Method Detail

• withContext

   final static <T extends Any> T withContext(ExecutionContextManager $self, String key, Object value, Function0<T> action)

  Executes given action in a way that ExecutionContextManager.getFromCurrentContext for the given key returns given value until the action is done.

• withContext

   final static <T extends Any> T withContext(ExecutionContextManager $self, Map<String, Object> context, Function0<T> action)

  Similar to withContext(String, Any?) but applies the bulk parameters.

• withCurrentContext

   final static <T extends Any> Function0<T> withCurrentContext(ExecutionContextManager $self, Function0<T> action)

  We might start processing in one thread and then continue in another thread, e.g. we might receive an event to process in one thread, queue and process it in a worker thread.

  That way a context set in the initial thread is lost in the second thread and we need to re-configure it explicitly.

  This method allows to decorate given action in a way that it's executed in the context which was active during this method's call time.

  Sample:

  executionContextManager.withContext("some-key", "some-value") {
      threadPool.submit(executionContextManager.withCurrentContext {
          println(executionContextManager.getFromCurrentContext("some-key")) // is guaranteed to print 'some-value'
      })
  }

• withCurrentContext

   final static <T extends Any, R extends Any> Function1<T, R> withCurrentContext(ExecutionContextManager $self, Function1<T, R> action)
