public abstract class AbstractIntSet extends AbstractIntCollection implements java.lang.Cloneable, IntSet
An abstract class providing basic methods for sets implementing a
type-specific interface.
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()
).

iterator
Description copied from interface:IntCollection
Returns a type-specific iterator on the elements of this collection.- Specified by:

- Specified by:

in interfacejava.util.Set<java.lang.Integer>
- Specified by:

in classAbstractIntCollection
- Returns:
- a type-specific iterator on the elements of this collection.
- See Also:
Iterable.iterator()

equals
public boolean equals(java.lang.Object o)- Specified by:
equals
in interfacejava.util.Collection<java.lang.Integer>
- Specified by:
equals
in interfacejava.util.Set<java.lang.Integer>
- Overrides:
equals
in classjava.lang.Object
-
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.- Specified by:
hashCode
in interfacejava.util.Collection<java.lang.Integer>
- Specified by:
hashCode
in interfacejava.util.Set<java.lang.Integer>
- Overrides:
hashCode
in classjava.lang.Object
- Returns:
- a hash code for this set.
-
remove
public boolean remove(int k)Removes an element from this set. Delegates to the type-specificrem()
method implemented by type-specific abstractCollection
superclass. -
rem
@Deprecated public boolean rem(int 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()
. Delegates to the type-specificremove()
method specified in the type-specificSet
interface.- Specified by:
rem
in interfaceIntCollection
- Specified by:
rem
in interfaceIntSet
- Overrides:
rem
in classAbstractIntCollection
