Description
A helper class to provide some basic mechanism of C++ reflection (introspection).
Properties of objects can be accessed/listed as name-value pairs. Names are those provided in the CHNVP pairs in ArchiveOut/ArchiveIn. As this is a quite simple reflection system, the value is always passed as void*, it is up to you to do the proper static_cast<> to the class of the object. There are some shortcuts though, to access double, int and other fundamental types with a single statement.

Member Function Documentation
◆ FetchValue()
|
inline |
Search a property in "root" and directly assign it to "vl".
The property is searched by the "property_name", returning true if it matches the names you used in the CHNVP macros of ArchiveOut of your classes, and if the type of "val" is the same of the property (exactly the same type: no superclass/subclass). Note: the "root" object should be a class with sub properties and/or sub objects, and the root is not part of the search. The search string "property_name" can explore subobjects with "/", as in "employee/force/z" The search string "property_name" can contain wildcards * and ?, as in "e??loyee/*‍/z" In case of multiple matching properties it returns at the first found property.
◆ FetchValues()
|
inline |
Search one or more values in "root" and return reference to a vector with results.
The properties are searched by the "value_name", returning true if it matches the names you used in the CHNVP macros of ArchiveOut of your classes Note: the "root" object should be a class with sub properties and/or sub objects, and the root is not part of the search. Wildcards * and ? can be used. For example use property_name = "*" to ge the list of all subproperties of root object.
◆ IsObject() [1/2]
|
inline |
Tell if "root" has sub values (i.e.
"root" is a class with ArchiveOut implemented or a std container such as std::vector).
◆ IsObject() [2/2]
|
inline |
Tell if "root" has sub values (i.e.
"root" is a class with ArchiveOut implemented or a std container such as std::vector).
