Predicate rb_map/3 |
call(G,Val0,ValF)
holds, then the
value associated with Key in NewTree is ValF. Fails if
call(G,Val0,ValF)
is not satisfiable for all Val0. If G is
non-deterministic, rb_map/3 will backtrack over all possible values
from call(G,Val0,ValF)
. You should not depend on the order of tree
traversal (currently: key order).
