virtual void ExprEvalInterface::clear

(

)

[pure virtual]

access to the dictionary (namespace,name)->value

if not implemented in a sub-class it returns 0 and does nothing to result clear the dictionary of the evaluator

Implemented in ClhepEvaluator.

virtual double ExprEvalInterface::eval	(	const std::string &	ns,
		const std::string &	expr
	)		[pure virtual]

evaluate an expression expr inside the local namespace

Implemented in ClhepEvaluator.

virtual bool ExprEvalInterface::isDefined	(	const std::string &	ns,
		const std::string &	name
	)		[pure virtual]

check whether a variable is already defined or not

Implemented in ClhepEvaluator.

virtual void ExprEvalInterface::set	(	const std::string &	ns,
		const std::string &	name,
		const std::string &	valueExpr
	)		[pure virtual]

put a new variable named 'namespace:name' into the dictionary of the evaluator

Implemented in ClhepEvaluator.
