ConstraintsConverter

public ConstraintsConverter()

Make a new empty converter.

Method Details

newBundle

public static ConstraintsConverter newBundle()

Make a new ConstraintsConverter and fulfill it using a default converter for each supported constraint.

Returns:

a fulfilled converter.

register

public void register(ConstraintConverter<? extends Constraint> c)

Register a converter for a specific constraint.

Parameters:

c - the converter to register

getSupportedJavaConstraints

public Set<Class<? extends Constraint>> getSupportedJavaConstraints()

Get the Java constraints that are supported by the converter.

Returns:

a set of classes derived from Constraint that may be empty

getSupportedJSONConstraints

public Set<String> getSupportedJSONConstraints()

Get the JSON constraints that are supported by the converter.

Returns:

a set of constraints identifier that may be empty

fromJSON

public Constraint fromJSON(Model mo, net.minidev.json.JSONObject in) throws JSONConverterException

Convert a json-encoded constraint.

Parameters:

mo - the model to rely on

in - the constraint to decode

Returns:

the resulting constraint

Throws:

JSONConverterException - if the conversion failed

toJSON

public net.minidev.json.JSONObject toJSON(Constraint o) throws JSONConverterException

Serialise a constraint.

Parameters:

o - the constraint

Returns:

the resulting encoded constraint

Throws:

JSONConverterException - if the conversion failed

listFromJSON

public List<SatConstraint> listFromJSON(Model mo, net.minidev.json.JSONArray in) throws JSONConverterException

Convert a list of json-encoded sat-constraints.

Parameters:

mo - the model to rely on

in - the constraints to decode

Returns:

the constraint list. Might be empty

Throws:

JSONConverterException - if the conversion failed

toJSON

public net.minidev.json.JSONArray toJSON(Collection<SatConstraint> e) throws JSONConverterException

Serialise a list of sat-constraints.

Parameters:

e - the list to serialise

Returns:

the resulting encoded list

Throws:

JSONConverterException - if the conversion failed
