Method Details

addConstraint

public void addConstraint(IConstraint constraint)

Description copied from interface: IConstraintVisitor

The data layer implementation should invoke this addConstraint method for each constraint that should be added to the rule engine.

Specified by:

addConstraint in interface IConstraintVisitor

Parameters:

constraint - The constraint that should be added to the rule engine.

addExternalConstraint

public void addExternalConstraint(IExternalRuleDS ruleDS)

Description copied from interface: IConstraintVisitor

The data layer may invoke this method to add an external constraint rule. The rule factory will be used to locate the implementation for the constraint.

Specified by:

addExternalConstraint in interface IConstraintVisitor

Parameters:

ruleDS - Data source providing information about the external constraint rule.

addTable

public void addTable(String targetAttribute,
 IDecisionTableDS tableDS)

Description copied from interface: IConstraintVisitor

This method can be used to add a decision table to a specific attribute as constraint. The decision table should evaluate to a set of values that are valid for the attribute.

Specified by:

addTable in interface IConstraintVisitor

Parameters:

targetAttribute - The attribute for which the decision table applies.

tableDS - Data source containing the definition of the decision table.
