package org.apache.tuscany.sca.implementation.spring.introspect;
Provides introspection functions for Spring beans This version leans heavily on the implementation-java classes

Version:
$Rev: 987670 $ $Date: 2010-08-21 00:42:07 +0100 (Sat, 21 Aug 2010) $
public class SpringBeanIntrospector {
The constructor sets up the various visitor elements that will be used to introspect the Spring bean and extract SCA information.

Parameters:
assemblyFactory The Assembly Factory to use
javaFactory The Java Interface Factory to use
policyFactory The Policy Factory to use.
        FactoryExtensionPoint factories = registry.getExtensionPoint(FactoryExtensionPoint.class);
    } // end constructor 

    
Introspect a Spring Bean and extract the features important to SCA

Parameters:
beanClass the Spring Bean class to introspect
componentType the componentType that is filled in through the introspection process (assumed empty on invocation, filled on return
Returns:
a Map of property names to JavaElementImpl
Throws:
org.apache.tuscany.sca.contribution.processor.ContributionResolveException - if there was a problem resolving the Spring Bean or its componentType
    public JavaImplementation introspectBean(Class<?> beanClassComponentType componentType)
        throws ContributionResolveException {
        if (componentType == null)
            throw new ContributionResolveException("Introspect Spring bean: supplied componentType is null");
        // Create a Java implementation ready for the introspection
        // Set the type to be implementation.spring to avoid heuristic introspection
        javaImplementation.setType(.);
        try {
            // Introspect the bean...the results of the introspection are placed into the Java implementation
            .createJavaImplementation(javaImplementationbeanClass);
            // Extract the services, references & properties found through introspection
            // put the services, references and properties into the component type
            componentType.getServices().addAll(javaImplementation.getServices());
            componentType.getReferences().addAll(javaImplementation.getReferences());
            componentType.getProperties().addAll(javaImplementation.getProperties());
        } catch (IntrospectionException e) {
            throw new ContributionResolveException(e);
        } // end try
        return javaImplementation;
    } // end method introspectBean
// end class SpringBeanIntrospector
