Class SolverDispatcher

java.lang.Object

solvers.dispatchers.SolverDispatcher

public class SolverDispatcher
extends Object

Server side of the solver interface.
This object takes a model, instantiates the correct solver, and solves it.
Should probably be rewritten using a different data structure to hold model information

Method Details

solve

public void solve(File file)
           throws InputDataException,
SolverException

Solves the model in file.

Parameters:

file - the file

Throws:

InputDataException - if some input data are malformed

SolverException - if something goes wrong during solution

stop

public void stop()

Stops What-if analysis and invalidates results

hasStopped

public boolean hasStopped()

solve

public void solve(ExactModel model)
           throws InputDataException,
SolverException

Solves input model. This method will look for what-if analysis data and perform a what-if analysis if requested.
Author: Bertoli Marco

Parameters:

model - model to be solved

Throws:

InputDataException - if some input data are malformed

SolverException - if something goes wrong during solution

finalDispatch

public void finalDispatch(ExactModel model,
 int iteration)
                   throws InputDataException,
SolverException

Throws:

InputDataException

SolverException

addSolverListener

public void addSolverListener(SolverDispatcher.SolverListener listener)

Adds a solver listener to be notified when computation of an iteration terminates. This is useful for notification of a progress window. Only one listener is allowed.

Parameters:

listener - listener to be added or null to remove previous one.

getModel

public ExactModel getModel()
