Method Detail

add

public boolean add(long k)

Description copied from interface: LongCollection

Ensures that this collection contains the specified element (optional operation).

Specified by:

add in interface LongCollection

See Also:

Collection.add(Object)

contains

public boolean contains(long k)

Description copied from interface: LongCollection

Returns true if this collection contains the specified element.

Specified by:

contains in interface LongCollection

See Also:

Collection.contains(Object)

rem

public boolean rem(long k)

Description copied from interface: LongCollection

Removes a single instance of the specified element from this collection, if it is present (optional operation).

Note that this method should be called remove(), but the clash with the similarly named index-based method in the List interface forces us to use a distinguished name. For simplicity, the set interfaces reinstates remove().

Specified by:

rem in interface LongCollection

See Also:

Collection.remove(Object)

size

public int size()

Specified by:

size in interface Collection<Long>

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface Collection<Long>

toLongArray

public long[] toLongArray()

Description copied from interface: LongCollection

Returns a primitive type array containing the items of this collection.

Specified by:

toLongArray in interface LongCollection

Returns:

a primitive type array containing the items of this collection.

See Also:

Collection.toArray()

toArray

public Object[] toArray()

Specified by:

toArray in interface Collection<Long>

toLongArray

@Deprecated
public long[] toLongArray(long[] a)

Deprecated.

Description copied from interface: LongCollection

Returns a primitive type array containing the items of this collection.

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:

toLongArray in interface LongCollection

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.

See Also:

Collection.toArray(Object[])

toArray

public long[] toArray(long[] a)

Description copied from interface: LongCollection

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

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 LongCollection

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.

See Also:

Collection.toArray(Object[])

addAll

public boolean addAll(LongCollection c)

Description copied from interface: LongCollection

Adds all elements of the given type-specific collection to this collection.

Specified by:

addAll in interface LongCollection

Parameters:

c - a type-specific collection.

Returns:

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

See Also:

Collection.addAll(Collection)

containsAll

public boolean containsAll(LongCollection c)

Description copied from interface: LongCollection

Checks whether this collection contains all elements from the given type-specific collection.

Specified by:

containsAll in interface LongCollection

Parameters:

c - a type-specific collection.

Returns:

true if this collection contains all elements of the argument.

See Also:

Collection.containsAll(Collection)

removeAll

public boolean removeAll(LongCollection c)

Description copied from interface: LongCollection

Remove from this collection all elements in the given type-specific collection.

Specified by:

removeAll in interface LongCollection

Parameters:

c - a type-specific collection.

Returns:

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

See Also:

Collection.removeAll(Collection)

removeIf

public boolean removeIf(LongPredicate filter)

Description copied from interface: LongCollection

Remove from this collection all elements which satisfy the given predicate.

Specified by:

removeIf in interface LongCollection

Parameters:

filter - a predicate which returns true for elements to be removed.

Returns:

true if any elements were removed.

See Also:

Collection.removeIf(java.util.function.Predicate)

retainAll

public boolean retainAll(LongCollection c)

Description copied from interface: LongCollection

Retains in this collection only elements from the given type-specific collection.

Specified by:

retainAll in interface LongCollection

Parameters:

c - a type-specific collection.

Returns:

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

See Also:

Collection.retainAll(Collection)

toArray

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

Specified by:

iterator

public LongIterator iterator()

Description copied from interface: LongCollection

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.
