Detailed Description

Loader to do Polymorphic IO.

Author

Ian Scott, Tim Cootes (Manchester) March 2001

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.

Function Documentation

vsl_b_read()

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.

vsl_b_write()

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
