Method Detail

compile

public Flow compile(RuleSet source,
                    FactoryConfig factoryConfig)
             throws ConfigurationException

Compiles rule set to flow.

Parameters:

ruleSet - Rule set. The rule set gets modified during compilation and shall be discarded after compilation.

classLoader - Classloader to load rule classes for introspection. If null, then this class' classloader is used.

Returns:

Flow definition.

Throws:

ConfigurationException

createInferenceMethodNode

protected Node createInferenceMethodNode(RuleSet ruleSet,
                                         Rule rule,
                                         Method method,
                                         Flow owner)

Creates inference method node. Subclasses can override this method to provide custom node implementations and additional configuration.

Parameters:

method -

rule -

ruleSet -

ret -

Returns:

getInferAnnotation

protected Infer getInferAnnotation(Method method)

Extracts inference information from the method. This implementation takes it from Infer annotation. Subclasses can do it in a different way.

Parameters:

method -

Returns:

createNode

protected Node createNode(Flow flow,
                          Class<?> type)

main

public static void main(String[] args)
                 throws Exception

Parameters:

args -

Throws:

Exception

printDiagnostic

protected static void printDiagnostic(org.eclipse.emf.common.util.Diagnostic diagnostic,
                                      String indent)
