setPosition

                 throws IOException

Set the position of the stream pointer.

Throws:

setLimit

public void setLimit(int length)
              throws IOException

Description copied from interface: Limit

Set the limit of the data that can be read or written. After this call up to and including length bytes can be read from or skipped in the stream.

On input classes (e.g. InputStreams) any attempt to read or skip beyond the limit will result in an end of file indication (e.g. read() methods returning -1 or throwing EOFException).

On output classes (e.g. OutputStream) any attempt to write more beyond the limit will result in an EOFException

Specified by:

setLimit in interface Limit

Throws:

IOException - IOException from some underlying stream

clearLimit

public int clearLimit()

Description copied from interface: Limit

Clear any limit set by setLimit. After this call no limit checking will be made on any read until a setLimit()) call is made.

Specified by:

clearLimit in interface Limit

Returns:

the number of bytes within the limit that have not been read or written.
