public class ConstraintVariableConstraint
extends Constraint

Reasoner specific constraint type indicating a Constraint.Type.CONSTRAINT. This shall avoid requiring an attribute for this purpose for all constraints and using it just for temporary reasoning ones.

ConstraintVariableConstraint

public ConstraintVariableConstraint(ConstraintSyntaxTree consSyntax,
                                    IModelElement parent)
                             throws CSTSemanticException

Creates a new constraint from an already parsed syntax tree.

Parameters:

consSyntax - the constraint syntax tree

parent - the object, in which this specific one is embedded

Throws:

CSTSemanticException - in case that the constraint semantics cannot be resolved or that the specified constraint does not evaluate to a boolean expression

Method Detail

getType

public Constraint.IConstraintType getType()

Description copied from class: Constraint

Returns the conceptual type of the constraint. Reasoners may return specialized types here.

Overrides:

getType in class Constraint

Returns:

the conceptual type (Constraint.Type.USUAL)

createConstraint

public Constraint createConstraint(ConstraintSyntaxTree consSyntax)
                            throws CSTSemanticException

Description copied from class: Constraint

Creates a new constraint with same properties but changed constraint syntax tree.

Overrides:

createConstraint in class Constraint

Parameters:

consSyntax - the syntax tree

Returns:

the new constraint

Throws:

CSTSemanticException - in case that the constraint semantics cannot be resolved or that the specified constraint does not evaluate to a boolean expression
