Method Detail

evaluateRuleSet

Iterator evaluateRuleSet(String ruleSetUri,
                         Object[] inputObjects)
                         throws RemoteException,
                                IllegalArgumentException,
                                ApplicationException

Applies a named set of rules to the set of objects provided by the caller and returns an iterator over the resultant set of objects.

Parameters

ruleSetUri - The URI of the rule set which contains the set of rules.

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

Returns

The set of objects which resulted from the application of the rules.

Throws

IllegalArgumentException - if ruleSetUri is null or zero-length, or if inputObjects is null.

ApplicationException - if the rule set execution subsystem is unable to execute the rule set.

RemoteException - if a communication error occurs during the execution of a remote method call.

evaluateRuleSet

Iterator evaluateRuleSet(String ruleSetUri,
                         Object[] inputObjects,
                         ObjectFilter filter)
                         throws RemoteException,

                                ApplicationException

Applies a named set of rules to the set of objects provided by the caller and returns an iterator over the resultant set of objects that pass the given filter.

Parameters

ruleSetUri - The URI of the rule set which contains the set of rules.

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

filter - An ObjectFilter used to filter the results of rule exection.

Returns

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

Throws

IllegalArgumentException - if ruleSetUri is null or zero-length, or if inputObjects is null.

ApplicationException - if the rule set execution subsystem is unable to execute the rule set.

RemoteException - if a communication error occurs during the execution of a remote method call.

evaluateRule

Iterator evaluateRule(String ruleSetUri,
                      String ruleName,

Applies a named rule to the set of objects provided by the caller and returns an iterator over the resultant set of objects.

Parameters

ruleSetUri - The URI of the rule set which contains the rule to be executed.

ruleName - The name of the rule to be executed.

inputObjects - The set of objects to which the rule is to be applied

Returns

The set of objects which resulted from the application of the rule.

Throws

IllegalArgumentException - if ruleSetUri or ruleName are null or zero-length, or if inputObjects is null.

ApplicationException - if the rule set execution subsystem is unable to execute the rule.

RemoteException - if a communication error occurs during the execution of a remote method call.
