Examples of org.apache.tapestry5.ioc.Invokable

org.apache.tapestry5.ioc.Invokable
Similiar to {@link Runnable} execept that it returns a value. Used to represent any operation which can return avalue. This is often used in situations where the code is to be executed in another threads. @param < T> the return value type @see org.apache.tapestry5.ioc.OperationTracker#invoke(String,Invokable) @see org.apache.tapestry5.ioc.services.ParallelExecutor#invoke(Invokable)
