Interface Flow

public interface Flow
An interface to execute a list of asynchronous tasks in parallel or sequentially, or to execute a single task repeatedly as long as certain conditions are met.

The tasks share a context that can be used to store data in a map or on a stack.

  • Method Details

    • parallel

      static <C extends FlowContext> Sequence<C> parallel(C context, List<Task<C>> tasks)
      Executes a list of asynchronous tasks in parallel (all at once).
      Type Parameters:
      C - the type of the shared context
      Parameters:
      context - the context shared between tasks
      tasks - the list of tasks to execute in parallel
      Returns:
      an interface to control whether the execution of the tasks should fail fast or fail last

    • sequential

      static <C extends FlowContext> Sequence<C> sequential(C context, List<Task<C>> tasks)
      Executes a list of asynchronous tasks in sequence (one after the other).
      Type Parameters:
      C - the type of the shared context
      Parameters:
      context - the context shared between tasks
      tasks - the list of tasks to execute in order
      Returns:
      an interface to control whether the execution of the tasks should fail fast or fail last

    • repeat

      static <C extends FlowContext> Repeat<C> repeat(C context, Task<C> task)
      Executes the given task repeatedly as long as the conditions defined by Repeat are met.
      Type Parameters:
      C - the type of the shared context
      Parameters:
      context - the context shared between the iterations
      task - the task to execute while the predicate evaluates to true
      Returns:
      an interface to control the interval, timeout and fail fast behaviour
