{{Edited|July|12|2025}}
The <code>ClassFromString</code> operator allows you to treat a string as a model type (OclType). When "going meta" with your model, you can use <code>AsString</code> to convert a type to a string, and <code>ClassFromString</code> to perform the inverse operation—converting that string back into an actionable type.

This is particularly useful when you need to query model metadata or filter subclasses based on naming conventions or tagged values stored as strings.

=== Syntax ===
 string.ClassFromString
Example
 Customer.allSubClasses->select(x|x.classfromstring.TaggedValue('status')<>'Obsolete')
This returns a collection of class strings where the actual underlying class does not have the "Obsolete" tag.
