Interface BackPressureStrategy<S extends BackPressureState>

All Known Implementing Classes:

RateBasedBackPressure

public interface BackPressureStrategy<S extends BackPressureState>

Back-pressure algorithm interface.
For experts usage only. Implementors must provide a constructor accepting a single Map<String, Object> argument, representing any parameters eventually required by the specific implementation.

Method Summary

Modifier and Type	Method and Description
void	apply(java.util.Set<S> states, long timeout, java.util.concurrent.TimeUnit unit) Applies the back-pressure algorithm, based and acting on the given BackPressureStates, and up to the given timeout.
S	newState(java.net.InetAddress host) Creates a new BackPressureState initialized as needed by the specific implementation.
