Detailed Description

Rule evaluator class. This class provides means for evaluating rules on Atoms. It is a helper class of RuleProcessors. Rules define values depending on atom constellations. They are defined in an INIFile.

BALL::RuleEvaluator::RuleEvaluator ( )

Default constructor

BALL::RuleEvaluator::RuleEvaluator	(	INIFile &	file,
		const String &	prefix
	)

Detailed constructor

BALL::RuleEvaluator::RuleEvaluator ( const RuleEvaluator & evaluator )

Destructor

Member Function Documentation

virtual void BALL::RuleEvaluator::clear ( ) [virtual]

Clear method

void BALL::RuleEvaluator::dump	(	std::ostream &	s = `std::cout`,
		Size	indent_depth = `0`
	)			const

void BALL::RuleEvaluator::extractSection_	(	INIFile &	file,
		const String &	symbol
	)			`[protected]`

const String& BALL::RuleEvaluator::getPrefix ( ) const

Return the prefix of the INI file sections

bool BALL::RuleEvaluator::initialize	(	INIFile &	file,
		const String &	prefix
	)

bool BALL::RuleEvaluator::isValid ( ) const

String BALL::RuleEvaluator::operator() ( const Atom & atom ) const

Rule evaluation. Evaluate all matching rules (in the correct order) and return the corresponding value. If no rule matches, an empty string is returned.

const RuleEvaluator& BALL::RuleEvaluator::operator= ( const RuleEvaluator & evaluator )

Assignment operator

bool BALL::RuleEvaluator::operator== ( const RuleEvaluator & evaluator ) const

Equality operator

void BALL::RuleEvaluator::setPrefix ( const String & prefix )

Set the prefix of the INI file sections
