Detailed Description

template<typename MPTraits>
class ReachabilityUtil< MPTraits >

A utility that will generate the reachable set of a given configuration.

Note

A Reachable Set is a set of states that can reached with respect to its current degrees of freedom

Member Function Documentation

Initialize()

template<typename MPTraits >

void ReachabilityUtil< 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 >

ReachabilityUtil< MPTraits >::ReachableSet ReachabilityUtil< MPTraits >::operator()

(

const CfgType &

_cfg

)

Generate a reachable set of a given configuration

Parameters

_cfg	The extended configuration

Returns

The set of cfgs which are reachable from _cfg.

Print()

template<typename MPTraits >

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

Print internal state of this object.

Parameters

_os	The std::ostream to print to.
