public abstract class AbstractLongSet extends AbstractLongCollection implements Cloneable, LongSet
Note that the type-specific Set interface adds a type-specific
remove() method, as it is no longer harmful for subclasses. Thus,
concrete subclasses of this class must implement remove() (the
rem() implementation of this class just delegates to
remove()).

The equals method implements an equivalence relation
on non-null object references:
x, x.equals(x) should return
true.
x and y, x.equals(y)
should return true if and only if
y.equals(x) returns true.
x, y, and z, if
x.equals(y) returns true and
y.equals(z) returns true, then
x.equals(z) should return true.
x and y, multiple invocations of
x.equals(y) consistently return true
or consistently return false, provided no
information used in equals comparisons on the
objects is modified.
x,
x.equals(null) should return false.
The equals method for class Object implements
the most discriminating possible equivalence relation on objects;
that is, for any non-null reference values x and
y, this method returns true if and only
if x and y refer to the same object
(x == y has the value true).
Note that it is generally necessary to override the hashCode
method whenever this method is overridden, so as to maintain the
general contract for the hashCode method, which states
that equal objects must have equal hash codes.

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 the List
interface. Delegates to the type-specific rem() method
implemented by type-specific abstract Collection
superclass.
remove in interface LongSetCollection.remove(Object)@Deprecated public boolean rem(long k)
remove() instead.
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().
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-specific Set interface.
