A.4.14 C++ Bindings on all MPI Classes

The C++ language requires all classes to have four special functions: a default constructor, a copy constructor, a destructor, and an assignment operator. The bindings for these functions are listed below; their semantics are discussed in Section 16.1.5. The two constructors are not virtual. The bindings prototype functions are using the type hCLASSi rather than listing each function for every MPI class. The token hCLASSi can be replaced with valid MPI- 2 class names, such as Group, Datatype, etc., except when noted. In addition, bindings are provided for comparison and inter-language operability from Sections 16.1.5 and 16.1.9.

A.4.15 Construction / Destruction

namespace MPI {

hCLASSi::hCLASSi() hCLASSi:: hCLASSi()

};

A.4.16 Copy / Assignment

namespace MPI {

hCLASSi::hCLASSi(const hCLASSi& data)

hCLASSi& hCLASSi::operator=(const hCLASSi& data)

};

A.4.17 Comparison

Since Status instances are not handles to underlying MPI objects, the operator==() and operator!=() functions are not de ned on the Status class.

namespace MPI {

bool hCLASSi::operator==(const hCLASSi& data) const

bool hCLASSi::operator!=(const hCLASSi& data) const

};

A.4.18 Inter-language Operability

Since there are no C++ MPI::STATUS_IGNORE and MPI::STATUSES_IGNORE objects, the result of promoting the C or Fortran handles (MPI_STATUS_IGNORE and

MPI_STATUSES_IGNORE) to C++ is unde ned.
