      • close

        public void close()
                   throws java.io.IOException
        Specified by:
        close in interface java.lang.AutoCloseable
        Specified by:
        close in interface java.io.Closeable
        Overrides:
        close in class java.io.InputStream
        Throws:
        java.io.IOException
      • read

        public int read()
                 throws java.io.IOException
        Reads the next byte of data from the input stream. The value byte is returned as an int in the range 0 to ASCII_MAX. If no byte is available because the end of the stream has been reached, the value -1 is returned. This method blocks until input data is available, the end of the stream is detected, or an exception is thrown.

        UTF-16 characters above ASCII_MAX produce a NON_ASCII_REPLACEMENT value when read.

        Surrogate pairs are correctly counted as a single character and produce a single NON_ASCII_REPLACEMENT value when read.

        Specified by:
        read in class java.io.InputStream
        Returns:
        the next byte of data, or -1 if the end of the stream is reached.
        Throws:
        java.io.IOException - if an I/O error occurs.
