struct Node {
std::string key;
int value;
std::vector<Node> children;
REFLECT() // Enable reflection for this type
};
REFLEC( ) 是：
define REFLECT() \
friend struct reflect::DefaultResolver; \
static reflect::TypeDescriptor_Struct Reflection; \
static void initReflection(reflect::TypeDescriptor_Struct*);
所以是在 structure 中增加一個 static variable 和 一個function
Reflection, initReflection()然後還有宣告
/ Define Node's type descriptor REFLECT_STRUCT_BEGIN(Node) REFLECT_STRUCT_MEMBER(key) REFLECT_STRUCT_MEMBER(value) REFLECT_STRUCT_MEMBER(children) REFLECT_STRUCT_END()就是依序把Node struct 的 member 宣告一下。
reflect::TypeDescriptor_Struct Node::Reflection{type::initReflection};
void Node::initReflection(reflect::TypeDescriptor_Struct* typeDesc) {
using T = Node;
typeDesc->name = "Node";
typeDesc->size = sizeof(Node);
typeDesc->members = {
{"key", offsetof(Node, key), reflect::TypeResolver<std:tring>::get()},
{"value", offsetof(Node, value), reflect::TypeResolver<int>::get()},
{"children", offsetof(Node, children), reflect::TypeResolver<std:vector<Node>>::get()},
};
}
main( ) 在告完 Node 變數後，就呼叫：
reflect::TypeDescriptor* typeDesc = reflect::TypeResolver<Node>::get();看一下 reflect::TypeResolver<Node>::get*()，template 展開
struct TypeResolver {
static TypeDescriptor* get() {
return DefaultResolver::get<Node>();
}
};
DefaultResolver:get 也是 template:
// This version is called if T has a static member named "Reflection":
template <typename T, typename std::enable_if<IsReflected<T>::value, int>::type = 0>
static TypeDescriptor* get() {
return &T::Reflection;
}
// This version is called otherwise:
template <typename T, typename std::enable_if<!IsReflected<T>::value, int>::type = 0>
static TypeDescriptor* get() {
return getPrimitiveDescriptor<T>();
}
先解開
template <typename T, typename std::enable_if<IsReflected<T>::value, int>::type = 0>用 std::enable_if 來區分要用那一個
std::enable_if<IsReflected<T>::value, int>::type = 0enable_if 的 boolean 是 IsRlected<T>::value
struct IsReflected {
enum { value = (sizeof(func<T>(nullptr)) == sizeof(char)) };
};
value 的值是 true or false:
(sizeof(func<T>(nullptr)) == sizeof(char))func<T>(nullptr) 有兩個定義，由 T 沒有 member variable : Reflection 決定。Node 有，所以func 是..
template <typename T> static char func(decltype(&T::Reflection));所以是sizeof(char)，所以 value 是 true，也就是 IsReflected<Node>::value 是 true
template <typename T, typename std::enable_if<IsReflected<T>::value, int>::type = 0>
static TypeDescriptor* get() {
return &T::Reflection;
}
所以是main( ) 中呼叫 :: get( ) 會回傳，Node::Reflection
virtual void dump(const void* obj, int indentLevel) const override {
std::cout << name << " {" << std::endl;
for (const Member& member : members) {
std::cout << std::string(4 * (indentLevel + 1), ' ') << member.name << " = ";
member.type->dump((char*) obj + member.offset, indentLevel + 1);
std::cout << std::endl;
}
std::cout << std::string(4 * indentLevel, ' ') << "}";
}
