  • combine

  Update the relevant ProtectionDomains with the Principals from the Subject associated with thisSubjectDomainCombiner.
  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 incurrentDomains, as well as with the Principals from the Subject associated with thisSubjectDomainCombiner. 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 theassignedDomains 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](../../../java/security/DomainCombiner.html#combine%28java.security.ProtectionDomain%5B%5D,java.security.ProtectionDomain%5B%5D%29) in interface [DomainCombiner](../../../java/security/DomainCombiner.html "interface in java.security")
  Parameters:
  currentDomains - the ProtectionDomains associated with the current execution Thread, up to the most recent privileged ProtectionDomain. 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 ProtectionDomains inherited from the parent Thread, or the ProtectionDomains from the privileged context, if a call toAccessController.doPrivileged(..., context) had occurred This parameter may be null if there were no ProtectionDomains inherited from the parent Thread, or from the privileged context.
  Returns:
  a new array consisting of the updated ProtectionDomains, or null.
