Detailed Description

template<typename ContextType>
class grail::evaluator::PowerFunction< ContextType >

The PowerFunction class - Power function.

Template Parameters

ContextType - Type of evaluated object. By default - ValueTuple(AIEntity, Blackboard).

Constructor & Destructor Documentation

◆ PowerFunction() [1/2]

template<typename ContextType >

grail::evaluator::PowerFunction< ContextType >::PowerFunction	(	std::shared_ptr< Evaluator< ContextType >>	childEvaluator,
		float	slope,
		float	intercept,
		float	exponent
	)

inline

PowerFunction - Constructor.

Parameters

childEvaluator	- Evaluator which output will be transformed by this curve.
slope	- "a" parameter of linear function which will be raised to power.
intercept	- "b" parameter of linear function which will be raised to power.
exponent	- Value to which power linear function will be raised.

◆ PowerFunction() [2/2]

template<typename ContextType >

grail::evaluator::PowerFunction< ContextType >::PowerFunction	(	std::shared_ptr< Evaluator< ContextType >>	childEvaluator,
		std::pair< float, float >	firstPoint,
		std::pair< float, float >	secondPoint,
		float	exponent
	)

inline

PowerFunction - Constructor.

Parameters

childEvaluator	- Evaluator which output will be transformed by this curve.
firstPoint	- Beginning of the segment describing linear function, which will be raised to power.
secondPoint	- End of the segment describing linear function, which will be raised to power.
exponent	- Value to which power linear function will be raised.
