Detailed Description

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

The Curve class - Defines objects transforming one value into the other.

Template Parameters

ContextType

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

Constructor & Destructor Documentation

Curve()

template<typename ContextType >

grail::evaluator::Curve< ContextType >::Curve ( std::shared_ptr< Evaluator< ContextType >>  childEvaluator )

inlineexplicit

Curve - Constructor.

Parameters

childEvaluator

- Evaluator which output will be transformed by this curve.

Member Function Documentation

DebugDump()

template<typename ContextType >

virtual void grail::evaluator::Curve< ContextType >::DebugDump ( const std::map< const void *, unsigned int > &  nodeMapping, data::EvaluationDebugData &  debugData  ) const

inlinefinaloverrideprotectedvirtual

DebugDump - Called from EvaluateContext, which generates additional debug data for each evaluator. Should be overriden in each derived evaluator to better reflect debug tree topology.

Parameters

nodeMapping	- Maps node pointers to node index.
debugData	- Evaluation debug data which will be filled in this method

Implements grail::evaluator::Evaluator< ContextType >.

Evaluate()

template<typename ContextType >

virtual float grail::evaluator::Curve< ContextType >::Evaluate ( const ContextType &  context, data::UtilityEvaluatorSnapshot *const  snapshot  ) const

inlinefinaloverridevirtual

Evaluate - Called from EvaluateContext which also evaluates context, but without automatically filling snapshot with debug data. Should be overriden for each derived Evaluator.

Parameters

context	- Input data for evaluation
snapshot	- Evaluator snapshot containing debug data describing whole evaluator tree.

Returns

Numerical evaluation of provided context.

Implements grail::evaluator::Evaluator< ContextType >.

Sample()

template<typename ContextType >

virtual float grail::evaluator::Curve< ContextType >::Sample ( float  argument ) const

pure virtual

Sample - Transforms argument into output value depending on the type of Curve.

Parameters

argument

- Value of a curve argument belonging to its domain.

Returns

Transformed argument.
