      • read

        public int read()
         throws java.io.IOException
        Specified by:
        read in class java.io.InputStream
        Throws:
        java.io.IOException

      • read

        public int read​(byte[] b,
                int off,
                int len)
         throws java.io.IOException
        Reads up to len bytes of data from the input stream into an array of bytes.

        An attempt is made to read as many as len bytes, but a smaller number may be read. The number of bytes actually read is returned as an integer.

        This implementation may return 0 if the underlying SeekableByteChannel is non-blocking and currently hasn't got any bytes available.

        Overrides:
        read in class java.io.InputStream
        Throws:
        java.io.IOException
