Defined in:

Overview

Allows to conveniently access a Specification programmatically.

It takes care of:

  • standardizing the attributes

  • handling multi-platform values

  • handle default values

  • handle automatic container wrapping of values

  • handle inherited values

This class allows to store the values of the attributes in the Specification as specified in the DSL. The benefits is reduced reliance on meta programming to access the attributes and the possibility of serializing a specification back exactly as defined in a file.
