Provides persistent classes you can use to examine class definitions, modify class definitions, create new classes, and even write programs that automatically generate documentation. There are two parallel sets of class definition classes: those that represent defined classes and those that represent compiled classes. For example, you can use %Dictionary.ClassDefinitionOpens in a new tab to work with class definitions, and you can use %Dictionary.CompiledClassOpens in a new tab to work with compiled classes.
There are similar classes in the %Library package, but the latter classes are deprecated.
