init

public void init()

Description copied from interface: UIDSequencer

Init Sequencer

dispose

public void dispose()

Description copied from interface: UIDSequencer

Cleanup callback

initSequence

public void initSequence(String key,
                         long id)

Description copied from interface: UIDSequencer

Initializes the sequencer with the given key to at least the given long id.

A sequence can only be incremented, so if its current id is greater than the given id the sequence won't be decremented to reach the given id.

Specified by:

initSequence in interface UIDSequencer

Overrides:

initSequence in class AbstractUIDSequencer

getNextLong

public long getNextLong(String key)

Description copied from interface: UIDSequencer

Extends UIDSequencer.getNext(java.lang.String) to return a long value. This method is compatible with getNext in the integer range.

getNextBlock

public List<Long> getNextBlock(String key,
                               int blockSize)

Description copied from interface: UIDSequencer

Returns a block containing blockSize sequences.
