public abstract class AbstractByteCollection extends java.util.AbstractCollection<java.lang.Byte> implements ByteCollection
An abstract class providing basic methods for collections implementing a type-specific interface.In particular, this class provide
iterator()
,add()
,remove(Object)
andcontains(Object)
methods that just call the type-specific counterpart.Warning: Because of a name clash between the list and collection interfaces the type-specific deletion method of a type-specific abstract collection is
rem()
, rather thenremove()
. A subclass must thus overriderem()
, rather thanremove()
, to make all inherited methods work properly.

iterator
public abstract ByteIterator iterator()
Description copied from interface:ByteCollection
Returns a type-specific iterator on the elements of this collection.- Specified by:
iterator
in interfaceByteCollection
- Specified by:
iterator
in interfaceByteIterable
- Specified by:
iterator
in interfacejava.util.Collection<java.lang.Byte>
- Specified by:
iterator
in interfacejava.lang.Iterable<java.lang.Byte>
- Specified by:
iterator
in classjava.util.AbstractCollection<java.lang.Byte>
- Returns:
- a type-specific iterator on the elements of this collection.
- See Also:
Iterable.iterator()
-
add
public boolean add(byte k)
Ensures that this collection contains the specified element (optional operation).- Specified by:
add
in interfaceByteCollection
- See Also:
Collection.add(Object)
- Implementation Specification:
- This implementation always throws an
UnsupportedOperationException
.
-
contains
public boolean contains(byte k)
Returnstrue
if this collection contains the specified element.- Specified by:
contains
in interfaceByteCollection
- See Also:
Collection.contains(Object)
- Implementation Specification:
- This implementation iterates over the elements in the collection, looking for the specified element.
-
rem
public boolean rem(byte k)
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)
- Implementation Specification:
- This implementation iterates over the elements in the collection, looking for the specified element and tries to remove it.

Description copied from interface:ByteCollection
Returns a primitive type array containing the items of this collection.- Specified by:
