Modifier and Type	Method and Description
void	parallel(C context, Outcome<C> outcome, Function<C>... functions) Run an array of functions in parallel, without waiting until the previous function has completed.
void	series(Outcome outcome, Function... functions) Run an array of functions in series, each one running once the previous function has completed.
void	waterfall(C context, Outcome<C> outcome, Function<C>... functions) Runs an array of functions in series, working on a shared context.
void	whilst(Precondition condition, Outcome outcome, Function function) Repeatedly call function, while condition is met.
void	whilst(Precondition condition, Outcome outcome, Function function, int period) Same as whilst(Precondition, Outcome, Function) but waits period millis between calls to function.

Method Detail

series

public void series(Outcome outcome,
          Function... functions)

Run an array of functions in series, each one running once the previous function has completed. If any functions in the series pass an error to its callback, no more functions are run and outcome for the series is immediately called with the value of the error.

waterfall

@SafeVarargs
public final void waterfall(C context,
                         Outcome<C> outcome,
                         Function<C>... functions)

Runs an array of functions in series, working on a shared context. However, if any of the functions pass an error to the callback, the next function is not executed and the outcome is immediately called with the error.

parallel

public void parallel(C context,
            Outcome<C> outcome,
            Function<C>... functions)

Run an array of functions in parallel, without waiting until the previous function has completed. If any of the functions pass an error to its callback, the outcome is immediately called with the value of the error.

whilst

public void whilst(Precondition condition,
          Outcome outcome,
          Function function)

Repeatedly call function, while condition is met. Calls the callback when stopped, or an error occurs.

whilst

public void whilst(Precondition condition,
          Outcome outcome,
          Function function,
          int period)

Same as whilst(Precondition, Outcome, Function) but waits period millis between calls to function.

Parameters:

period - any value below 100 is ignored!
