Class CustomExecutionContext

Object

play.libs.concurrent.CustomExecutionContext

All Implemented Interfaces:

Executor, scala.concurrent.ExecutionContext, scala.concurrent.ExecutionContextExecutor

public abstract class CustomExecutionContext
extends Object
implements scala.concurrent.ExecutionContextExecutor

Provides a custom execution context from an Akka dispatcher.

Subclass this to create your own custom execution context, using the full path to the Akka dispatcher.

 class MyCustomExecutionContext extends CustomExecutionContext {
   // Dependency inject the actorsystem from elsewhere
   public MyCustomExecutionContext(ActorSystem actorSystem) {
     super(actorSystem, "full.path.to.my-custom-executor");
   }
 }
 

Then use your custom execution context where you have blocking operations that require processing outside of Play's main rendering thread.
