Nitro.Operator Class Reference

Detailed Description

Base class of all operators (+,- etc) and a global lookup for finding an operator instance from its text. When the system starts, all operators are automatically discovered by looking for any Operator classes. You can essentially create your own by simply deriving the Operator class.
