public interface IterableWithSize<E> extends Iterable<E>
Represents read only collection of semantical elements - it does not guarantee that next iteration will return the same instance of the object. Or in other words: the instance returned in next iteration can be different instance of object, but it has to represent the semantically same element from problem domain. So the condition (iterator().next() == iterator().next()) is not guaranteed to always evaluate to TRUE
Since:
3.9.0

  • Method Summary

    Modifier and Type
    Method
    Description
    void
    addAllTo(Collection<? super E> collection)
     
    boolean
    isEmpty()
     
    int
    size()
     
    E[]
    toArray(E[] a)
    Iterating over array is faster, when checking for concurrent modification is not needed.
    ArrayList<E>
    toArrayList()
    Returns new ArrayList containing the same elements, so modifying the returned list does not modify the original collection.

    Methods inherited from interface java.lang.Iterable

    forEach, iterator, spliterator
