## NAME

ACE_Hash -

Function object for hashing

## SYNOPSIS

    #include <ace/Functor_T.h>

    template<class TYPE>
    class ACE_Hash
    {
      public:
        u_long operator () (const TYPE &t) const;
    };

## DESCRIPTION

Templatized classes for implementing function objects that are used in various places in ACE. There are currently two major categories of function objects in ACE: GOF Command Pattern objects, and STL-style functors for comparison of container elements. The command objects are invoked via an execute () method, while the STL-style functors are invoked via an operator() () method.

## PUBLIC MEMBERS

    u_long operator () (const TYPE &t) const;

Simply calls t.hash ()
