All Implemented Interfaces:

ByteCollection, ByteIterable, Iterable<Byte>, Collection<Byte>

Direct Known Subclasses:

AbstractByteList, AbstractByteSet, ByteCollections.EmptyCollection

public abstract class AbstractByteCollection
extends Object
implements ByteCollection

An abstract class providing basic methods for collections implementing a type-specific interface.

In particular, this class provide iterator(), add(), remove(Object) and contains(Object) methods that just call the type-specific counterpart.

Method Summary

boolean	add(byte k)
boolean	add(Byte o) Delegates to the corresponding type-specific method.
boolean	addAll(ByteCollection c) Adds all elements of the given type-specific collection to this collection.
boolean	addAll(Collection<? extends Byte> c) Adds all elements of the given collection to this collection.
ByteIterator	byteIterator() Deprecated.
void	clear()
boolean	contains(Object o) Delegates to the corresponding type-specific method.
boolean	containsAll(ByteCollection c) Checks whether this collection contains all elements from the given type-specific collection.
boolean	containsAll(Collection<?> c) Checks whether this collection contains all elements from the given collection.
boolean	isEmpty()
abstract ByteIterator	iterator() Returns a type-specific iterator on the elements of this collection.
boolean	rem(byte k) 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.
boolean	rem(Object o) Delegates to the corresponding type-specific method.
boolean	remove(Object ok)
boolean	removeAll(ByteCollection c) Remove from this collection all elements in the given type-specific collection.
boolean	removeAll(Collection<?> c) Remove from this collection all elements in the given collection.
boolean	retainAll(ByteCollection c) Retains in this collection only elements from the given type-specific collection.
boolean	retainAll(Collection<?> c) Retains in this collection only elements from the given collection.
Object[]	toArray()
byte[]	toArray(byte[] a) Returns a primitive type array containing the items of this collection.
<T> T[]	toArray(T[] a) Returns an containing the items of this collection; the runtime type of the returned array is that of the specified array.
byte[]	toByteArray() Returns a primitive type array containing the items of this collection.
byte[]	toByteArray(byte[] a) Returns a primitive type array containing the items of this collection.
String	toString()

Method Detail

toArray

public byte[] toArray(byte[] a)

Description copied from interface: ByteCollection

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:

toArray in interface ByteCollection

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[])

toByteArray

public byte[] toByteArray()

Description copied from interface: ByteCollection

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

Specified by:

toByteArray in interface ByteCollection

Returns:

a primitive type array containing the items of this collection.

See Also:

Collection.toArray()

toByteArray

public byte[] toByteArray(byte[] a)

Description copied from interface: ByteCollection

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:

toByteArray in interface ByteCollection

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(byte k)

Description copied from interface: ByteCollection

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 ByteCollection

See Also:

Collection.remove(Object)

addAll

public boolean addAll(ByteCollection c)

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

Specified by:

addAll in interface ByteCollection

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(ByteCollection c)

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

Specified by:

containsAll in interface ByteCollection

Parameters:

c - a type-specific collection.

Returns:

true if this collection contains all elements of the argument.

See Also:

Collection.containsAll(Collection)

retainAll

public boolean retainAll(ByteCollection c)

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

Specified by:

retainAll in interface ByteCollection

Parameters:

c - a type-specific collection.

Returns:

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

See Also:

Collection.retainAll(Collection)

removeAll

public boolean removeAll(ByteCollection c)

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

Specified by:

removeAll in interface ByteCollection

Parameters:

c - a type-specific collection.

Returns:

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

See Also:

Collection.removeAll(Collection)

toArray

public Object[] toArray()

Specified by:

toArray in interface Collection<Byte>

toArray

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

Description copied from interface: ByteCollection

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 ByteCollection

Specified by:

toArray in interface Collection<Byte>

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(Collection<? extends Byte> c)

Adds all elements of the given collection to this collection.

Specified by:

addAll in interface Collection<Byte>

Parameters:

c - a collection.

Returns:

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

add

public boolean add(byte k)

Specified by:

add in interface ByteCollection

See Also:

Collection.add(Object)

remove

public boolean remove(Object ok)

Specified by:

remove in interface Collection<Byte>

clear

public void clear()

clear in interface Collection<Byte>

byteIterator

@Deprecated
public ByteIterator byteIterator()

Deprecated.

Delegates to the new covariantly stronger generic method.

Specified by:

byteIterator in interface ByteCollection

See Also:

ByteCollection.iterator()

iterator

public abstract ByteIterator iterator()

Description copied from interface: ByteCollection

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 ByteCollection

Specified by:

iterator in interface ByteIterable

Specified by:

iterator in interface Iterable<Byte>

Specified by:

iterator in interface Collection<Byte>

Returns:

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

add

public boolean add(Byte o)

Delegates to the corresponding type-specific method.

Specified by:

add in interface Collection<Byte>

rem

public boolean rem(Object o)

Delegates to the corresponding type-specific method.

contains

public boolean contains(Object o)

Delegates to the corresponding type-specific method.
