public final class RenewableCipherLiteInputStream
extends CipherLiteInputStream

A specific kind of CipherLiteInputStream that supports partial mark-and-reset in the sense that, if the underlying input stream supports mark-and-reset, this input stream can then be marked at and get reset back to the very beginning of the stream (but not anywhere else).

Method Detail

markSupported

public boolean markSupported()

Mark and reset is currently only partially supported, in the sense that, if the underlying input stream supports mark-and-reset, this input stream can then be marked at and get reset back to the very beginning of the stream (but not anywhere else).

Overrides:

markSupported in class CipherLiteInputStream

mark

public void mark(int readlimit)

Mark and reset is currently only partially supported, in the sense that, if the underlying input stream supports mark-and-reset, this input stream can then be marked at and get reset back to the very beginning of the stream (but not anywhere else).

Overrides:

mark in class CipherLiteInputStream

Throws:

UnsupportedOperationException - if mark is called after this stream has been accessed.

reset

public void reset()
           throws IOException

Resets back to the very beginning of the stream.

Mark and reset is currently only partially supported, in the sense that, if the underlying input stream supports mark-and-reset, this input stream can then be marked at and get reset back to the very beginning of the stream (but not anywhere else).

Overrides:

reset in class CipherLiteInputStream

Throws:

IOException

         throws IOException

Overrides:
