Method Detail

add

public boolean add(int k)

Specified by:

add in interface IntCollection

Overrides:

add in class AbstractIntCollection

contains

public boolean contains(int k)

Specified by:

contains in interface IntCollection

See Also:

Collection.contains(Object)

addAll

public boolean addAll(List l)

addAll

public boolean addAll(Collection c)

Description copied from class: AbstractIntCollection

Adds all elements of the given collection to this collection.

Specified by:

addAll in interface Set

Overrides:

addAll in class AbstractIntCollection

Parameters:

c - a collection.

Returns:

true if this collection changed as a result of the call.

removeAll

public boolean removeAll(Collection c)

Description copied from class: AbstractIntCollection

Remove from this collection all elements in the given collection. If the collection is an instance of this class, it uses faster iterators.

Specified by:

removeAll in interface Set

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(Collection c)

Description copied from class: AbstractIntCollection

Retains in this collection only elements from the given collection.

Specified by:

retainAll in interface Set

Overrides:

retainAll in class AbstractIntCollection

Parameters:

c - a collection.

Returns:

true if this collection changed as a result of the call.

addAll

public boolean addAll(IntList l)

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.

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:

removeAll in class AbstractIntCollection

Parameters:

c - a type-specific collection.

Returns:

true if this collection changed as a result of the call.

retainAll

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.

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

intIterator

public IntIterator intIterator()

Description copied from interface: IntCollection

Returns a type-specific iterator on the collection.

The iterator returned by the Collection.iterator() method and by this method are identical; however, using this method you can save a type casting.

Specified by:

intIterator in interface IntCollection

See Also:

Collection.iterator()

size

public int size()

Specified by:

size in interface Set

clone

public Object clone()
