java.lang.Object

org.apache.sshd.common.util.helper.LazyIterablesConcatenator<T>

Type Parameters:

T - Type of element being iterared

All Implemented Interfaces:

Iterable<T>

public class LazyIterablesConcatenator<T>
extends Object
implements Iterable<T>

Creates a "smooth" wrapping Iterable using several underlying ones to provide the values. The "lazy" denomination is due to the fact that no iterable is consulted until the one(s) before it have been fully exhausted.
