Method Detail

processChangeEvent

public void processChangeEvent(ChangeEvent evt)

Description copied from interface: ChangeListener

This method is called when a change event has occurred. The information about the change is contained in the argument event. The argument event however should not be used by the listener. The listener should retrieve any information it needs from the event and then release it.

Specified by:

processChangeEvent in interface ChangeListener

setRepositorySize

public void setRepositorySize(int n)

Initialization method to set the capacity of the repository. This method should only be called once before the components is used. Attempts to call it more than once result in a configuration report being generated.

Overrides:

setRepositorySize in class EventRepository

latestChangeEvent

public ChangeEvent latestChangeEvent()

Type-safe iterator. Wraps latestEvent method in super class adding cast from Object to ChangeEvent.

previousChangeEvent

public ChangeEvent previousChangeEvent()

Type-safe iterator. Wraps previousEvent method in super class adding cast from Object to ChangeEvent.
