## 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

    All Methods Instance Methods Abstract Methods
    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 `BackPressureState`s, and up to the given timeout.
    `S` | `newState(java.net.InetAddress host)` Creates a new `BackPressureState` initialized as needed by the specific implementation.

- - ### Method Detail

    - #### apply

          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 `BackPressureState`s, and up to the given timeout.

    - #### newState

          S newState(java.net.InetAddress host)

      Creates a new `BackPressureState` initialized as needed by the specific implementation.
