    • window

      void window(int initialWindowSize)

    • incrementInitialStreamWindow

      void incrementInitialStreamWindow(int delta)
      Increment the initial window size for this stream.
      Parameters:
      delta - The amount to increase the initial window size by.

    • writeWindowUpdateIfNeeded

      boolean writeWindowUpdateIfNeeded() throws Http2Exception
      Updates the flow control window for this stream if it is appropriate.
      Returns:
      true if WINDOW_UPDATE was written, false otherwise.
      Throws:
      Http2Exception

    • consumeBytes

      boolean consumeBytes(int numBytes) throws Http2Exception
      Indicates that the application has consumed numBytes from the connection or stream and is ready to receive more data.
      Parameters:
      numBytes - the number of bytes to be returned to the flow control window.
      Returns:
      true if WINDOW_UPDATE was written, false otherwise.
      Throws:
      Http2Exception

    • unconsumedBytes

      int unconsumedBytes()

    • windowUpdateRatio

      float windowUpdateRatio()

    • windowUpdateRatio

      void windowUpdateRatio(float ratio)

    • receiveFlowControlledFrame

      void receiveFlowControlledFrame(int dataLength) throws Http2Exception
      A flow control event has occurred and we should decrement the amount of available bytes for this stream.
      Parameters:
      dataLength - The amount of data to for which this stream is no longer eligible to use for flow control.
      Throws:
      Http2Exception - If too much data is used relative to how much is available.

    • incrementFlowControlWindows

      void incrementFlowControlWindows(int delta) throws Http2Exception
      Increment the windows which are used to determine many bytes have been processed.
      Parameters:
      delta - The amount to increment the window by.
      Throws:
      Http2Exception - if integer overflow occurs on the window.

    • endOfStream
