Method Detail

public boolean isApplicable(ChangeEvent event)
Description copied from interface: InnerEventDispatcher

preDispatch

public void preDispatch(ChangeEvent event)
Description copied from interface: InnerEventDispatcher
This method will be called before action on model will be performed. This method could throw VetoException.

event - Event that will be fired after OM will be changed. It is not yet happened.

postDispatch

public void postDispatch(ChangeEvent event)
Description copied from interface: InnerEventDispatcher
This method will be called after action on model was performed. It could perform additional changes in OM based on event information. F.e. it could change name of attribute that reference to some entity by name and this name was changed.

Specified by:
postDispatch in interface InnerEventDispatcher
Overrides:
postDispatch in class InnerEventDispatcherAdapter
Parameters:
event - Event that fired by OM after change was performed.
