class pyre.traits.Trait.Trait

Bases: pyre.descriptors.stem.variable, pyre.framework.Dashboard.Dashboard

This is the base class for component features that form their public interface

Traits extend the notion of a class attribute to an object that is capable of capturing information about the attribute that has no natural resting place as part of a normal class declaration.

Traits enable end-user configurable state, for both simple attributes and references to more elaborate objects, such as other components. Individual inventory items need a name that enables access to the associated information, per-instance actual storage for the attribute value, and additional meta data, such as reasonable default values when the attribute is not explicitly given a value during configuration, and the set of constraints it should satisfy before it is considered a legal value.
