We propose to add APIs to the JPPFJob class, in order to allow tasks as lambda expressions.

For example, for Callable and Runnable tasks:

public Task<?> addRunnable(JPPFRunnableTask task);
 
public <T> Task<?> addCallable(JPPFCallable<T> task);

where JPPFRunnableTask is defined as:

public class JPPFRunnableTask extends Runnable, Serializable { }

and JPPFCallable is defined as:

public class JPPFCallable<T> extends Callable<T>, Serializable { }

We need to ensure the tasks are serializable.

We could then add a callable task as a lambda expression, such as:

JPPFJob job = new JPPFJob();
job.addCallable(() -> "hello, world");
