Class SliceBeforeIterator<E>

java.lang.Object

net.sf.rubycollect4j.iter.SliceBeforeIterator<E>

Type Parameters:

E - the type of the elements

All Implemented Interfaces:

java.util.Iterator<RubyArray<E>>

public final class SliceBeforeIterator<E>
extends java.lang.Object
implements java.util.Iterator<RubyArray<E>>

SliceBeforeIterator iterates all elements by slicing elements into different parts. It performs each slicing when any element is true returned by the block or matched by the pattern.
