Class PatternStateIterator

java.lang.Object

org.colomoto.biolqm.helper.state.PatternStateIterator

All Implemented Interfaces:

Iterator<byte[]>

public class PatternStateIterator
extends Object
implements Iterator<byte[]>

Iterator over all states covered by a state pattern. This iterator expands a pattern into individual states, it supports multi-valued components. All generated states use the same memory slot, users of this iterator should clone them as needed.
