    • Method Detail

      • write

        void write​(byte[] b)
    throws java.io.IOException
        Writes b.length bytes from the specified byte array to this output at the current position.
        Parameters:
        b - the data.
        Throws:
        java.io.IOException - if an I/O error occurs.

      • write

        void write​(byte b)
    throws java.io.IOException
        Writes 1 byte to this output at the current position.
        Parameters:
        b - the data.
        Throws:
        java.io.IOException - if an I/O error occurs.

      • write

        void write​(java.nio.ByteBuffer b)
    throws java.io.IOException
        Writes b.remaining() bytes from the specified byte array to this output at the current position.
        Parameters:
        b - the data.
        Throws:
        java.io.IOException - if an I/O error occurs.

      • getPosition

        long getPosition()
          throws java.io.IOException
        gets the current position of the Output. This method is usually used for recording where the data is.
        For example, if the Output is a fileOutputStream, then getPosition returns its file position.
        Returns:
        current position
        Throws:
        java.io.IOException - if an I/O error occurs.

      • close

        void close()
    throws java.io.IOException
        close the output.
        Throws:
        java.io.IOException - if an I/O error occurs.

      • wrapAsStream

        java.io.OutputStream wrapAsStream()
                           throws java.io.IOException
        convert this TsFileOutput as a outputstream.
        Returns:
        an output stream whose position is the same with this Output
        Throws:
        java.io.IOException - if an I/O error occurs.

      • flush

        void flush()
    throws java.io.IOException
        the same with OutputStream.flush().
        Throws:
        java.io.IOException - if an I/O error occurs.

      • truncate

        void truncate​(long size)
       throws java.io.IOException
        The same with FileChannel.truncate(long).
        Parameters:
        size - size The new size, a non-negative byte count
        Throws:
        java.io.IOException
