Expdata-surjmapp
Information about a surjective mapping according to which
(some of) the target function's arguments and results
are transformed.
(expdata-surjmapp x) is a std::defaggregate of the following fields.
- surjname — Name of the defsurj.
Invariant (symbolp surjname).
- localp — Flag saying whether the defsurj is
locally generated or not.
Invariant (booleanp localp).
- oldp — Recognizer of the old representation,
i.e. the domb domain of the defsurj.
Invariant (pseudo-termfnp oldp).
- newp — Recognizer of the new representation,
i.e. the doma domain of the defsurj.
Invariant (pseudo-termfnp newp).
- forth — Conversion from old to new representation,
i.e. the beta conversion of the defsurj.
Invariant (pseudo-termfnp forth).
- back — Conversion from new to old representation,
i.e. the alpha conversion of the defsurj.
Invariant (pseudo-termfnp back).
- forth-image — Name of the :beta-image theorem of the defsurj.
Invariant (symbolp forth-image).
- back-image — Name of the :alpha-image theorem of the defsurj.
Invariant (symbolp back-image).
- back-of-forth — Name of the :alpha-of-beta theorem
of the defsurj.
Invariant (symbolp back-of-forth).
- forth-injective — Name of the :beta-injective theorem
of the defsurj.
Invariant (symbolp forth-injective).
- oldp-guard — Name of the :domb-guard theorem
of the defsurj, if present (otherwise nil).
Invariant (symbolp oldp-guard).
- newp-guard — Name of the :doma-guard theorem
of the defsurj, if present (otherwise nil).
Invariant (symbolp newp-guard).
- forth-guard — Name of the :beta-guard theorem
of the defsurj, if present (otherwise nil).
Invariant (symbolp forth-guard).
- back-guard — Name of the :alpha-guard theorem
of the defsurj, if present (otherwise nil).
Invariant (symbolp back-guard).
- hints — Optional hints for the defsurj,
if locally generated (otherwise nil).
Invariant (keyword-value-listp hints).

This aggregate is somewhat similar to defmapping-infop,
and in fact it corresponds
either to an existing defsurj that is referenced
in an surjk input of expdata,
or to a locally generated defsurj that is determined
in the surjk input of expdata.
However, this aggregate is not stored in any table;
it has some fields in common (except for their names)
with defmapping-infop,
but it has a few extra fields and omits a few fields.
This aggregate is only for expdata's internal use.
Note that there are no forth-of-back and back-injective theorems,
because the corresponding theorems are not in the defsurj.
