AbstractSet Class Reference
#include <coherence/util/AbstractSet.hpp>
Inherits AbstractCollection, and Set.
Inherited by DeltaSet, LiteSet, NullImplementation::NullSet, and SubSet.
List of all members.
Detailed Description
This class provides a skeletal implementation of the Set
interface to minimize the effort required to implement this interface.
The process of implementing a set by extending this class is identical to that of implementing a Collection by extending AbstractCollection, except that all of the methods and constructors in subclasses of this class must obey the additional constraints imposed by the Set
interface (for instance, the add
method must not permit addition of multiple instances of an object to a set).

virtual bool | equals (Object::View v) const |

virtual size32_t | hashCode () const |
| Return a hash code value for the Object.
This method is supported for the benefit of hash-based containers.
The general contract of hashCode is:
-
Whenever it is invoked on the same Object more than once during an execution of an application, the
hashCode method must consistently return the same value, provided no information used in equals comparisons on the object is modified. This value need not remain consistent from one execution of an application to another execution of the same application.
-
If two Objects are equal according to the
equals method, then calling the hashCode method on each of the two Objects must produce the same value.
-
It is not required that if two Objects are unequal according to the
equals method, then calling the hashCode method on each of the two objects must produce distinct results. However, the programmer should be aware that producing distinct results for unequal objects may improve the performance of hash-based containers.
The default implementation is identity based.
- Returns:
- a hash code value for this Object
