    - #### CopyStreamEvent

          public CopyStreamEvent(Object source,
                         long totalBytesTransferred,

                         long streamSize)

      Creates a new CopyStreamEvent instance.
      Parameters:
        `source` - The source of the event.
        `totalBytesTransferred` - The total number of bytes transferred so far during a copy operation.
        `bytesTransferred` - The number of bytes transferred during the write that triggered the CopyStreamEvent.
        `streamSize` - The number of bytes in the stream being copied. This may be set to `UNKNOWN_STREAM_SIZE` if the size is unknown.
