Class: N::Property

Overview

Ruby attributes are typeless and generally this is good. Some times we need extra metadata though, for example in relational mapping, or web form population.

Only Fixnums, Strings, Floats, Times, Booleans are converted.

The default = methods do not force the types. A special __force_set method should be used instead. – TODO: Perhaps a sync is needed in evals (!!!!) ++
