Member Function Documentation

DebugDump()

template<typename ContextType >

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

protectedpure virtual

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

Implemented in grail::evaluator::Curve< ContextType >, grail::evaluator::Aggregator< ContextType >, and grail::evaluator::Consideration< ContextType >.

Evaluate()

template<typename ContextType >

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

protectedpure virtual

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.

Implemented in grail::evaluator::Consideration< ContextType >, grail::evaluator::Curve< ContextType >, grail::evaluator::MaxAggregator< ContextType >, grail::evaluator::MinAggregator< ContextType >, grail::evaluator::AverageAggregator< ContextType >, grail::evaluator::ProductAggregator< ContextType >, and grail::evaluator::SumAggregator< ContextType >.

EvaluateContext()

template<typename ContextType >

float grail::evaluator::Evaluator< ContextType >::EvaluateContext ( const ContextType &  context, data::UtilityEvaluatorSnapshot *const  snapshot  ) const

inline

EvaluateContext - evaluates provided context and if provided snapshot is not empty, fills it with debug data describing this node.

Parameters

context	- input data for evaluation
snapshot	- evaluator snapshot containing debug data describing whole evaluator tree

Returns

evaluation score
