java.lang.Objectorg.apache.commons.collections.primitives.AbstractIntCollection
Abstract base class for IntCollections.

and size(). Mutable subclasses
should also override add(int) and
IntIterator.remove.
All other methods have at least some base implementation
derived from these. Subclasses may choose to override
these methods to provide a more efficient implementation.

public abstract IntIterator iterator()
IntCollectioniterator over all my elements.
This base interface places no constraints on the order
in which the elements are returned by the returned iterator.

IntCollection
size in interface IntCollectionpublic boolean add(int element)
add in interface IntCollectionelement - the value whose presence within me is to be ensured
true iff I changed as a result of this callpublic boolean addAll(IntCollection c)
IntCollectionAdds all of the elements in the
specified collection to me (optional operation).
addAll in interface IntCollectionc - the collection of elements whose presence within me is to
be ensured
true iff I changed as a result of this callpublic void clear()
IntCollectionempty after this
method successfully returns.

IntCollectiontrue iff I contain
the specified element.
contains in interface IntCollectionelement - the value whose presence within me is to be tested
true iff I contain the specified elementpublic boolean containsAll(IntCollection c)
IntCollectiontrue iff I contain
all of the elements in the given collection.
containsAll in interface IntCollectionc - the collection of elements whose presence within me is to
be tested
true iff I contain the all the specified elementspublic boolean isEmpty()
IntCollectiontrue iff I contain no elements.
isEmpty in interface IntCollectiontrue iff I contain no elements.public boolean removeElement(int element)
IntCollection
removeElement in interface IntCollectionelement - the element to remove, if present
true iff I contained the specified element,
in other words, iff I changed as a result of this callpublic boolean removeAll(IntCollection c)
IntCollection
removeAll in interface IntCollectionc - the collection of elements to remove
true iff I contained the at least one of the
specified elements, in other words, returns true
iff I changed as a result of this callpublic boolean retainAll(IntCollection c)
IntCollection
retainAll in interface IntCollectionc - the collection of elements to retain
true iff I changed as a result
of this callpublic int[] toArray()
IntCollectionsize.
The returned array will be independent of me,
so that callers may modify that
returned array without modifying this collection.
When I guarantee the order in which
elements are returned by an iterator,
the returned array will contain elements in the
same order.
toArray in interface IntCollectionpublic int[] toArray(int[] a)
IntCollectioniterator,
the returned array will contain elements in the
same order.
toArray in interface IntCollectiona - an array that may be used to contain the elements
