|
|
* This enum defines the index assigned to each type of IDs in the array returned by
|
|
* #set_listbasepointers, and by extension, controls the default order in which each ID type is
|
|
* processed during standard 'foreach' looping over all IDs of a #Main data-base.
|
|
*
|
|
* About Order:
|
|
* ------------
|
|
*
|
|
* This is (loosely) defined with a relationship order in mind, from lowest level (ID types using,
|
|
* referencing almost no other ID types) to highest level (ID types potentially using many other ID
|
|
* types).
|
|
*
|
|
* So e.g. it ensures that this dependency chain is respected:
|
|
* #Material <- #Mesh <- #Object <- #Collection <- #Scene
|
|
*
|
|
* Default order of processing of IDs in 'foreach' macros (#FOREACH_MAIN_ID_BEGIN and the like),
|
|
* built on top of #set_listbasepointers, is actually reversed compared to the order defined here,
|
|
* since processing usually needs to happen on users before it happens on used IDs (when freeing
|
|
* e.g.).
|
|
*
|
|
* DO NOT rely on this order as being full-proofed dependency order, there are many cases were it
|
|
* can be violated (most obvious cases being custom properties and drivers, which can reference any
|
|
* other ID types).
|
|
*
|
|
* However, this order can be considered as an optimization heuristic, especially when processing
|
|
* relationships in a non-recursive pattern: in typical cases, a vast majority of those
|
|
* relationships can be processed fine in the first pass, and only few additional passes are
|
|
* required to address all remaining relationship cases.
|
|
* See e.g. how #BKE_library_unused_linked_data_set_tag is doing this.
