public class ByteArraySet extends AbstractByteSet implements Serializable, Cloneable
The main purpose of this implementation is that of wrapping cleanly the brute-force approach to the storage of a very small number of items: just put them into an array and scan linearly to find an item.
| Constructor and Description |
|---|
ByteArraySet()
Creates a new empty array set.
|
ByteArraySet(byte[] a)
Creates a new array set using the given backing array.
|
ByteArraySet(byte[] a,
int size)
Creates a new array set using the given backing array and the given number of elements of the array.
|
ByteArraySet(ByteCollection c)
Creates a new array set copying the contents of a given collection.
|
ByteArraySet(Collection<? extends Byte> c)
Creates a new array set copying the contents of a given set.
|
ByteArraySet(int capacity)
Creates a new empty array set of given initial capacity.

It is responsibility of the caller that the elements of a are distinct.

It is responsibility of the caller that the first size elements of a are distinct.
a - the backing array.size - the number of valid elements in a.public ByteIterator iterator()
ByteCollectionNote 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.

ByteSetNote that the corresponding method of the type-specific collection is rem().
This unfortunate situation is caused by the clash
with the similarly named index-based method in the List interface.

This method performs a deep copy of this hash set; the data stored in the set, however, is not cloned. Note that this makes a difference only for object keys.
