通过上一节的例子，在反射里加入数据成员，属性等，实现更加复杂的对象。
1.实现
1 #define DATAPROP(n) {&self::n,#n,0} 2 #define ATTRPROP(n) {&self::get##n,&self::set##n,#n,0} 3 #define FUNCPROP(n) {&self::n,#n,0} 4 class ObjectClass : public Object 5 { 6 DECL_RTTI(ObjectClass, Object); 7 DECL_TPLT(ObjectClass); 8 private: 9 static const ClassProperty& GetPropertys() 10 { 11 const static ClassProperty::BaseProperty bp[] = { &base::GetPropertys,vNull }; 12 const static DataProperty dp[] = 13 { 14 DATAPROP(intValue), 15 DATAPROP(blValue), 16 DATAPROP(sintValue), 17 DATAPROP(floatValue), 18 DataProperty() 19 }; 20 const static AttrProperty ap[] = 21 { 22 ATTRPROP(Int), 23 AttrProperty() 24 }; 25 const static FuncProperty fp[] = { FuncProperty() }; 26 const static ClassProperty prop(bp, dp, ap, fp); 27 return prop; 28 } 29 private: 30 int getInt()const { return intValue; } 31 void setInt(int i) { intValue = i; } 32 public: 33 int intValue; 34 bool blValue; 35 sint sintValue; 36 f32 floatValue; 37 }; 38 class ClassWithProperty : public Object 39 { 40 DECL_RTTI(ClassWithProperty, Object); 41 DECL_TPLT(ClassWithProperty); 42 public: 43 static const ClassProperty& GetPropertys() 44 { 45 const static ClassProperty::BaseProperty bp[] = { &base::GetPropertys,vNull }; 46 const static DataProperty dp[] = 47 { 48 DATAPROP(rawString), 49 DATAPROP(intValue), 50 DATAPROP(blValue), 51 DATAPROP(sintValue), 52 DATAPROP(floatValue), 53 DATAPROP(strValue), 54 DATAPROP(objClassPointer), 55 DATAPROP(objClassValue), 56 DataProperty() 57 }; 58 const static AttrProperty ap[] = 59 { 60 ATTRPROP(Int), 61 ATTRPROP(Bool), 62 ATTRPROP(Float), 63 ATTRPROP(String), 64 AttrProperty() 65 }; 66 const static FuncProperty fp[] = 67 { 68 {&self::getValString,"ValString",0}, 69 {&self::getPtrString,"PtrString",0}, 70 {&self::getRefString,"RefString",0}, 71 FuncProperty() 72 }; 73 const static ClassProperty prop(bp,dp,ap,fp); 74 return prop; 75 } 76 public: void displayProperty(int depth,const ClassProperty* props) 77 { 78 if (props == nullptr)return; 79 const DataProperty* dp = props->getDataProperty(); 80 while (dp->type != Type::vNone) 81 { 82 int n = depth; 83 while (n-- >= 0)LOG_P(" "); 84 LOG_P("%s %s\n", dp->type.getName(),dp->desc); 85 const Type currType = dp->type; 86 if (currType != Type::vNone) 87 { 88 displayProperty(depth + 1, currType.getPropertys()); 89 } 90 const Type* baseTypes = dp->type.getBaseTypes(); 91 while (*baseTypes != vNull) 92 { 93 displayProperty(depth + 1,baseTypes->getPropertys()); 94 baseTypes++; 95 } 96 dp++; 97 } 98 99 const AttrProperty* ap = props->getAttrProperty();100 while (ap->type != Type::vNone)101 {102 int n = depth;103 while (n-- >= 0)LOG_P(" ");104 LOG_P("%s %s\n", ap->type.getName(), ap->desc);105 const Type* baseTypes = ap->type.getBaseTypes();106 ap++;107 }108 109 const FuncProperty* fp = props->getFuncProperty();110 while (fp->type != Type::vNone) 111 {112 int n = depth;113 while (n-- >= 0)LOG_P(" ");114 LOG_P("%s %s\n", fp->type.getName(), fp->desc);115 const Type* baseTypes = fp->type.getBaseTypes();116 fp++;117 }118 }119 public:120 int getInt()const { return intValue; }121 void setInt(int i) { intValue = i; }122 bool getBool()const { return blValue; }123 void setBool(bool b) { blValue = b; }124 sint getLong()const { return sintValue; }125 void setLong(sint l) { sintValue = l; }126 f32 getFloat()const { return floatValue; }127 void setFloat(f32 f) { floatValue = f; }128 void setString(AString s) { strValue = s; }129 AString getString()const { return strValue; }130 public:131 const AString& getRefString(const AString& i)132 {133 LOG_P("RefString:%s\n", i.getRawString());134 static AString as = AtomString("atomString"); 135 return as;136 }137 const AString getValString(const AString i)138 {139 LOG_P("ValString:%s\n", i.getRawString());140 return AtomString("atomString"); 141 }142 const AString* getPtrString(const AString* i)143 { 144 LOG_P("PtrString:%s\n", i->getRawString());145 static AString as = AtomString("atomString"); return &as; 146 }147 private:148 char* rawString;149 AString strValue;150 int intValue;151 bool blValue;152 sint sintValue;153 f32 floatValue;154 ObjectClass* objClassPointer;155 ObjectClass objClassValue;156 };
2.使用
1 ClassWithProperty ct; 2 ct.displayProperty(0, &ct.getProperty()); 3 ct.DataMember["blValue"] = "true"; 4 bool bl = ct.DataMember["blValue"]; 5 std::cout << bl << std::endl; 6 ct.DataMember["objClassValue"]["intValue"] = "12"; 7 int rf = ct.DataMember["objClassValue"]["intValue"]; 8 std::cout << rf << std::endl; 9 Object& subObj = ct.DataMember["objClassValue"];10 subObj.DataMember["intValue"] = 13.5f;11 unsigned int rf2 = ct.DataMember["objClassValue"]["intValue"];12 std::cout << rf2 << std::endl;13 u32 iv = ct.DataMember["objClassValue"]["intValue"];14 std::cout << iv << std::endl;15 float rfu8 = ct.DataMember["objClassValue"]["intValue"];16 std::cout << rfu8 << std::endl;17 double rfud = ct.DataMember["objClassValue"]["intValue"];18 std::cout << rfud << std::endl;19 20 FuncProperty fp = ct.getProperty().getFuncProperty("ValString");21 AString s = fp.invoke (&ct,"value");22 LOG_P("ValString ret:%s\n", s.getRawString());23 24 fp = ct.getProperty().getFuncProperty("RefString");25 AString& rs = fp.invoke (&ct, &AString("reff"));26 LOG_P("RefString ret:%s\n", rs.getRawString());27 28 fp = ct.getProperty().getFuncProperty("PtrString");29 AString* ps = fp.invoke (&ct, &AString("pointer"));30 LOG_P("PtrString ret:%s\n", ps->getRawString()); 3.结果
