public final class RenewableCipherInputStream
extends CipherInputStream

A specific kind of CipherInputStream 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).

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).

覆盖:

markSupported 在类中 CipherInputStream

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).

覆盖:

抛出:

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.
