Abstract Document Pattern
open-in-new
<p>An object-oriented <a href="/facts/Structural_pattern/xLyRr02K">structural design pattern</a> for organizing objects in loosely typed key-value stores and exposing the data using typed views. The purpose of the pattern is to achieve a high degree of flexibility between components in a <a href="/facts/Strong_and_weak_typing/WYexudnr">strongly typed language</a> where new properties can be added to the object-tree on the fly, without losing the support of type-safety. The pattern makes use of <a href="/facts/Trait_(computer_programming)/olRmTbFe">traits</a> to separate different properties of a class into different interfaces. The term "document" is inspired from <a href="/facts/Document-oriented_database/ttVRBHG4">document-oriented databases</a>. </p>
