Parameters:

entryMap - a map instance to be used as internal map.

Throws:

InstantiationException - is thrown if registry could not be instantiated.

Method Detail

notifySynchronization

public void notifySynchronization()

Informs the controller registry that the synchronization with the external controller configuration registry was done.

Specified by:

notifySynchronization in interface SynchronizableRegistry<KEY,ENTRY extends Identifiable<KEY>>

isInitiallySynchronized

public boolean isInitiallySynchronized()

Method returns the initial synchronization state.

Specified by:

isInitiallySynchronized in interface SynchronizableRegistry<KEY,ENTRY extends Identifiable<KEY>>

Returns:

true if the the initial synchronization is done.

getLastSynchronizationTimestamp

public long getLastSynchronizationTimestamp()
                                     throws NotAvailableException

Method returns the timestamp of the last synchronization.

Specified by:

getLastSynchronizationTimestamp in interface SynchronizableRegistry<KEY,ENTRY extends Identifiable<KEY>>

Returns:

the timestamp in milliseconds.

Throws:

NotAvailableException - is thrown in case the synchronization was never performed.
