◆ IsValid()
|
overridevirtual |
Description: Tests an object to see if its data members are correctly initialized. Parameters: text_log - [in] if the object is not valid and text_log is not nullptr, then a brief english description of the reason the object is not valid is appended to the log. The information appended to text_log is suitable for low-level debugging purposes by programmers and is not intended to be useful as a high level user interface tool. Returns: @untitled table true object is valid false object is invalid, uninitialized, etc.
