Task (Elemento Flow 1.5.0 API)

Type Parameters:

C - the type of the context shared between tasks

All Known Implementing Classes:

ParallelTasks, RepeatTask, SequentialTasks

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@FunctionalInterface
public interface Task<C extends FlowContext>
```
Interface for the execution of an asynchronous task.
Task implementations can use FlowContext.resolve(), FlowContext.resolve(Object) and FlowContext.resolve(String, Object) as a shortcut to push or put a value on the stack or the map and return a resolved promise.
In case of an error task implementations can use FlowContext.reject(Object) to return a rejected promise. Rejected promises are caught by the enclosing Flow methods and returned as a resolved promise.
