public interface SequenceGenerator

A generator for datastore sequences. This can be used for assigning sequences to application identity primary key fields.

Method Summary

boolean	ensureCapacity(int count) Ensures that this sequence generator has sufficient capacity readily available to provide count new sequence values.
Number	getNext() Deprecated. Use next() instead. Implementations should ensure that the value returned is within the range of a long, and does not have a decimal part.
long	next() Returns the next long in the sequence.
