Detailed Description

An AbstractSet is an abstract implementation of the Set interface. This implementation does not support adding. A subclass must implement the abstract methods iterator() and size().

Constructor & Destructor Documentation

AbstractSet()

java.util.AbstractSet< E >.AbstractSet ( )

inlineprotected

Constructs a new instance of this AbstractSet.

Member Function Documentation

equals()

boolean java.util.AbstractSet< E >.equals ( Object  object )

inline

Compares the specified object to this Set and returns true if they are equal. The object must be an instance of Set and contain the same objects.

Parameters

object

the object to compare with this set.

Returns

true 

if the specified object is equal to this set,

false 

otherwise

See also

hashCode

Implements java.util.Set< E >.

hashCode()

int java.util.AbstractSet< E >.hashCode ( )

inline

Returns the hash code for this set. Two set which are equal must return the same value. This implementation calculates the hash code by adding each element's hash code.

Returns

the hash code of this set.

See also

equals

Implements java.util.Set< E >.

removeAll()

boolean java.util.AbstractSet< E >.removeAll ( Collection<?>  collection )

inline

Removes all occurrences in this collection which are contained in the specified collection.

Parameters

collection

the collection of objects to remove.

Returns

true 

if this collection was modified,

false 

otherwise.

Exceptions

UnsupportedOperationException

if removing from this collection is not supported.

Implements java.util.Set< E >.
