/**
* This class is intended to application developers willing to translate "C" application code
* which makes use of ta_abstract.h.
*
* In Java, applications and API make a wide use of exceptions whilst in "C" code the common approach is returning status
* codes. This class adds a layer over class CoreMetaData which handles and consumes exceptions and, instead of exceptions,
* returns status codes.
*
* IMPORTANT: This class is provided as it is by the author as a starting point for "C" application code translators.
* Use this class on your own risk as this class was not tested by the author.
*
*
IMPORTANT: Some methods from ta_abstract.h where not implemented. The author do not intend to
* provide these methods as there's low or even no interest on this kind of compatibility mode. As already said, this is
* only a starting point for applications translators which could be interested to further improve this class.
