public abstract class AbstractLongSet extends AbstractLongCollection implements Cloneable, LongSet
An abstract class providing basic methods for sets implementing a type-specific interface.Note that the type-specific
Set
interface adds a type-specificremove()
method, as it is no longer harmful for subclasses. Thus, concrete subclasses of this class must implementremove()
(therem()
implementation of this class just delegates toremove()
).

iterator
public abstract LongIterator iterator()
Description copied from interface:LongCollection
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

equals
public boolean equals(Object o)

hashCode
public int hashCode()
Returns a hash code for this set. The hash code of a set is computed by summing the hash codes of its elements.
-
remove
public boolean remove(long k)
Removes an element from this set.Note that the corresponding method of a type-specific collection is
rem()
. This unfortunate situation is caused by the clash with the similarly named index-based method in theList
interface. Delegates to the type-specificrem()
method implemented by type-specific abstractCollection
superclass.- Specified by:

Collection.remove(Object)

rem
@Deprecated public boolean rem(long k)
Deprecated.Please useremove()
instead.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()
.This implementation iterates over the elements in the collection, looking for the specified element and tries to remove it. Delegates to the type-specific
remove()
method specified in the type-specificSet
interface.- Specified by:
