                       throws IOException

Kopiert einen Eingabedatenstrom auf einen Ausgabedatenstrom. Anschließend (finally) werden die Datenströme geschlossen(!), sofern dies in den Parametern angegeben wurde. Fehler beim Schließen der Datenströme werden ignoriert.

Parameters:

source - Eingabedatenstrom

destination - Ausgabedatenstrom

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

Throws:

IOException - Fehler allgemein oder beim Kopieren.

copyStream

public static void copyStream(InputStream source,
              OutputStream destination)
                       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
