Interface SubjectSource

All Known Implementing Classes:

WSSubjectSourceImpl

public interface SubjectSource

This plugin can be used to get a Subject which represents an ObjectGrid client. The Subject will then be used for ObjectGrid authorization. The getSubject() method is called by the ObjectGrid runtime when the ObjectGrid.getSession() method is used to get a Session and ObjectGrid security is enabled.

This plug-in is useful for an already authenticated client: it can retrieve the authenticated Subject object and then pass it to the ObjectGrid runtime. Therefore, there is no need for another authentication.

For example, users can use

 Subject.getSubject(AccessControlContext)
 

to get the subject associated with the AccessControlContext and return it in the getSubject() implementation.
