Class HeuristicPojoProcessor

java.lang.Object
  org.apache.tuscany.sca.implementation.java.introspect.impl.BaseJavaClassVisitor
      org.apache.tuscany.sca.implementation.java.introspect.impl.HeuristicPojoProcessor

All Implemented Interfaces:

JavaClassVisitor

public class HeuristicPojoProcessor
extends BaseJavaClassVisitor

Heuristically evaluates an un-annotated Java implementation type to determine services, references, and properties according to the algorithm described in the SCA Java Client and Implementation Model Specification

TODO Implement:

When no service interface is annotated, need to calculate a single service comprising all public methods that are not reference or property injection sites. If that service can be exactly mapped to an interface implemented by the class then the service interface will be defined in terms of that interface.
