Function Documentation

load_eva()

template<Evaluator E>

bool load_eva	(	std::istream &	in,
		E *	e )

Loads the persistent state of an evaluator, if supported.

Template Parameters

E	an Evaluator type

Parameters

[in,out]	in	input stream
[in,out]	e	pointer to the evaluator instance

Returns

true if the evaluator was loaded successfully or if the evaluator doesn't support persistence

This function provides optional persistence support for evaluators. If the evaluator type E defines a member function with the signature:

bool load(std::istream &);

then that function is invoked. Otherwise, the evaluator is assumed to have no persistent state and the operation succeeds trivially.

save_eva()

template<Evaluator E>

bool save_eva	(	std::ostream &	out,
		const E &	e )

Saves the persistent state of an evaluator, if supported.

Template Parameters

E	an Evaluator type

Parameters

[out]	out	output stream
[in]	e	evaluator instance

Returns

true if the evaluator was saved successfully or if the evaluator doesn't support persistence

This function provides optional persistence support for evaluators. If the evaluator type E defines a member function with the signature:

bool save(std::ostream &) const;

then that function is invoked. Otherwise, the evaluator is assumed to have no persistent state and the operation succeeds trivially.
