A "derived path" is a very simple sort of expression (not a Nix language expression! But an expression in a the general sense) that evaluates to (concrete) store path. It is either:
const StorePath & nix::SingleDerivedPath::getBaseStorePath | ( | ) | const |
Get the store path this is ultimately derived from (by realising and projecting outputs).
Note that this is not a property of the store object being referred to, but just of this path — how we happened to be referring to that store object. In other words, this means this function breaks "referential transparency". It should therefore be used only with great care.
