Do methods process any roles or functions in the system?

Methods in programming themselves do not handle roles or functions in a system. Roles and functions are concepts of business logic or application architecture, which are implemented through methods, classes, and other structures. Methods perform specific actions or operations that may correspond to certain roles or functions, but methods themselves are just blocks of code. For example, a method may implement a function to check user permissions, but the user's role is determined at the level of business logic or data model.
