Overview

Top-Level namespace of all built-in Normatron filters.

All filters share some characteristics:

• They have the Filter suffix in the name.

• Has a class method called evaluate, which runs what the filter claims to do.

• The first argument of the method evaluate always will be the variable to be filtered.

• They returns a different object from the input variable, i.e., even if object value remains unchanged, the object_id will be different.

• They treat unicode characters(/\p{Ll}\p{Lu}/u) instead of only ASCII characters(/[a-zA-Z]/).
