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.

#prepare_value(attr, value) ⇒ Object

Note:

Only array containers are wrapped. To automatically wrap values for attributes with hash containers a prepare hook should be used.

Wraps a value in an Array if needed and calls the prepare hook to allow further customization of a value before storing it in the instance variable.
