Retrieving predefined attributes

— retrieving predefined attributes of various types

The subscriber class definition for the first tutorial included a single predefined attribute, Message:

message = n.getPredefinedAttrString("Message");

The new subscriber class definition includes three more predefined attributes: UserName, Age, and Gender:

username = n.getPredefinedAttrString("UserName");

age = n.getPredefinedAttrLong("Age");

gender = n.getPredefinedAttrChar("Gender");

In the first part of this tutorial, Common Cases, Publication — Java, we set the values for these predefined attributes.
