Description

Buffer for the communications layer of parallel simulation.

This is an abstract class which has different implementations for specific communication mechanisms. For example, the MPI implementation, cMPICommBuffer encapsulates MPI_Pack() and MPI_Unpack().

Member Function Documentation

◆ isBufferEmpty()

virtual bool isBufferEmpty ( ) const

pure virtual

Returns true if all data in buffer was used up during unpacking. Returns false if there was underflow (too much data unpacked) or still there are unpacked data in the buffer.

◆ assertBufferEmpty()

virtual void assertBufferEmpty ( )

pure virtual

Utility function. To be called after unpacking a communication buffer, it checks whether the buffer is empty. If it is not (i.e. an underflow or overflow occurred), an exception is thrown.
