The Trio System

The Trio is the data structure and mechanisms that deal with discrete properties and filters.

It is a module-specific, three-level, (mostly) static construct that organizes options by categories/groups/options.

The Trio is responsible for:

• organizing the potentially large number of record properties in a managable structure.
• allowing groups to be dependent upon the selection of specific options.
• abstracting the different group types and their implementation details.

Please consult the Trio implementation documention below.
