MapListenerSupport::WrapperSynchronousListener Class Reference

#include <coherence/util/MapListenerSupport.hpp>

Inherits Object, and MapListenerSupport::SynchronousListener.

List of all members.

Detailed Description

A wrapper class that turns the specified MapListener into a synchronous listener.

Public Types

typedef spec::Handle Handle
 WrapperSynchronousListener Handle definition.
typedef spec::View View
 WrapperSynchronousListener View definition.
typedef spec::Holder Holder
 WrapperSynchronousListener Holder definition.

Public Member Functions

virtual void entryInserted (MapEvent::View vEvent)
 Invoked when a map entry has been inserted.

 vEvent the MapEvent carrying the insert information
virtual void entryUpdated (MapEvent::View vEvent)
 Invoked when a map entry has been updated.

 vEvent the MapEvent carrying the update information
virtual void entryDeleted (MapEvent::View vEvent)
 Invoked when a map entry has been removed.

 vEvent the MapEvent carrying the delete information
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.
