public class DefaultConstraint
extends Constraint

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

Constructor Detail

DefaultConstraint

public DefaultConstraint(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

setDefaultConstraints

public void setDefaultConstraints(ConstraintList defaultConstraints)

Sets the default constraint list explicitly. Default constraints can be evaluated directly without further constraint/variable dependencies. The attached constraints are temporary.

Parameters:

defaultConstraints - the default constraints, may be null for none

setDeferredDefaultConstraints

public void setDeferredDefaultConstraints(ConstraintList deferredDefaultConstraints)

Sets the deferred default constraint list explicitly. Default constraints have dependencies and shall be evaluated (initially) after the default constraints. The attached constraints are temporary.

Parameters:

deferredDefaultConstraints - the deferred default constraints, may be null for none

getDefaultConstraints

public ConstraintList getDefaultConstraints()

Returns the default constraint list explicitly. Default constraints can be evaluated directly without further constraint/variable dependencies. The attached constraints are temporary.

Returns:

the default constraints, may be null for none

getDeferredDefaultConstraints

public ConstraintList getDeferredDefaultConstraints()

Returns the deferred default constraint list explicitly. Default constraints have dependencies and shall be evaluated (initially) after the default constraints. The attached constraints are temporary.

Returns:

the deferred default constraints, may be null for none

getAttachedConstraintsSize

public int getAttachedConstraintsSize()

Returns the number of attached constraints. The attached constraints are temporary.

Returns:

the number of attached constraints

getType

public Constraint.IConstraintType getType()

Returns the conceptual type of the constraint.

Overrides:

getType in class Constraint

Returns:

the conceptual type (Constraint.Type.DEFAULT)

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
