public final class Sequencer

extends SimpleXMLObject

Sequencer is a system-level sequencer for creating auto-incrementing values. It operates in a similar fashion to how Interbase performs auto-incrementing. You use the methods to create and retrieve values from named sequences. These sequences don't have to be explicitly associated with any particular Collection, which allows them to be shared between Collections, or even Databases and Servers for that matter.
