destination - Ausgabedatenstrom

closeOutput - Angabe ob der OutputStream nach dem Kopieren geschlossen werden soll.

Throws:

IOException - Fehler allgemein oder beim Kopieren.

                       throws IOException

Kopiert einen Stream. Ruft copyStream(in, true, out, true) auf.

Parameters:

source - Eingabedatenstrom, der kopiert werden soll.

destination - Ausgabestrom, auf den kopiert werden soll.

Throws:

IOException
