// PropertyReader is a class concept that requires the following method:
28
//   BasicReader find(llvm::StringRef propertyName);
29
// where BasicReader is some class conforming to the BasicReader concept.
30
// An abstract AST-node reader is created with a PropertyReader and
31
// performs a sequence of calls like so:
32
//   propertyReader.find(propertyName).read##TypeName()
33
// to read the properties of the node it is deserializing.
34
35
// BasicReader is a class concept that requires methods like:
36
//   ValueType read##TypeName();
37
// where TypeName is the name of a PropertyType node from PropertiesBase.td
38
// and ValueType is the corresponding C++ type name.  The read method may
39
// require one or more buffer arguments.
40
//
41
// In addition to the concrete type names, BasicReader is expected to
42
// implement these methods:
43
//
44
//   template <class EnumType>
45
//   void writeEnum(T value);
46
//
47
//     Reads an enum value from the current property.  EnumType will always
48
//     be an enum type.  Only necessary if the BasicReader doesn't provide
49
//     type-specific readers for all the enum types.
50
//
51
//   template <class ValueType>
52
//   Optional<ValueType> writeOptional();
53
//
54
//     Reads an optional value from the current property.
55
//
56
//   template <class ValueType>
57
//   ArrayRef<ValueType> readArray(llvm::SmallVectorImpl<ValueType> &buffer);
58
//
59
//     Reads an array of values from the current property.
60
//
61
//   PropertyReader readObject();
62
//
63
//     Reads an object from the current property; the returned property
64
//     reader will be subjected to a sequence of property reads and then
65
//     discarded before any other properties are reader from the "outer"
66
//     property reader (which need not be the same type).  The sub-reader
67
//     will be used as if with the following code:
68
//
69
//       {
70
//         auto &&widget = W.find("widget").readObject();
71
//         auto kind = widget.find("kind").readWidgetKind();
72
//         auto declaration = widget.find("declaration").readDeclRef();
73
//         return Widget(kind, declaration);
74
//       }
75
76
// ReadDispatcher does type-based forwarding to one of the read methods
77
// on the BasicReader passed in:
78
//
79
// template <class ValueType>
80
// struct ReadDispatcher {
81
//   template <class BasicReader, class... BufferTypes>
82
//   static ValueType read(BasicReader &R, BufferTypes &&...);
83
// };
84
85
// BasicReaderBase provides convenience implementations of the read methods
86
// for EnumPropertyType and SubclassPropertyType types that just defer to
87
// the "underlying" implementations (for UInt32 and the base class,
88
// respectively).
