Class IndexBasedModelConverter

java.lang.Object

de.rwth.swc.coffee4j.model.converter.IndexBasedModelConverter

All Implemented Interfaces:

ModelConverter

public class IndexBasedModelConverter
extends Object
implements ModelConverter

A ModelConverter based on using the indices of supplied Parameter and Value. This means that the first parameter in the list of InputParameterModel.getParameters() is translated to 0, the second one to 1 and so on and so fourth. The same is done with values per parameter. These integers are then used for TupleList and Combination, so [0, 1] is a combination where the first parameter is mapped to it's first value and the second one to its second value.

Constructor Detail

IndexBasedModelConverter

public IndexBasedModelConverter(InputParameterModel model)

Creates and initializes a new converter with a SimpleCartesianProductConstraintConverter to convert Constraint to TupleList.

Parameters:

model - the model which is converted. Must not be null

IndexBasedModelConverter

public IndexBasedModelConverter(InputParameterModel model,
                                IndexBasedConstraintConverter constraintsConverter)

Creates and initializes a new converter with the given model and constraints converter.

Parameters:

model - the model which is converted. Must not be null

constraintsConverter - the converter used to convert the model's Constraint to TupleList

Method Detail

getModel

public InputParameterModel getModel()

Specified by:

getModel in interface ModelConverter

Returns:

the original model which is converted by this ModelConverter

getConvertedModel

public CombinatorialTestModel getConvertedModel()

Specified by:

getConvertedModel in interface ModelConverter

Returns:

the conversion of the original model (ModelConverter.getModel())

convertCombination

public int[] convertCombination(Combination combination)

Description copied from interface: ModelConverter

Converts a Combination object to an integer array representation with the corresponding value number. If the array returned by this method is given into ModelConverter.convertCombination(int[]), a Combination equal to the original one should be returned.

Specified by:

convertCombination in interface ModelConverter

Parameters:

combination - the combination to be converted. Must not be null

Returns:

the corresponding integer array to that it matches the model conversion

convertCombination

public Combination convertCombination(int[] combination)

Description copied from interface: ModelConverter

Converts a combinations represented by an integer array into a Combination object with the corresponding parameters and values.

Specified by:

convertCombination in interface ModelConverter

Parameters:

combination - the combination to be converted. Must not be null

Returns:

the corresponding Combination so that it matches the model conversion

convertParameter

public int convertParameter(Parameter parameter)

Description copied from interface: ModelConverter

Converts a Parameter object into an equivalent integer representation. If the integer returned by this method is given to ModelConverter.convertParameter(int), the original parameter is returned.

Specified by:

convertParameter in interface ModelConverter

Parameters:

parameter - the parameter to convert. Needs to be in the original model, otherwise success of this method is not guaranteed. Must not be null

Returns:

the corresponding integer representation so that it matches the model conversion

convertParameter

public Parameter convertParameter(int parameter)

Description copied from interface: ModelConverter

Converts an integer representation back to a Parameter object.

Specified by:

convertParameter in interface ModelConverter

Parameters:

parameter - the parameter to convert. Needs to be in the original model, otherwise success of this method is not guaranteed. Must not be negative

Returns:

the corresponding Parameter representation so that it matches the model conversion

convertValue

public int convertValue(Parameter parameter,
                        Value value)

Description copied from interface: ModelConverter

Converts a Value to an integer representation. As values are only unique in their corresponding Parameters, the parameter is needed as well. It can be converted using ModelConverter.convertParameter(Parameter). If the converted value and parameter are given to ModelConverter.convertValue(int, int), the original value is returned.

Specified by:

convertValue in interface ModelConverter

Parameters:

parameter - the parameter in which the value is located

value - the value to convert

Returns:

the corresponding integer representation so that it matches the model conversion

convertValue

public Value convertValue(int parameter,
                          int value)

Description copied from interface: ModelConverter

Converts the integer representation of a value into a Value object. The parameter is needed since values are only unique in the context of their parameters. The parameter can be converted with ModelConverter.convertParameter(int).

Specified by:

convertValue in interface ModelConverter

Parameters:

parameter - the parameter in which the value is located

value - the value to convert

Returns:

the corresponding Value representation so that it matches the model conversion

convertConstraint

public TupleList convertConstraint(Constraint constraint)

Description copied from interface: ModelConverter

Converts a Constraint object into a TupleList representation which is equal. If the TupleList returned by this method is given to ModelConverter.convertConstraint(TupleList), the original constraint will be returned.

Specified by:

convertConstraint in interface ModelConverter

Parameters:

constraint - the constraint to convert. Needs to be one in the original model, otherwise success of this method is not guaranteed. Must not be null

Returns:

the corresponding TupleList representation so that it matches the model conversion

convertConstraint

public Constraint convertConstraint(TupleList constraint)

Description copied from interface: ModelConverter

Converts a TupleList object into a Constraint representation which is equal.

Specified by:

convertConstraint in interface ModelConverter

Parameters:

constraint - the constraint to convert. Needs to be one in the original model, otherwise success of this method is not guaranteed. Must not be null

Returns:

the corresponding Constraint representation so that it matches the model conversion
