Interface Task<C extends FlowContext>

Type Parameters:

C - the type of the context shared between tasks

All Known Implementing Classes:

FindDomainController, FindNonProgressingTask, LoadSettings, ParallelTasks, ReadAuthentication, ReadEnvironment, ReadHostNames, ReadStabilityLevel, RegisterStaticCapabilities, RepeatTask, ResourceCheck, SequentialTasks, SetTitle, StartAnalytics

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.
