2.2.5.1.1.1 Class

All SXAddl records (section 2.4.273.2) are grouped into classes. Each SXAddl record has a current class. An SXAddl record can be in other classes as well. The different classes and their specifications follow.

Unless the value of the hdr.sxc field of SXAddl is 0x09 and the value of the hdr.sxd field of SXAddl is 0xFF, the hdr.sxc field of the SXAddl record specifies the current class and MUST be a value from the following table:

Name	Value	Current Class
sxcView	0x00	SxcView class (section 2.2.5.1.1.1.1)
sxcField	0x01	SxcField class (section 2.2.5.1.1.1.2)
sxcHierarchy	0x02	SxcHierarchy class (section 2.2.5.1.1.1.3)
sxcCache	0x03	SxcCache class (section 2.2.5.1.1.1.4)
sxcCacheField	0x04	SxcCacheField class (section 2.2.5.1.1.1.5)
sxcQsi	0x05	SxcQsi class (section 2.2.5.1.1.1.6)
sxcQuery	0x06	SxcQuery class (section 2.2.5.1.1.1.7)
sxcGrpLevel	0x07	SxcGrpLevel class (section 2.2.5.1.1.1.8)
sxcGroup	0x08	SxcGroup class (section 2.2.5.1.1.1.9)
sxcCacheItem	0x09	SxcCacheItem class (section 2.2.5.1.1.1.10)
sxcSxrule	0x0C	SxcSXRule class (section 2.2.5.1.1.1.11)
sxcSxfilt	0x0D	SxcSXFilt class (section 2.2.5.1.1.1.12)
sxcSxdh	0x10	SxcSXDH class (section 2.2.5.1.1.1.13)
sxcAutoSort	0x12	SxcAutoSort class (section 2.2.5.1.1.1.14)
sxcSxmgs	0x13	SxcSXMgs class (section 2.2.5.1.1.1.15)
sxcSxmg	0x14	SxcSXMg class (section 2.2.5.1.1.1.16)
sxcField12	0x17	SxcField12 class (section 2.2.5.1.1.1.17)
sxcSxcondfmts	0x1A	SxcSXCondFmts class (section 2.2.5.1.1.1.18)
sxcSxcondfmt	0x1B	SxcSXCondFmt class (section 2.2.5.1.1.1.19)
sxcSxfilters12	0x1C	SxcSXFilters12 class (section 2.2.5.1.1.1.20)
sxcSxfilter12	0x1D	SxcSXFilter12 class (section 2.2.5.1.1.1.21)

The current class and the hdr.sxd field of SXAddl specify the full type of the record, see the individual classes for details.

If the value of the hdr.sxc field of SXAddl is 0x09 and the value of the hdr.sxd field of SXAddl is 0xFF, then the current class is specified by SxcCacheField class and the full record type is SXAddl_SXCCacheItem_SXDEnd (section 2.4.273.20).

Classes can be nested inside other classes in a hierarchical manner as specified by the Globals Substream (section 2.1.7.20.3) Augmented Backus-Naur Form (ABNF), Worksheet Substream (section 2.1.7.20.5) ABNF, and Common Productions (section 2.1.7.20.6) ABNF. Properties from the outer classes apply to the inner classes unless otherwise specified. Records in classes nested inside other classes, are members (1) of both the inner and outer classes, but their current class is given by the value of their hdr.sxc field. For example, SXAddl_SXCHierarchy_SXDProperty (section 2.4.273.57) is a member (1) of the SxcView class and the SxcHierarchy class and its current class is the SxcHierarchy class.
