Method Detail

add
public boolean add(byte k)
Description copied from interface:ByteCollection
Ensures that this collection contains the specified element (optional operation).- Specified by:
add
in interfaceByteCollection
- See Also:
Collection.add(Object)
-
rem
public boolean rem(byte k)
Description copied from interface:ByteCollection
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 theList
interface forces us to use a distinguished name. For simplicity, the set interfaces reinstatesremove()
.- Specified by:
rem
in interfaceByteCollection
- See Also:
Collection.remove(Object)
-
size
public int size()
- Specified by:
size
in interfaceCollection<Byte>
-
isEmpty
public boolean isEmpty()
- Specified by:
isEmpty
in interfaceCollection<Byte>
-
contains
public boolean contains(byte o)
Description copied from interface:ByteCollection
Returnstrue
if this collection contains the specified element.- Specified by:
contains
in interfaceByteCollection
- See Also:
Collection.contains(Object)
-
iterator
public 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 extendsCollection
.- Specified by:
iterator
in interfaceByteCollection
- Specified by:
iterator
in interfaceByteIterable
- Specified by:
iterator
in interfaceCollection<Byte>
- Specified by:
iterator
