ReadOnlyMultiList::SetView Class Reference

#include <coherence/util/ReadOnlyMultiList.hpp>

Inherits WrapperCollections::AbstractWrapperSet.

List of all members.

Detailed Description

SetView exposes the underlying ReadOnlyMultiList through the Set interface, maintaining correct equals() and hashCode() semantics.

Public Types

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

Protected Member Functions

  SetView (ReadOnlyMultiList::Holder ohSet)
  Construct a SetView over the specified ReadOnlyMultiList.
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.
