Detailed Description

template<typename MPTraits>
class TimeEvaluator< MPTraits >

A stop-watch like evaluator that returns false after a set amount of time.

This class maintains a separate clock for each instance. For a global clock use ConditionalEvaluator with the TimeMetric.

Member Function Documentation

Initialize()

template<typename MPTraits >

void TimeEvaluator< MPTraits >::Initialize

overridevirtual

Initialize this object for the current MPProblem. This should reset any internal state of the algorithms so that they are ready for execution. It is also the place to initialize any state that depends on the current problem.

Warning

This member will be called for every compiled algorithm in the planning library - even those that will not be used. If an algorithm needs to do expenisve setup, then this method should only set a flag that tells it to do so on first use. The only exceptions are the MPStrategies, which will only have their initialize called on first use.

Reimplemented from MPBaseObject< MPTraits >.

operator()()

template<typename MPTraits >

bool TimeEvaluator< MPTraits >::operator() ( )

overridevirtual

Evaluate a roadmap.

Returns

True if this roadmap meets the evaluation criteria.

Implements MapEvaluatorMethod< MPTraits >.

SetEdgeIntervals()

template<typename MPTraits >

virtual void MapEvaluatorMethod< MPTraits >::SetEdgeIntervals ( EdgeIntervals  _edgeIntervals )

virtualinherited

Set the edge intervals of a roadmap.

Reimplemented in SIPPMethod< MPTraits >.

SetMinEndtime()

template<typename MPTraits >

virtual void MapEvaluatorMethod< MPTraits >::SetMinEndtime ( double  _minEndtime )

virtualinherited

Set the minimum end time of a path.

Reimplemented in SIPPMethod< MPTraits >.

Print()

template<typename MPTraits >

void MPBaseObject< MPTraits >::Print ( std::ostream &  _os ) const

virtualinherited

Print internal state of this object.

Parameters

_os	The std::ostream to print to.

void MPBaseObject< MPTraits >::SetName ( const std::string &  _s )

protectedinherited

Parameters

_s	Class name

GetBaseFilename()

template<typename MPTraits >

const std::string & MPBaseObject< MPTraits >::GetBaseFilename ( ) const

protectedinherited

Returns

base file name from MPProblem

Member Data Documentation

m_activeRobots

template<typename MPTraits >

std::vector<size_t> MapEvaluatorMethod< MPTraits >::m_activeRobots

protectedinherited

The active robots, used only by group map evaluators. Depending on the evaluator, the usage could be different, but the current use case is to set the robot(s) that are being moved, then a clearance check is done only considering those specified bodies (see MinimumClearanceEvaluator).

Todo:

This is an artifact of developing robot groups. It should be replaced by using a proper subgroup where each robot within is active.
