Method Detail

size

public int size()

Specified by:

size in interface Collection<K>

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface Collection<K>

contains

public boolean contains(Object o)

Specified by:

contains in interface Collection<K>

iterator

public ObjectIterator<K> iterator()

Description copied from interface: ReferenceCollection

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.

Specified by:

iterator in interface ObjectIterable<K>

Specified by:

iterator in interface ReferenceCollection<K>

Specified by:

iterator in interface Iterable<K>

Specified by:

iterator in interface Collection<K>

Returns:

a type-specific iterator on the elements of this collection.

objectIterator

@Deprecated
public ObjectIterator<K> objectIterator()

Deprecated.

Description copied from interface: ReferenceCollection

Returns a type-specific iterator on this elements of this collection.

Specified by:

objectIterator in interface ReferenceCollection<K>

add

public boolean add(K k)

Specified by:

add in interface Collection<K>

remove

public boolean remove(Object ok)

Specified by:

remove in interface Collection<K>

addAll

public boolean addAll(Collection<? extends K> c)

Specified by:

addAll in interface Collection<K>

containsAll

public boolean containsAll(Collection<?> c)

Specified by:

containsAll in interface Collection<K>

removeAll

public boolean removeAll(Collection<?> c)

Specified by:

removeAll in interface Collection<K>

retainAll

public boolean retainAll(Collection<?> c)

Specified by:

retainAll in interface Collection<K>

clear

public void clear()

Specified by:

clear in interface Collection<K>

toString

public String toString()

Overrides:

toString in class Object

toArray

public <T> T[] toArray(T[] a)

Description copied from interface: ReferenceCollection

Returns an containing the items of this collection; the runtime type of the returned array is that of the specified array.

Warning: Note that, contrarily to Collection.toArray(Object[]), this methods just writes all elements of this collection: no special value will be added after the last one.

Specified by:

toArray in interface ReferenceCollection<K>

Specified by:

toArray in interface Collection<K>

Parameters:

a - if this array is big enough, it will be used to store this collection.

Returns:

a primitive type array containing the items of this collection.
