    • getMaxTableCapacity

      public int getMaxTableCapacity()

    • setMaxTableCapacity

      public void setMaxTableCapacity(int maxTableCapacity)

      Sets the limit for the capacity of the dynamic header table.

      This value acts as a limit for the values received from the remote peer via the HPACK dynamic table size update instruction.

      After calling this method, a SETTINGS frame must be sent to the other peer, containing the SETTINGS_HEADER_TABLE_SIZE setting with the value passed as argument to this method.

      Parameters:
      maxTableCapacity - the limit for capacity of the dynamic header table

      @Deprecated public void setLocalMaxDynamicTableSize(int maxTableSizeLimit)
      Deprecated.
      use setMaxTableCapacity(int) instead
      Parameters:
      maxTableSizeLimit - the local dynamic table max size
