public class DefaultProgrammerManager
extends PropertyChangeSupport
implements AddressedProgrammerManager, GlobalProgrammerManager

Provides a very basic implementation of a programmer manager by providing a union of the AddressedProgrammerManager and GlobalProgrammerManager interfaces.

This implementation requires a service-mode Programmer at construction time and returns that Programmer for all global programming mode requests. This implementation of AddressedProgrammerManager always returns null for Op Mode, or addressed programmer requests, indicating there is no programmer of that type.
