Sourcedynamic(:ListOfPredicateIndicators, +Options)
As dynamic/1, but allows for setting additional properties. This predicate allows for setting multiple properties on multiple predicates in a single call. SWI-Prolog also offers the XSB compatible :- dynamic (p/1) as (incremental,abstract(0)). syntax. See the introduction of section 4.15. Defined Options are:
incremental(+Boolean)
Make the dynamic predicate signal depending tables. See section 7.7.
abstract(0)
This option must be used together with incremental. The only supported value is 0. With this option a call to the incremental dynamic predicate is recorded as the most generic term for the predicate rather than the specific variant.
thread(+Local)
Local is one of shared (default) or local. See also thread_local/1.
multifile(+Boolean)
discontiguous(+Boolean)
volatile(+Boolean)
Set the corresponding property. See multifile/1, discontiguous/1 and volatile/1.
