Example 1 with InvocationListener

use of org.apache.aries.proxy.InvocationListener in project aries by apache.

the class AbstractWovenProxyAdapter method writeFinalWovenProxyMethods.

/**
   * Write the methods we need for wovenProxies on the highest supertype
   */
private final void writeFinalWovenProxyMethods() {
    // add private fields for the Callable<Object> dispatcher
    // and InvocationListener. These aren't static because we can have
    // multiple instances of the same proxy class. These should not be
    // serialized, or used in JPA or any other thing we can think of,
    // so we annotate them as necessary
    generateField(DISPATCHER_FIELD, Type.getDescriptor(Callable.class));
    generateField(LISTENER_FIELD, Type.getDescriptor(InvocationListener.class));
    // a general methodAdapter field that we will use to with GeneratorAdapters
    // to create the methods required to implement WovenProxy
    GeneratorAdapter methodAdapter;
    // add a method for unwrapping the dispatcher
    methodAdapter = getMethodGenerator(PUBLIC_GENERATED_METHOD_ACCESS, new Method("org_apache_aries_proxy_weaving_WovenProxy_unwrap", DISPATCHER_TYPE, NO_ARGS));
    // /////////////////////////////////////////////////////

    // get the dispatcher field for the stack
    methodAdapter.getField(typeBeingWoven, DISPATCHER_FIELD, DISPATCHER_TYPE);
    // check if the dispatcher was non-null and goto return true if it was
    methodAdapter.ifNonNull(returnTrueLabel);
    methodAdapter.loadThis();
    // get the listener field for the stack
    methodAdapter.getField(typeBeingWoven, LISTENER_FIELD, LISTENER_TYPE);
    // check if the listener field was non-null and goto return true if it was

    methodAdapter.returnValue();
    // mark the returnTrueLable
    methodAdapter.mark(returnTrueLabel);
    methodAdapter.push(true);
    methodAdapter.returnValue();
    // end the method

the class ReferencesTest method testWiring.

    ProxyManager proxyManager = new AbstractProxyManager() {

        @Override
