delta

public FileListCacheValueDelta delta()

Description copied from interface: DeltaAware

Extracts changes made to implementations, in an efficient format that can easily and cheaply be serialized and deserialized. This method will only be called once for each changeset as it is assumed that any implementation's internal changelog is wiped and reset after generating and submitting the delta to the caller.

Specified by:

delta in interface DeltaAware

Returns:

an instance of Delta

commit

public void commit()

Description copied from interface: DeltaAware

Indicate that all deltas collected to date has been extracted (via a call to DeltaAware.delta()) and can be discarded. Often used as an optimization if the delta isn't really needed, but the cleaning and resetting of internal state is desirable.

Specified by:

commit in interface DeltaAware
