object-assoc

object-assoc is a compiled Lisp function in `eieio.el'.

(object-assoc KEY SLOT LIST)

Return an object if KEY is `equal' to SLOT's value of an object in LIST.
LIST is a list of objects whose slots are searched.
Objects in LIST do not need to have a slot named SLOT, nor does
SLOT need to be bound. If these errors occur, those objects will
be ignored.
