Constructor Details

SubjectDomainCombiner

public SubjectDomainCombiner(Subject subject)

Deprecated, for removal: This API element is subject to removal in a future version.

Associate the provided Subject with this SubjectDomainCombiner.

Parameters:: subject - the Subject to be associated with this SubjectDomainCombiner.

Method Details

getSubject

public Subject getSubject()

Deprecated, for removal: This API element is subject to removal in a future version.

Get the Subject associated with this SubjectDomainCombiner.

Returns:: the Subject associated with this SubjectDomainCombiner, or null if no Subject is associated with this SubjectDomainCombiner.

combine

public ProtectionDomain[] combine(ProtectionDomain[] currentDomains, ProtectionDomain[] assignedDomains)

Deprecated, for removal: This API element is subject to removal in a future version.

Update the relevant ProtectionDomains with the Principals from the 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.

Specified by:: combine in interface DomainCombiner
Parameters:: currentDomains - the ProtectionDomains associated with the current execution Thread. The ProtectionDomains are listed in order of execution, with the most recently executing ProtectionDomain residing at the beginning of the array. This parameter may be null if the current execution Thread has no associated ProtectionDomains.; assignedDomains - the inherited ProtectionDomains. This parameter may be null if there were no inherited ProtectionDomains.
Returns:: a new array consisting of the updated ProtectionDomains, or null.
