https://github.com/apache/nifi-minifi-cpp/pull/453
Overview:
-Please read tests first. They should give an idea of the motivation of the
change
-This is POF, some parts of the code might leave space for improvement,
some are not yet implemented.
Pros of suggested solution:
-Fully backward-compatible, no change required in processors.
-All property types can be assigned to Property (string property) without
loosing the validator.
-Values are still stored in string, so no change in overhead of getter
-Easily extendable with further validators, properties
-Validators can provide data in any format for server-side validation, no
duplication of data
Cons:
-Templates, templates, templates everywhere... Added some static asserts to
help development with meaningful error messages.
