      • setLimit

        public void setLimit​(int length)
              throws java.io.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:
        java.io.IOException - IOException from some underlying stream
        java.io.EOFException - The set limit would exceed the available data in the 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.
