Detailed Description

Wrapper class for different type objects

Supports both class objects(string, vector, TRestMetadata, etc.) and basic type objects(int, double, etc.). Implements object wrapping, type assembly, data member reflection, memory streaming, and string conversion. We set a type alias any for this class.

Example 1: Type assembly & Value assignment

TRestEventProcess* proc = REST_Reflection::Assembly("TRestRawSignalAnalysisProcess");
proc->PrintMetadata();
any member = REST_Reflection::GetDataMember(obj, "fIntegralRange");
TVector2 v(10, 50);
member.SetValue(v);
proc->PrintMetadata();

Example 2: Object wrapping & Memory streaming

map<int, double> a{{6, 1.4}, {7, 1.23}};
map<int, double> b;
ToString(any(a));    // returns string: "map<int,double> @0x7f2b03ff0038"
any(a) >> any(b);     // copy a's data to b
b[6]; // we can get value 1.4

Example 3: Convert to string

TVector2 a(1,3);
ToString(a);          // shows the string "(1,3)"
vector<int> b{3,5,7,9,2};
cout << any(b) << endl;   // prints the content of b in string: "{3,5,7,9,2}"
