public abstract class AbstractIntSet
extends it.unimi.dsi.fastutil.ints.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()).

Method Detail

iterator

public abstract it.unimi.dsi.fastutil.ints.IntIterator iterator()

Description copied from interface: IntSet

Returns a type-specific iterator on the elements of this set.

Specified by:

iterator in interface it.unimi.dsi.fastutil.ints.IntCollection

Specified by:

iterator in interface it.unimi.dsi.fastutil.ints.IntIterable

Specified by:

iterator in interface IntSet

Specified by:

iterator in interface java.lang.Iterable<java.lang.Integer>

Specified by:

iterator in interface java.util.Collection<java.lang.Integer>

Specified by:

iterator in interface java.util.Set<java.lang.Integer>

Overrides:

iterator in class it.unimi.dsi.fastutil.ints.AbstractIntCollection

Returns:

a type-specific iterator on the elements of this set.

equals

public boolean equals(java.lang.Object o)

Specified by:

equals in interface java.util.Collection<java.lang.Integer>

Specified by:

equals in interface java.util.Set<java.lang.Integer>

Overrides:

equals in class java.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 interface java.util.Collection<java.lang.Integer>

Specified by:

hashCode in interface java.util.Set<java.lang.Integer>

Overrides:

hashCode in class java.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-specific rem() method implemented by type-specific abstract Collection superclass.

Specified by:

remove in interface IntSet

See Also:

Collection.remove(Object)

rem

@Deprecated
public boolean rem(int k)

Deprecated. Please use remove() instead.

Removes an element from this set.

This method is inherited from the type-specific collection this type-specific set is based on, but it should not used as this interface reinstates remove() as removal method. Delegates to the type-specific remove() method specified in the type-specific Set interface.

Specified by:

rem in interface it.unimi.dsi.fastutil.ints.IntCollection

Specified by:

rem in interface IntSet

Overrides:

rem in class it.unimi.dsi.fastutil.ints.AbstractIntCollection
