    • decohereOutputKey

      public void decohereOutputKey(K key, KeyEffect effect)
      Description copied from interface: MapInlet
      Marks this MapInlet as needing an effect applied to a given key. Decohering an individual key decoheres the entire state of the Inlet. But only the decoherent keys need to be updated in order to recohere the overall state of the Inlet.
      Specified by:
      decohereOutputKey in interface MapInlet<K,VI,VO>

    • decohereInputKey

      public void decohereInputKey(K key, KeyEffect effect)
      Description copied from interface: MapOutlet
      Marks this MapOutlet as needing an effect applied to a given key. Decohering an individual key decoheres the entire state of the Outlet. But only the decoherent keys need to be updated in order to recohere the overall state of the Outlet.
      Specified by:

    • decohereKey

      public void decohereKey(K key, KeyEffect effect)

    • decohereOutput

      public void decohereOutput()
      Description copied from interface: Inlet
      Marks this Inlet—and the Streamlet to which this Inlet is attached—as having decoherent state. Decohering an Inlet will recursively decohere all streamlets that transitively depend on the state of this Inlet. Decohering an Inlet does not cause its state to be recomputed. A subsequent Inlet.recohereOutput(int) call will eventually make the state of the Inlet coherent again.
      Specified by:
      decohereOutput in interface Inlet<K>

    • decohereInput

      public void decohereInput()
      Description copied from interface: Outlet
      Marks this Outlet—and all outputs that depend on the state of this Outlet—as having decoherent state.
      Specified by:
      decohereInput in interface Outlet<K>

    • decohere

      public void decohere()

    • recohereOutputKey

      public void recohereOutputKey(K key, int version)
      Description copied from interface: MapInlet
      Updates the state of an individual key in this MapInlet to make it consistent with the target version. The MapInlet only needs to update if the current version differs from the target version. To update the state of a key, the MapInlet first invokes MapOutlet.recohereInputKey(Object, int) on its input, if its input is a MapOutlet, or it invokes Outlet.recohereInput(int), if its input is not a MapOutlet. Then, if all decoherent keys have been recohered, the MapInlet invokes Streamlet.recohere(int) on its attached streamlet.
      Specified by:
      recohereOutputKey in interface MapInlet<K,VI,VO>

    • recohereInputKey

      public void recohereInputKey(K key, int version)
      Description copied from interface: MapOutlet
      Updates the state of an individual key in this MapOutlet to make it consistent with the target version. The MapOutlet only needs to update if its current version differs from the target version. To update the state of a key, the MapOutlet first invokes Streamlet.recohere(int) on its attached streamlets. Then, for each dependent output, it invokes MapInlet.recohereOutputKey(Object, int), if the dependent output is a MapInlet, or it invokes Inlet.recohereOutput(int), if the dependent output is not a MapInlet.
      Specified by:
      recohereInputKey in interface MapOutlet<K,VI,VO>

    • recohereKey

      public void recohereKey(K key, int version)

    • recohereOutput

      public void recohereOutput(int version)
      Description copied from interface: Inlet
      Updates the state of this Inlet to make it consistent with the target version. The Inlet only needs to update if its current version differs from the target version. To update its state, the Inlet first invokes Outlet.recohereInput(int) on its input, to ensure that its input is coherent. It then invokes Streamlet.recohere(int) on the Streamlet to which it's attached, causing the Streamlet to make its own state coherent again.
      Specified by:
      recohereOutput in interface Inlet<K>

    • recohereInput

      public void recohereInput(int version)
      Description copied from interface: Outlet
      Updates the state of this Outlet to make it consistent with the target version. The Outlet only needs to update if its current version differs from the target version. To update its state, the Outlet first invokes Streamlet.recohere(int) on the Streamlet to which it's attached. It then invokes Inlet.recohereOutput(int) on each of its dependent outputs.
