Class StripedLongSequenceGenerator

java.lang.Object

io.rainfall.generator.StripedLongSequenceGenerator

All Implemented Interfaces:

SequenceGenerator

public class StripedLongSequenceGenerator
extends Object
implements SequenceGenerator

Striped SequenceGenerator that divides the range of generated sequences into instanceCount sub-ranges.

This generator is useful in scenarios where multiple independent JVMs are being used and need to generate unique sequences as each JVM will get its own sub-range to generate from, provided that each JVM supplies a distinct index with the given StripedLongSequenceGenerator.InstanceIndexSupplier.

Indices supplied by StripedLongSequenceGenerator.InstanceIndexSupplier must be in the range 0 to (instanceCount - 1).
