* - verifying credentials of incoming messages.
|
|
* - testing whether or not the sender is allowed to access the requested resource by testing the

|
* request to a set of rules.
|
|
* - allowing the shell to respond to a remote request that doesn't match any of the rules that
|
|
* are in effect.
|
|
* Besides internal use in libplasma, the only moment you'll need to access this class is when you
|
|
* implement a plasma shell.
