Direct Known Subclasses:

public abstract class EncryptorOutputStream
extends CryptoOutputStream

Provides a certain level of type safety for instantiating classes. All encryptors will only provide output stream capabilites and hence it only extends from CryptoOutputStream.

Method Detail

flush

public void flush(boolean pad)
           throws IOException

Flushes any pending data to the stream and, optionally, does any necessary padding correctly. A subclass should override this function if they have padding they need done.

This function is useful if you wish to re-use this object and so require that the previously written data have any necessary padding completed for it.

Parameters:

pad - If true, then perform the appropriate padding code ( if necessary - stream ciphers don't require this ) Otherwise, just flush normally.

Throws:

IOException
