# ClassifierAddClass

Create a class in a specified classifier.

A class represents one of the categories that you want to use to classify documents. For example, if you have a food classifier, you might have classes for vegetable, fruit, and meat.

When you create a class, you must set ClassifierName to the name of the classifier that you want to add the class to. You must also set ClassName to the name of the class that you want to add. You can optionally set StateID to specify a query state token that defines training documents for the class. Alternatively, you can train the class later by using the ClassifierSetClassTraining action.
