Detailed Description

Loader to do Polymorphic IO.

Author:

You should include this file if you want to do polymorphic IO (i.e. save a class by its base-class pointer.)

Definition in file vsl_binary_loader.h.

#include <vsl/vsl_binary_io.h>

Function Documentation

template<class BaseClass>

void vsl_b_read	(	vsl_b_istream &	bfs,
		BaseClass *&	b
	)			[inline]

Loads object and sets base class pointer.

Determines which derived class object on bfs belongs to, loads it and sets b to be a pointer to it. (Class must be one given to Loader by the append method). If bfs indicates a NULL pointer, b will be set to NULL. If b not initially NULL, *b will be deleted.

Definition at line 95 of file vsl_binary_loader.h.

template<class BaseClass>

void vsl_b_write	(	vsl_b_ostream &	bfs,
		const BaseClass *	b
	)

Binary file stream output operator for pointer to class.

This works correctly even if b is a NULL pointer
