smash::ExperimentBase Class Reference

#include <experiment.h>

Non-template interface to Experiment<Modus>.

This class allows to call into the public interface of Experiment<Modus> without the need to know the specific Modus. The interface is meant for main() to set up the experiment and then run takes over.

virtualdefault

The virtual destructor avoids undefined behavior when destroying derived objects.

Member Function Documentation

create()

ExperimentPtr smash::ExperimentBase::create ( Configuration &  config, const std::filesystem::path &  output_path  )

static

Factory method that creates and initializes a new Experiment<Modus>.

This function creates a new Experiment object. The Modus template argument is determined by the config argument.

Parameters

[in,out]	config	The configuration object that sets all initial conditions of the experiment.
[in]	output_path	The directory where the output files are written.

Returns

An owning pointer to the Experiment object, using the ExperimentBase interface.

Exceptions

InvalidModusRequest

This exception is thrown if the Modus string in the config object does not contain a valid string.

Most of the Configuration values are read starting from this function. The configuration itself is documented in General

run()

virtual void smash::ExperimentBase::run ( )

pure virtual

Runs the experiment.

The constructor does the setup of the experiment. The run function executes the complete experiment.

Implemented in smash::Experiment< Modus >.
