示例1: getResultType
static Type getResultType(TypeChecker &TC, FuncDecl *fn, Type resultType) {
// Look through optional types.
OptionalTypeKind optKind;
if (auto origValueType = resultType->getAnyOptionalObjectType(optKind)) {
// Get the interface type of the result.
Type ifaceValueType = getResultType(TC, fn, origValueType);
// Preserve the optional type's original spelling if the interface
// type is the same as the original.
if (origValueType.getPointer() == ifaceValueType.getPointer()) {
return resultType;
}
// Wrap the interface type in the right kind of optional.
switch (optKind) {
case OTK_None: llvm_unreachable("impossible");
case OTK_Optional:
return OptionalType::get(ifaceValueType);
case OTK_ImplicitlyUnwrappedOptional:
return ImplicitlyUnwrappedOptionalType::get(ifaceValueType);
}
llvm_unreachable("bad optional kind");
}
// Rewrite dynamic self to the appropriate interface type.
if (resultType->is<DynamicSelfType>()) {
return fn->getDynamicSelfInterface();
}
// Weird hacky special case.
if (!fn->getBodyResultTypeLoc().hasLocation() &&
fn->isGenericContext()) {
// FIXME: This should not be rewritten. This is only needed in cases where
// we synthesize a function which returns a generic value. In that case,
// the return type is specified in terms of archetypes, but has no TypeLoc
// in the TypeRepr. Because of this, Sema isn't able to rebuild it in
// terms of interface types. When interface types prevail, this should be
// removed. Until then, we hack the mapping here.
return TC.getInterfaceTypeFromInternalType(fn, resultType);
}
return resultType;
