      • read

        public int read()
         throws java.io.IOException
        Reads the next byte of data from the input stream.
        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

      • read

        public int read​(byte[] aBarray)
         throws java.io.IOException

        Overrides:
        read in class java.io.InputStream
        Parameters:
        aBarray - the buffer into which the data is read.
        Returns:
        the total number of bytes read into the buffer, or -1 is there is no more data because the end of the stream has been reached.
        Throws:
        java.io.IOException - if an I/O error occurs. NullPointerException if aBarray is null

      • read

        public int read​(byte[] aBarray,
                int aOff,
                int aLen)
         throws java.io.IOException
        Reads up to aLen bytes of data from the input stream into an array of bytes.
        Overrides:
        read in class java.io.InputStream
        Parameters:
        aBarray - the buffer into which the data is read.
        aOff - the start offset in array aBarray at which the data is written.
        aLen - the maximum number of bytes to read.
        Returns:
        the total number of bytes read into the buffer, or -1 if there is no more data because the end of the stream has been reached.
        Throws:
        java.io.IOException - if an I/O error occurs.
        java.lang.NullPointerException - if aBarray is null.

      • skip

        public long skip​(long aN)
          throws java.io.IOException
        Skips over and discards n bytes of data from this stream.
        Overrides:
        skip in class java.io.InputStream
        Parameters:
        aN - the number of bytes to be skipped. Returns: the actual number of bytes skipped. Throws: IOException if an I/O error occurs.
        Returns:
        the actual number of bytes skipped.
        Throws:
        java.io.IOException - if an I/O error occurs

      • available

        public int available()
              throws java.io.IOException
        Returns the number of bytes that can be read (or skipped over) from this input stream without blocking by the next caller of a method for this input stream. The next caller might be the same thread or another thread.
        Overrides:
        available in class java.io.InputStream
        Returns:
        the number of bytes that can be read from this input stream without blocking.

      • close

        public void close()
           throws java.io.IOException
        Closes this input stream and releases any system resources associated with the stream.

        close in interface java.lang.AutoCloseable
        Specified by:
        close in interface java.io.Closeable
        Overrides:
        close in class java.io.InputStream

        java.io.IOException - if an I/O error occurs

      • mark

        public void mark​(int aReadLimit)
        Marks the current position in this stream. A subsequent call to the reset method repositions this stream at the last marked position so that subsequent reads re-read the same bytes.
        Overrides:
        mark in class java.io.InputStream
        Parameters:
        aReadLimit - the maximum limit of bytes that can be read before the mark position becomes invalid
        See Also:
        reset()

      • reset

        public void reset()
           throws java.io.IOException
        Repositions this stream to the position at the time the mark method was last called on this input stream
        Overrides:
        reset in class java.io.InputStream
        Throws:
        java.io.IOException - if this stream has not been marked or if the mark has been invalidated
        See Also:
        mark(int)

      • markSupported

        public boolean markSupported()
        Tests if this stream supports the mark and reset methods. Whether or not mark and reset are supported is an invariant property of the this stream instance.
        Overrides:
        markSupported in class java.io.InputStream
        Returns:
        true if this stream instance supports the mark and reset methods; false otherwise.
