> As a part of IGNITE-1816 I had to revisit our flags. Here are how they look now:
> {code}
> /** Flag: user type. */
> public static final short FLAG_USR_TYP = 0x0001;
> /** Flag: schema exists. */
> public static final short FLAG_HAS_SCHEMA = 0x0002;
> /** Flag indicating that object has raw data. */
> public static final short FLAG_HAS_RAW = 0x0004;
> /** Flag: offsets take 1 byte. */
> public static final short FLAG_OFFSET_ONE_BYTE = 0x0008;
> /** Flag: offsets take 2 bytes. */
> public static final short FLAG_OFFSET_TWO_BYTES = 0x0010;
> /** Flag: compact footer, no field IDs. */
> public static final short FLAG_COMPACT_FOOTER = 0x0020;
> {code}
> The following changes must be made to CPP:
> 1) When schema exists (i.e. at least on non-raw fieid was written), HAS_ SCHEMA flag is set to true. This is the inversed version of what previously was "RAW_ONLY".
> 2) When raw data exists, HAS_RAW flag is set to true. This flag should be used to determine location of raw data. 
> *DO NOT USE % for this anymore!*
> 3) For now COMPACT_FOOTER should always be 0. If you receive an object with this flag set to 1, an exception must be thrown.
