Module: Adamantium::Mutable

Defined in:

lib/adamantium/mutable.rb

Overview

Module fake frozen object

This behavior sometimes is needed when a mutable object needs to be referenced in an inmutable object tree.

Use wisely! A rule of thumb only a tiny fraction of your objects typically deserves this.
