Package org.wildfly.common.iteration

Class CompositeIterable<T>

java.lang.Object

org.wildfly.common.iteration.CompositeIterable<T>

All Implemented Interfaces:

Iterable<T>

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

Used for iterating over an series of iterables, thus avoiding the need to allocate/populate a new list containing all elements. More efficient than the alternative when the number of iterables is arbitrary and small relative to the size of each iterable.
