NAME

ACE_Equal_To - Function object for comparing two objects of the given type for equality.

SYNOPSIS

#include <ace/Functor_T.h>

template<class TYPE> class ACE_Equal_To { public: int operator () (const TYPE &lhs, const TYPE &rhs) 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

int operator () (const TYPE &lhs, const TYPE &rhs) const;
