To ensure upward-compatibility, do not make assumptions about how information gets
returned. For example, do not assume that:
•
the offsets in the columns are in ascending order.
•
the null indicator offset, varlen offset, and data offset are within a contiguous range
without intervening fillers or data from other columns.
•
the data in the image info buffer is "dense," meaning that there are no unused
spaces in it.
•
the first field in the record starts at a fixed offset.
•
the values of nullIndLength_ and varLenLength_ are fixed at 2 and 4, respectively,
if non-zero.
•
fields in the image buffer that are not described by an MXARLibColumnInfo
structure are set to any given value.
