Detailed Description

template<typename MPTraits>
class GroupPath< MPTraits >

A path of connected configurations from a given roadmap.

The implementation uses a vector of VID's as the primary representation. The corresponding configurations are computed lazily upon request.

Constructor & Destructor Documentation

GroupPath()

template<typename MPTraits >

GroupPath< MPTraits >::GroupPath

(

GroupRoadmapType *const

_r = nullptr

)

Construct an empty path.

Parameters

_r	The roadmap used by this path.

Member Function Documentation

Cfgs()

template<typename MPTraits >

const std::vector< typename MPTraits::GroupCfgType > & GroupPath< MPTraits >::Cfgs

Get a copy of the Cfgs in the path.

Warning

If the cfgs in the roadmap are later altered (i.e., if the DOF values or labels are edited), this copy will be out-of-date.

FullCfgs()

template<typename MPTraits >

template<typename MPLibrary >

const std::vector< GroupCfg > GroupPath< MPTraits >::FullCfgs

(

MPLibrary *const

_lib

)

const

Get the current full Cfg path with steps spaced one environment resolution apart. This is not cached due to its size and infrequent usage.

Parameters

_lib	The planning library to use.

Returns

The full path of configurations, including local-plan intermediates between the roadmap nodes.

operator+=() [1/2]

template<typename MPTraits >

GroupPath< MPTraits > & GroupPath< MPTraits >::operator+=

(

const GroupPath< MPTraits > &

_p

)

Append another path to the end of this one.

Parameters

_p	The path to append.

operator+() [1/2]

template<typename MPTraits >

GroupPath< MPTraits > GroupPath< MPTraits >::operator+

(

const GroupPath< MPTraits > &

_p

)

const

Add another path to the end of this one and return the result.

Parameters

_p	The path to add.

operator+=() [2/2]

template<typename MPTraits >

GroupPath< MPTraits > & GroupPath< MPTraits >::operator+=

(

const std::vector< VID > &

_vids

)

Append a new set of VIDs to the end of this path.

Parameters

_vids

The VIDs to append.

operator+() [2/2]

template<typename MPTraits >

GroupPath< MPTraits > GroupPath< MPTraits >::operator+

(

const std::vector< VID > &

_vids

)

const

Add a new set of VIDs to the end of this path and return the result.

Parameters

_vids

The VIDs to add.
