appended to undoInfo to allow this update to be undone if this method is called later with undo equal to true. When undoing an update, the undo information should be removed from the front of undoInfo.

Specified by:

updateReferences in interface ModelComponent

Overrides:

updateReferences in class ModelComponentBase

Parameters:

undo - if true, indicates that the most recent reference update should be undone, using the supplied undo information.

undoInfo - if undo is false, should be used to store information allowing the reference update to be undone. Otherwise, if undo is true, then this supplied information to undo the most recent update.
