multifile_assertz/1
multifile_assertz(
+Clause)
Adds a compiled clause to the database. The clause will be added at the end of all existing clauses in the database.
If a predicate is multifile (compiled, interpreted-static or dynamic)
multifile_assertz/1
can be used to add a clause, Clause,
to the end of the predicate.
In a runtime system (see sap-srs), it is
an error to multifile_assertz
a
compiled clause because the compiler is not available.
If predicate is undefined at the time of the multifile_assertz
,
it is set to be compiled (in the
Development System) or dynamic (in a Runtime System).
In either case the predicate is also set to be multifile.
[Note that in runtime systems compile(
File)
actually loads the file as
all_dynamic
.]
Except for the case of a multifile dynamic predicate, the effect of
multifile_assertz
if used on a predicate that is currently
running will not be well-defined. The new clause may or may not be
seen on backtracking. If you want the proper semantics, use assertz
instead.
Same as assert/1
.
