// All derived attribute types implement at least getter/setter for their own type (like CBoolAttribute will have setBool/getBool).
|
|
// Simple types will also implement getStringW and setString, but don't expect it to work for all types.
|
|
// String serialization makes no sense for some attribute-types (like stringw arrays or pointers), but is still useful for many types.
|
|
// (Note: I do _not_ know yet why the default string serialization is asymmetric with char* in set and wchar_t* in get).
|
|
// Additionally many attribute types will implement conversion functions like CBoolAttribute has p.E. getInt/setInt().
|
|
// The reason for conversion functions is likely to make reading old formats easier which have changed in the meantime. For example
|
|
// an old xml can contain a bool attribute which is an int in a newer format. You can still call getInt() even thought the attribute has the wrong type.
|
|
// And please do _not_ confuse these attributes here with the ones used in the xml-reader (aka SAttribute which is just a key-value pair).
