Method Detail

size

public int size()

Specified by:

size in interface Collection<Long>

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface Collection<Long>

contains

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.

Specified by:

iterator in interface LongCollection

Specified by:

iterator in interface LongIterable

Specified by:

iterator in interface Iterable<Long>

Specified by:

iterator in interface Collection<Long>

Returns:

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

longIterator

@Deprecated

toArray

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

Description copied from interface: LongCollection

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 LongCollection

Specified by:

toArray in interface Collection<Long>

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 Object[] toArray()

Specified by:

toArray 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()

toLongArray

public long[] toLongArray(long[] a)

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.

toArray

public long[] toArray(long[] a)

Description copied from interface: LongCollection

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

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[])

rem

public boolean rem(long k)

Description copied from interface: LongCollection

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().
