public SubjectDomainCombiner(Subject subject)
Subject with this SubjectDomainCombiner.subject - the Subject to be associated with this SubjectDomainCombiner.public Subject getSubject()
Subject associated with this SubjectDomainCombiner.Subject associated with this SubjectDomainCombiner, or null if no Subject is associated with this SubjectDomainCombiner.SecurityException - if the caller does not have permission to get the Subject associated with this SubjectDomainCombiner.public ProtectionDomain[] combine(ProtectionDomain[] currentDomains, ProtectionDomain[] assignedDomains)
Subject associated with this SubjectDomainCombiner. A new ProtectionDomain instance is created for each non-static ProtectionDomain ( (staticPermissionsOnly() == false) in the currentDomains array. Each new ProtectionDomain instance is created using the CodeSource, Permissions and ClassLoader from the corresponding ProtectionDomain in currentDomains, as well as with the Principals from the Subject associated with this SubjectDomainCombiner. Static ProtectionDomains are combined as-is and no new instance is created.
All of the ProtectionDomains (static and newly instantiated) are combined into a new array. The ProtectionDomains from the assignedDomains array are appended to this new array, and the result is returned.
Note that optimizations such as the removal of duplicate ProtectionDomains may have occurred. In addition, caching of ProtectionDomains may be permitted.
