Constructor Detail

EASyPersistencer

public EASyPersistencer(java.io.File projectFolder)

Sole constructor for this class.

Parameters:

projectFolder - The location of the ProductLineProject.

Method Detail

load

public PLPInfo load()
             throws PersistenceException

Reads the persistent data and transforms them into a ProductLineProject.

Returns:

A ProductLineProject or null.

Throws:

PersistenceException - Will be thrown if the data is invalid or an IOException occur, while reading the persistent data.

refreshModels

public static void refreshModels(PLPInfo plp)

(Re-)Loads all variability models of the specified ProductLineProject from the file system.

Parameters:

plp - A ProductLineProject containing saved models which should be (re-) loaded from the file system

projectPath

public static java.io.File projectPath(PLPInfo plp)

Returns the location of the main ivml file for the given ProductLineProject.

Parameters:

plp - The ProductLineProject holding the ivml file for which this method looks for.

Returns:

The location of the ivml file or null if the location could not be determined.

persistentProject2PLP

private PLPInfo persistentProject2PLP(PersistentProject project)
                               throws PersistenceException

Translates the PersistentProject into a ProductLineProject.

Parameters:

project - The PersistentProject which should be translated.

Returns:

A ProductLineProject representing the given PersistentProject.

Throws:

PersistenceException - Will be thrown if the PersistentProject contains invalid data.

createReasonerConfiguration

private void createReasonerConfiguration(PLPInfo plp,
                                         Model model)

Creates ReasoningConfiguration.

Parameters:

model - A model of type ModelType.INSTANTIATORS holding all instantiator information.

plp - The ProductLineProject where the instantiators should be saved

model2Relatives

private java.util.List<PLPInfo> model2Relatives(Model model)

Creates information related to relative projects..

Parameters:

model - A model of type ModelType.PREDECESSORS or ModelType.SUCCESSORS holding all Prede-/Successor information.

Returns:

The Predecessors/Successor-List

save

public void save(PLPInfo plp)
          throws PersistenceException

Saves the given ProductLineProject persistently.

Parameters:

plp - The ProductLineProject which should be saved.

Throws:

PersistenceException - Will be thrown if an exception occurs while accessing the file system.

getProjectID

public java.lang.String getProjectID()

Returns the ID of a given pl project.

Returns:

the id or null if the specified project has no configuration file.
