Interface ByteCollection

All Superinterfaces:

Collection

All Known Subinterfaces:

ByteList, ByteSet, ByteSortedSet

All Known Implementing Classes:

public interface ByteCollection

extends Collection

A type-specific Collection; provides some additional methods that use polymorphism to reduce type juggling.

Note that iterators provided by classes implementing this interface must be type specific.

See Also:

Collection

Method Summary

boolean	add(byte key)
boolean	addAll(ByteCollection c)
ByteIterator	byteIterator() Returns a type-specific iterator on the collection.
boolean	contains(byte key)
boolean	containsAll(ByteCollection c)
boolean	rem(byte key) 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	removeAll(ByteCollection c)
boolean	retainAll(ByteCollection c)
byte[]	toArray(byte[] a) Builds a primitive type array containing the items of this collection.
byte[]	toByteArray() Returns a primitive type array containing the items of this collection.
byte[]	toByteArray(byte[] a) Builds a primitive type array containing the items of this collection.

Method Detail

byteIterator

public ByteIterator byteIterator()

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.

Since:

2.51

Collection.iterator()

contains

public boolean contains(byte key)

See Also:

Collection.contains(Object)

toByteArray

public byte[] toByteArray()

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

Returns:

a primitive type array containing the items of this collection.

See Also:

Collection.toArray()

toByteArray

public byte[] toByteArray(byte[] a)

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

Parameters:

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

Returns:

a primitive type array containing the items of this collection.

See Also:

Collection.toArray(Object[])

toArray

public byte[] toArray(byte[] a)

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

Parameters:

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

Returns:

a primitive type array containing the items of this collection.

See Also:

Collection.toArray(Object[])

add

public boolean add(byte key)

See Also:

Collection.add(Object)

rem

public boolean rem(byte key)

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().

See Also:

Collection.remove(Object)

addAll

public boolean addAll(ByteCollection c)

See Also:

Collection.addAll(Collection)

containsAll

public boolean containsAll(ByteCollection c)

See Also:

Collection.containsAll(Collection)

removeAll

public boolean removeAll(ByteCollection c)

See Also:

Collection.removeAll(Collection)

retainAll

public boolean retainAll(ByteCollection c)

See Also:

Collection.retainAll(Collection)
