Member Data Documentation

◆ [struct]

struct { ... } SDNA::alias

Runtime versions of data stored in DNA, lazy initialized, only different when renaming is done.

Contains mapping from original (static) types/members names to their current (alias) DNA-defined versions (i.e. results from calling DNA_alias_maps with DNA_RENAME_ALIAS_FROM_STATIC).

◆ structs_num

int SDNA::structs_num

This covers all known structs from SDNA (pointers to SDNA_Struct data).

NOTE: See comment above about SDNA types above for differences between structs and types definitions. Number of struct definitions.

◆ types_alignment

int* SDNA::types_alignment

Alignment used when allocating pointers to this type. The actual minimum alignment of the type may be lower in some cases. For example, the pointer alignment of a single char is at least 8 bytes, but the alignment of the type itself is 1.

Definition at line 70 of file DNA_sdna_types.h.

Referenced by DNA_sdna_free(), DNA_struct_alignment(), and init_structDNA().

◆ types_num

int SDNA::types_num

This covers all known types (basic and structs ones) from SDNA.

NOTE: This data is not in sync with the SDNA structs info below. Among other things:

Basic types (int, float, etc.) have no matching struct definitions currently.
Types can be discovered and added before their struct definition, when they are used for members of another struct which gets parsed first. Number of types.

◆ types_to_structs_map

struct GHash* SDNA::types_to_structs_map

Mapping between type names (from types array above) and struct indices (into structs array above).

Requires WITH_DNA_GHASH to be used for now.

A version of SDNA.types_to_structs_map that uses SDNA.alias.types for its keys.
