Detailed Description

template<typename MPTraits>
class PathModifierMethod< MPTraits >

Base algorithm abstraction for Path Modifiers.

PathModifierMethod has one main method, Modify, which takes an input path and produces a valid output path.

Member Function Documentation

Modify()

template<typename MPTraits >

void PathModifierMethod< MPTraits >::Modify ( vector< CfgType > &  _path, vector< CfgType > &  _newPath  )

virtual

Modifies the input path to a new valid path

Parameters

_path	A path of configurations within a resolution distance of each other
_newPath	An empty vector to place the resulting modified path

Usage:\n

PathModifierPointer pm = this->GetPathModifier(m_pmLabel);
vector<CfgType> inputPath, outputPath;
pm->Modify(inputPath, outputPath);

ModifyImpl()

template<typename MPTraits >

virtual bool PathModifierMethod< MPTraits >::ModifyImpl ( RoadmapType *  _graph, vector< CfgType > &  _path, vector< CfgType > &  _newPath  )

protectedpure virtual

Modifies the input path to a new valid path

Parameters

_path	A path of configurations within a resolution distance of each other
_newPath	An empty vector to place the resulting modified path

Returns

Success/failed modification

AddToPath()

template<typename MPTraits >

void PathModifierMethod< MPTraits >::AddToPath ( vector< CfgType > &  _path, LPOutput< MPTraits > *  _lpOutput, CfgType &  _end  )

protected

Appends local plan to path

Parameters

_path	Path to append local plan to
_lpOutput	Local plan output
_end	End Cfg of local plan

GetPathVIDs()

template<typename MPTraits >

vector< typename MPTraits::RoadmapType::VID > PathModifierMethod< MPTraits >::GetPathVIDs ( vector< CfgType > &  _path, RoadmapType *  _graph  )

protected

Extract path VIDs in roadmap from path

Parameters

_path	Path to extract VIDs from
_graph	RoadmapGraph containing path nodes

Returns

Path VIDs

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.

Initialize()

template<typename MPTraits >

virtual void MPBaseObject< MPTraits >::Initialize ( )

virtualinherited

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.

SetName()

template<typename MPTraits >

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
