NAME

       TAU_MAPPING_OBJECT - Declares a mapping object

SYNOPSIS

       C/C++:

       TAU_MAPPING_OBJECT(FunctionInfo FuncIdVar);

DESCRIPTION

       To create storage for an identifier associated with a higher level statement that is
       mapped using TAU_MAPPING, we use the TAU_MAPPING_OBJECT macro. For example, in the
       TAU_MAPPING example, the array expressions are created into objects of a class
       ExpressionKernel, and each statement is an object that is an instance of this class. To
       embed the identity of the statement we store the mapping object in a data field in this
       class. This is shown below:

EXAMPLE

       C/C++ :

       template<class LHS,class Op,class RHS,class EvalTag>
       class ExpressionKernel : public Pooma::Iterate_t {
         public:

           typedef ExpressionKernel<LHS,Op,RHS,EvalTag> This_t;
           //
           // Construct from an Expr.
           // Build the kernel that will evaluate the expression on the
           // given domain.
           // Acquire locks on the data referred to by the expression.
           //
           ExpressionKernel(const LHS&,const Op&,const RHS&,
           Pooma::Scheduler_t&);

           virtual ~ExpressionKernel();

           // Do the loop.
           virtual void run();

         private:

           // The expression we will evaluate.
           LHS lhs_m;
           Op  op_m;
           RHS rhs_m;
           TAU_MAPPING_OBJECT(TauMapFI)
       };
