mrpt::graphslam::TUncertaintyPath< GRAPH_T > Struct Template Reference

Detailed Description

template<class GRAPH_T = typename mrpt::graphs::CNetworkOfPoses2DInf>
struct mrpt::graphslam::TUncertaintyPath< GRAPH_T >

Holds the data of an information path.

Path comprises of nodes (TNodeID type) and constraints between them. Only consecutive nodes are connected by edges, thus path.

Assert that the current path is between the given nodeIDs.

Call to this method practically checks if the give nodes match the source and destination nodeIDs.

This method should clearly display all the contents of the structure in textual form, sending it to a CStream.

The default implementation in this base class relies on saveToConfigFile() to generate a plain text representation of all the parameters.

This method load the options from a ".ini"-like file or memory-stored string list.

Only those parameters found in the given "section" and having the same name that the variable are loaded. Those not found in the file will stay with their previous values (usually the default values loaded at initialization). An example of an ".ini" file:

[section]
resolution = 0.10 // blah blah...
modeSelection = 1 // 0=blah, 1=blah,...
