Interface AsyncInvocationInterceptor


public interface AsyncInvocationInterceptor
Implementations of this interface can intercept asynchronous method invocations. The MP Rest Client implementation runtime will obtain instances of this interface by invoking the newInterceptor method of all registered AsyncInvocationInterceptorFactory providers. The MP Rest Client implementation runtime will invoke the pre method on the main thread prior to returning execution back to the calling method of the client interface. The runtime will invoke the prepareContext method on the secondary thread before the client request is sent. The prepareContext method should always be invoked before the applyContext method is invoked, but due to the nature of multithreading, it is possible that applyContext method may be invoked before the prepareContext method has completed. Care should be taken when implementing this interface to avoid race conditions and deadlocks. Note that the order in which instances of the AsyncInvocationInterceptor are invoked are determined by the priority of the AsyncInvocationInterceptorFactory provider.

  • Method Details

    • prepareContext

      void prepareContext()
      This method will be invoked by the MP Rest Client runtime on the "main" thread (i.e. the thread calling the async Rest Client interface method) prior to returning control to the calling method.
    • applyContext

      void applyContext()
      This method will be invoked by the MP Rest Client runtime on the "async" thread (i.e. the thread used to actually invoke the remote service and wait for the response) prior to sending the request.
