-/**
- * The CopyStreamAdapter will relay CopyStreamEvents to a list of listeners

- * performed by one of the static copyStream() methods in
- * org.apache.commons.io.Util to multiple listeners. The static
- * copyStream() methods invoke the
- * bytesTransfered(long, int) of a CopyStreamListener for performance
- * reasons and also because multiple listeners cannot be registered given
- * that the methods are static.
