Class ChunkIterable<E,K>

java.lang.Object

net.sf.rubycollect4j.iter.ChunkIterable<E,K>

Type Parameters:

E - the type of the elements

K - the type of the transformed elements

All Implemented Interfaces:

java.lang.Iterable<java.util.Map.Entry<K,RubyArray<E>>>

public final class ChunkIterable<E,K>
extends java.lang.Object
implements java.lang.Iterable<java.util.Map.Entry<K,RubyArray<E>>>

ChunkIterable transforms elements first, and then puts the original elements together if elements which are next to each others have the same transformed value. Chucked elements are placed into an Entry which uses transformed value as key and a RubyArray of elements as value.
