      • writeByte

        public void writeByte​(byte b)
                       throws java.io.IOException
        Description copied from class: DataOutput
        Writes a single byte.

        The most primitive data type is an eight-bit byte. Files are accessed as sequences of bytes. All other data types are defined as sequences of bytes, so file formats are byte-order independent.

        Specified by:
        writeByte in class DataOutput
        Throws:
        java.io.IOException
        See Also:
        DataInput.readByte()
      • writeBytes

        public void writeBytes​(byte[] src,
                               int offset,
                               int len)
                        throws java.io.IOException
        Description copied from class: DataOutput
        Writes an array of bytes.
        Specified by:
        writeBytes in class DataOutput
        Parameters:
        src - the bytes to write
        offset - the offset in the byte array
        len - the number of bytes to write
        Throws:
        java.io.IOException

      • getFilePointer

        public long getFilePointer()
        Description copied from class: IndexOutput
        Returns the current position in this file, where the next write will occur.
        Specified by:

      • getChecksum

        public long getChecksum()
                         throws java.io.IOException
        Description copied from class: IndexOutput
        Returns the current checksum of bytes written so far
        Specified by:
