public interface Limit

Methods that allow limits to be placed on an input or output stream to avoid clients reading or writing too much information.

Method Summary
int	clearLimit()           Clear any limit set by setLimit.
void	setLimit(int length)           Set the limit of the data that can be read or written.

 

Method Detail

setLimit

public void setLimit(int length)
              throws java.io.IOException

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

---

clearLimit

public int clearLimit()

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