Class CompositeIterable<T>

  • All Implemented Interfaces:
    java.lang.Iterable<T>
    public class CompositeIterable<T>
extends java.lang.Object
implements java.lang.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.
