Detailed Description

The main interface for loading a microsim.

It is a black-box where only the options and factories must be supplied on the constructor call. An (empty) instance of the network must be supplied, too, and is filled during loading.

Member Function Documentation

bool NLBuilder::build ( )
virtual

Builds and initialises the simulation.

At first, the network is loaded and the built using "buildNet". If this could be done, additional information is loaded (state dump, weight files, route files, and additional files). If everything could be done, true is returned, otherwise false.

See also:
buildNet
Exceptions:
ProcessErrorIf something fails on network building
Todo:
Again, both returning a bool and throwing an exception; quite inconsistent

void NLBuilder::buildNet ( )
protected

Closes the net building process.

Builds the microsim-structures which belong to a MSNet using the factories filled while loading. Initialises the network using these structures by calling MSNet::closeBuilding. If an error occurs, all built structures are deleted and a ProcessError is thrown.

Exceptions:
ProcessErrorIf the loaded structures could not be built

MSRouteLoaderControl * NLBuilder::buildRouteLoaderControl ( const OptionsCont oc)
protected

Builds the route loader control.

Goes through the list of route files to open defined in the option "route-files" and builds loaders reading these files

Parameters:
[in]ocThe options to read the list of route files to open from
Returns:
The built route loader control
Exceptions:
ProcessErrorIf an error occured

bool NLBuilder::load ( const std::string &  mmlWhat)
protected

Loads a described subpart form the given list of files.

Assuming the given string to be an option name behind which a list of files is stored, this method invokes an XML reader on all the files set for this option.

Parameters:
[in]mmlWhatThe option to get the file list from
Returns:
Whether loading of all files was successfull
