applyRules

public java.util.Set applyRules(java.lang.String rulesetURI,
                                java.util.Set inputObjects,
                                java.util.Set outputObjectsTypeFilter,
                                java.util.Set outputObjectsCreatorFilter)

                                RulesServiceException

Applies a named set of rules to the set of objects provided by the caller in order to produce a resultant set of objects.

Parameters:

rulesetURI - The uri of the rule set which contains the set of rules that is to be applied.

inputObjects - The set of objects to which the rules are to be applied

outputObjectsTypeFilter - A set of class objects used to perform type-based selection of the return objects.

outputObjectsCreatorFilter - A set of output object creator name strings to be used to perform creator-name selection of the return objects after type-based filtering has been performed.

Returns:

A filtered set of objects which resulted from the application of the rules.

Throws:

java.lang.IllegalArgumentException - Thrown if rulesetURI is null or zero-length, or if inputObjects is null or if outputObjectsTypeFilter is null

RulesServiceException - thrown on an error in the rules service
