## org.hyperic.util.jdbc
Class IDGeneratorFactory

    java.lang.Object
      org.hyperic.util.jdbc.IDGeneratorFactory

    public class IDGeneratorFactory

extends java.lang.Object

This factory is meant to be the central point of access for IDGenerator objects used by an application. It will hold the single IDGenerator in a private map and reuse it across repeated invocations of getNextId(). It is particularly useful for Entity bean scenarios, where multiple instances of an IDGenerator result in database row contention and SQL timeouts if more than one thread attempts to get a new id from the sequence at the same time.

Constructor Summary

Method Summary
`static long` | `getNextId(java.lang.String ctx, java.lang.String sequenceName, java.lang.String dsName)` Get a new ID from the named sequence, accessible through the named datasource string.
