The library was designed to be asynchronous, but when needed we can simulate synchronous calls by blocking on theFutureobject. Bothexecute()andexecuteRequest()methods return aListenableFuture<Response>object. This class extends the JavaFutureinterface, thus inheriting theget()method, which can be us...
Asynchronous calls and remote callbacks using Lingo Spring Remoting As mentioned in mypreviousblog entry, Lingo is the only Spring Remoting implementation that supports asynchronous calls and remote callbacks. Today I'll cover all the nitty gritty details of the async/callback related functionality alon...

In synchronous calls, the request is sent using theexecute()method and the request is blocked and the response is available immediately to the next statement. In retrofit, synchronous methods are executed in the main thread. This means that theUI is blocked during the synchronous request execution...
Java Copy Code // makeApiRequestThenStoreResult contains the same code as the previous example CompletableFuture<String> result1 = makeApiRequestThenStoreResult(CUSTOMER_1); CompletableFuture<String> result2 = makeApiRequestThenStoreResult(CUSTOMER_2); // those calls are all happening in the ...
If the subscriber requests more than one data element each time it calls onNext(), request(10) for example, the publisher will send the next 10 elements immediately if they're available or when they become available. These elements accumulate in a buffer on the subscriber's end, and since ...
()method executes a GET request asynchronously and returns aplay.libs.F.Promise. The action method suspends the incoming HTTP request by callingawait(…)on the combination of the threePromiseinstances. When all three remote calls have a response, a thread will resume processing and render a ...
element. With a simple normalfororwhileloop this is impossible, when using callback functions, because the loop doesn't synchronize with asynchronous code. In the Async package, loops are expressed as library function calls with several callback functions representing different stages of loop ...
Common examples of such blocking operations are JDBC calls, streaming API, HTTP requests and long computations.Although it’s possible to increase the number of threads in the default execution context to allow more concurrent requests to be processed by blocking controllers, following the recommended...
Asynchronous Database Connectivity in Java (ADBCJ) ADBCJ allows you to access a relational database in a asynchronous, non-blocking fashion. The API is inspired by JDBC, but makes all calls asynchronous. The asynchronous access prevents any blocked threads, which just wait for the result of th...
