Detailed Description

General data used during a blend-file reading.

Note that this data (and its accesses) are absolutely not thread-safe currently. It should never be accessed concurrently.

◆ id_tag_extra

int FileData::id_tag_extra = 0

Tag to apply to all loaded ID data-blocks.

Note: This is initialized from LibraryLink_Params.id_tag_extra since passing it as an argument would need an additional argument to be passed around when expanding library data.

◆ libmap

OldNewMap* FileData::libmap = nullptr

Store mapping from old ID pointers (the values they have in the .blend file) to new ones, typically from value in bhead->old to address in memory where the ID was read. Used during library-linking process (see lib_link_all).

◆ new_idmap_uid

IDNameLib_Map* FileData::new_idmap_uid = nullptr

IDMap using uids as keys of the IDs read (or moved) in the new main(s).

Used during undo to ensure that the ID pointers from the 'no undo' IDs remain valid (these IDs are re-used from old main even if their content is not the same as in the memfile undo step, so they could point e.g. to an ID that does not exist in the newly read undo step).

Also used to find current valid pointers (or none) of these 'no undo' IDs existing in read memfile.

◆ old_idmap_uid

IDNameLib_Map* FileData::old_idmap_uid = nullptr

IDMap using UID's as keys of all the old IDs in the old bmain. Used during undo to find a matching old data when reading a new ID.

Definition at line 107 of file readfile.hh.

Referenced by blo_filedata_free(), read_file_dna(), and read_struct().

◆ relabase

char FileData::relabase[FILE_MAX] = {}

Used for relative paths handling.

Typically the actual filepath of the read blend-file, except when recovering save-on-exit/autosave files. In the latter case, it will be the path of the file that generated the auto-saved one being recovered.

NOTE: Currently expected to be the same path as BlendFileData.filepath.
