InnerEventDispatcherAdapter

public InnerEventDispatcherAdapter()
Method Detail

isApplicable

public boolean isApplicable(ChangeEvent event)
Description copied from interface: InnerEventDispatcher
This method called for checking either we need to call this visitor for event.

Specified by:
isApplicable in interface InnerEventDispatcher
Parameters:
event - Fired event.
Returns:
Is applicable this visitor for event.

preDispatch

public void preDispatch(ChangeEvent event)
                 throws VetoException
Description copied from interface: InnerEventDispatcher
This method will be called before action on model will be performed. This method could throw VetoException. It should not throw any exception on events about accessing to children ( setting/adding/removing child in parent ). This is because OM doesn't have methods that could be incorrectly used. Only setting incorrect attribute value could throw such exception.

Specified by:
preDispatch in interface InnerEventDispatcher
Parameters:
event - Event that will be fired after OM will be changed. It is not yet happened.
Throws:
VetoException - VetoException Could be thrown if event is rejected by visitor.

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
Parameters:
event - Event that fired by OM after change was performed.

reset

public void reset(ChangeEvent event)
Description copied from interface: InnerEventDispatcher
This method is called when some exception is detected in one of dispatchers. Then all dispatchers that collect some information on preDispatch stage can clear this information. Suggested use - when one of inner dispatchers throws VetoException then all diaspatchers need to clean internal state, because postDispatch will never be called.

Specified by:
reset in interface InnerEventDispatcher
Parameters:
event - Event that fired by OM after change was performed.
