Example 5 with Promise

use of io.joynr.provider.Promise in project joynr by bmwcarit.

the class ProviderWrapper method invoke.

/**
 * When a method is invoked via a joynr call, then it is delegated to an instance of the bean with which this
 * instance was initialised, if the method is part of the business interface and to this instance if it was part of
 * the {@link JoynrProvider} interface or the <code>Object</code> class.
 *
 * @param proxy
 *            the proxy object on which the method was called.
 * @param method
 *            the specific method which was called.
 * @param args
 *            the arguments with which the method was called.
 *
 * @return the result of the delegate method call on the EJB, but wrapped in a promise, as all the provider methods
 *         in joynr are declared that way.
