Method Detail

iterator

public abstract IntIterator iterator()

Description copied from interface: IntCollection

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 extends Collection.

Specified by:

iterator in interface IntCollection

Specified by:

iterator in interface 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>

Specified by:

iterator in class AbstractIntCollection

Returns:

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

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)

Description copied from interface: IntSet

Removes an element from this set.

Note that the corresponding method of the type-specific collection is rem(). This unfortunate situation is caused by the clash with the similarly named index-based method in the List interface.

Specified by:

remove in interface IntSet

Collection.remove(Object)

remove

public boolean remove(java.lang.Object o)

Delegates to the corresponding type-specific method.

Specified by:

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

Specified by:

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

Overrides:

remove in class AbstractIntCollection
