public void setCurrentNumber(java.lang.String domain,
                             long value)

Description copied from interface: UniqueNumbersAPI

Set current value for the sequence. Next UniqueNumbersAPI.getCurrentNumber(String) invocation will return value Next UniqueNumbersAPI.getNextNumber(String) invocation will return value + increment

Specified by:

setCurrentNumber in interface UniqueNumbersAPI

Parameters:

domain - sequence identifier

value - value

deleteSequence

public void deleteSequence(java.lang.String domain)

Description copied from interface: UniqueNumbersAPI

Removes sequence with specified identifier

Specified by:

deleteSequence in interface UniqueNumbersAPI

Parameters:

domain - sequence identifier

getDataStore

protected java.lang.String getDataStore(java.lang.String domain)

Override this method if you want to control in what datastore a sequence is created for a particular domain

Parameters:

domain - sequence identifier passed to the interface methods

Returns:

datastore id (by default, the main datastore)

getSequenceName

protected java.lang.String getSequenceName(java.lang.String domain)
