class
RenderAttribRegistry
¶ This class is used to associate each
RenderAttrib
with a different slot index at runtime, so we can store a list ofRenderAttribs
in theRenderState
object, and very quickly look them up by type.Inheritance diagram

slots that have been allocated. This is one more than the highest slot number in use.

TypeHandle
, or 0 if no slot number has been assigned.

get_slot_default
(int slot) const¶ Returns the default
RenderAttrib
object associated with slot n. This is the attrib that should be applied in the absence of any other attrib of this type.
-
int
get_slot_sort
(int slot) const¶ Returns the sort number associated with slot n.
-
TypeHandle
get_slot_type
(int slot) const¶ Returns the
TypeHandle
associated with slot n.
-
int
get_sorted_slot
(int n) const¶ Returns the nth slot in sorted order. By traversing this list, you will retrieve all the slot numbers in order according to their registered sort value.
