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.
