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-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 IntIterator 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.

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:
