示例1: get
Type
ProtocolConformanceRef::getTypeWitnessByName(Type type,
ProtocolConformanceRef conformance,
Identifier name,
LazyResolver *resolver) {
// For an archetype, retrieve the nested type with the appropriate
// name. There are no conformance tables.
if (auto archetype = type->getAs<ArchetypeType>()) {
return archetype->getNestedType(name);
}
// Find the named requirement.
AssociatedTypeDecl *assocType = nullptr;
auto members = conformance.getRequirement()->lookupDirect(name);
for (auto member : members) {
assocType = dyn_cast<AssociatedTypeDecl>(member);
if (assocType)
break;
}
// FIXME: Shouldn't this be a hard error?
if (!assocType)
return nullptr;
