Method Detail

generate

Object generate()

Returns a unique id across the network, including those generated by generateFor(Class) method. For e.g. if generateFor has already generated id "1", this method will not return "1" anymore. For a single JVM server, this method would just send back an Atomically incremented counter.

Returns:

A unique id.

generateFor

Object generateFor(Class klass)

Returns a unique id across the network, including those generated by generate() method. For e.g. if generate has already generated id "1", this method will not return "1" anymore. For a single JVM server, this method would just send back an Atomically incremented counter.

Parameters:

klass - The class for which this method is being generated. The generator implementation can then probably put in a suffix of identification for generated id's.

Returns:

A unique id.
