Class EnumCombinationIterator<E extends Enum<E>>

java.lang.Object
org.evrete.util.EnumCombinationIterator<E>
Type Parameters:
E - the type of the enum
All Implemented Interfaces:
Iterator<E[]>
public class EnumCombinationIterator<E extends Enum<E>> extends Object implements Iterator<E[]>
Provides an iterator for all combinations of enum values for a given enum class E inside a given array E[]. The total count is thus pow(enum length, array size). The iterator reuses the given array rather than creating a new one for each iteration, leading to faster performance and reduced memory footprint.
