Constructor Detail

AbleCorrelationEngine

public AbleCorrelationEngine(AbleRuleSet theRuleSet,
                             AbleLogger theTracer,
                             AbleRuleBlock theRuleBlock)

Constructor for AbleCorrelationEngine.

Parameters:

theRuleSet -

theTracer -

theRuleBlock -

Method Detail

isRuleBlockValid

public boolean isRuleBlockValid(AbleRuleBlock theRuleBlock)

Make sure the current ruleblock is "executable" by this inference engine. Only assertion rules and pattern match rules are processed.

The ruleblock is invalid if any of the following are present in the ruleblock:

Conditional rule

If-then-else rule

Predicate rule

Iteration rule

All reasons for validation failures are appended to the AbleRuleSet's myIsExReason variable. If validation fails, the inference engine must call myRuleSet.addIsExReason(java.lang.String) to append the reason.

Specified by:

isRuleBlockValid in class AbleInferenceEngine

Returns:

true, if the ruleset is OK; false, if the ruleset is not executable.

infer

public void infer(AbleRuleBlock theRuleBlock)
           throws AbleDataException

Description copied from class: AbleInferenceEngine

Inference over the set of rules in the specified ruleblock object.

Specified by:

infer in class AbleInferenceEngine

Parameters:

theRuleBlock - The ruleblock to be processed by the engine.

Throws:

AbleDataException

See Also:

AbleInferenceEngine.infer(AbleRuleBlock)

setControlParameter

public void setControlParameter(java.lang.String theControlParameter,
                                java.lang.Object theValue)
                         throws AbleDataException

Set the specified control parameter on the associated inference engine.

Specified by:

setControlParameter in class AbleInferenceEngine

Throws:

AbleDataException

getControlParameter

public java.lang.Object getControlParameter(java.lang.String theControlParameter)
                                     throws AbleDataException

Returns the specified control parameter on the associated inference engine.

Specified by:

getControlParameter in class AbleInferenceEngine

Throws:

AbleDataException

evaluateActions

public void evaluateActions(AbleCorrelationRule theRule)
                     throws AbleDataException

Evaluate the actions in a Correlation rule

Throws:

AbleDataException
