Class Principal

java.lang.Object
  com.amazonaws.auth.policy.Principal

public class Principal
extends java.lang.Object

A principal is an AWS account or AWS web serivce, which is being allowed or denied access to a resource through an access control policy. The principal is a property of the Statement object, not directly the Policy object.

The principal is A in the statement "A has permission to do B to C where D applies."

In an access control policy statement, you can set the principal to all authenticated AWS users through the AllUsers member. This is useful when you don't want to restrict access based on the identity of the requester, but instead on other identifying characteristics such as the requester's IP address.
