Examples of java.security.ProtectionDomain

java.security.ProtectionDomain

This ProtectionDomain class encapsulates the characteristics of a domain, which encloses a set of classes whose instances are granted a set of permissions when being executed on behalf of a given set of Principals.
A static set of permissions can be bound to a ProtectionDomain when it is constructed; such permissions are granted to the domain regardless of the Policy in force. However, to support dynamic security policies, a ProtectionDomain can also be constructed such that it is dynamically mapped to a set of permissions by the current Policy whenever a permission is checked.
