addAll

public boolean addAll(java.util.Collection<? extends java.lang.Integer> c)
Description copied from class: AbstractIntCollection
Adds all elements of the given collection to this collection.

Specified by:
addAll in interface java.util.Collection<java.lang.Integer>
Specified by:
addAll in interface java.util.Set<java.lang.Integer>
Overrides:
addAll in class AbstractIntCollection

Overrides:
removeAll in class AbstractIntCollection
Parameters:
c - a collection.
Returns:
true if this collection changed as a result of the call.

retainAll

public boolean retainAll(java.util.Collection<?> c)
Description copied from class: AbstractIntCollection
Retains in this collection only elements from the given collection.

Specified by:
retainAll in interface java.util.Collection<java.lang.Integer>
Specified by:
retainAll in interface java.util.Set<java.lang.Integer>
Overrides:
retainAll in class AbstractIntCollection
Parameters:
c - a collection.
Returns:
true if this collection changed as a result of the call.

toIntArray

public int[] toIntArray()
Description copied from interface: IntCollection
Returns a primitive type array containing the items of this collection.

Specified by:
toIntArray in interface IntCollection
Overrides:
toIntArray in class AbstractIntCollection
Returns:
a primitive type array containing the items of this collection.
See Also:
Collection.toArray()

addAll

public boolean addAll(IntCollection c)
Description copied from class: AbstractIntCollection
Adds all elements of the given type-specific collection to this collection.

Specified by:
addAll in interface IntCollection
Overrides:
addAll in class AbstractIntCollection
Parameters:
c - a type-specific collection.
Returns:
true if this collection changed as a result of the call.
See Also:
Collection.addAll(Collection)

removeAll

public boolean removeAll(IntCollection c)
Description copied from class: AbstractIntCollection
Remove from this collection all elements in the given type-specific collection.

Specified by:
removeAll in interface IntCollection
Overrides:

public boolean retainAll(IntCollection c)
Description copied from class: AbstractIntCollection
Retains in this collection only elements from the given type-specific collection.

Specified by:
retainAll in interface IntCollection
Overrides:
retainAll in class AbstractIntCollection
Parameters:
c - a type-specific collection.
Returns:
true if this collection changed as a result of the call.
See Also:
Collection.retainAll(Collection)

iterator

public IntListIterator iterator()
Description copied from interface: IntCollection
Returns a type-specific iterator on the elements of this collection.

Note that this specification strengthens the one given in Iterable.iterator(), which was already strengthened in the corresponding type-specific class, but was weakened by the fact that this interface extends Collection.

iterator in interface IntIterable
Specified by:
iterator in interface IntSet
Specified by:
iterator in interface java.lang.Iterable<java.lang.Integer>
Specified by:
iterator in interface java.util.Collection<java.lang.Integer>
Specified by:
iterator in interface java.util.Set<java.lang.Integer>
Specified by:
iterator in class AbstractIntSet
Returns:
a type-specific iterator on the elements of this collection.

size

public int size()
Specified by:
size in interface java.util.Collection<java.lang.Integer>
Specified by:
size in interface java.util.Set<java.lang.Integer>

clone

public java.lang.Object clone()
Overrides:
clone in class java.lang.Object
