示例1: is_atom
bool is_atom(ast_manager & m, expr * n) {
if (is_quantifier(n) || !m.is_bool(n))
return false;
if (is_var(n))
return true;
SASSERT(is_app(n));
if (to_app(n)->get_family_id() != m.get_basic_family_id()) {
return true;
}
// the other operators of the basic family are not considered atomic: distinct, ite, and, or, iff, xor, not, implies.
return (m.is_eq(n) && !m.is_bool(to_app(n)->get_arg(0))) || m.is_true(n) || m.is_false(n);
