Method Detail

foreach

public final void foreach(Consumer<E> consumer)
Description copied from interface: EnclosedIterable

size

public final int size()
Specified by:
size in interface EnclosedIterable<E>

isEmpty in interface Sized
Returns:
true if the there is no data behind it.

createListIterator
