Exempel

Följande kod visar användningen av Resolve metoden. Det här kodexemplet är en del av ett större exempel för PolicyLevel klassen.

// Demonstrate the use of ResolvePolicy for the supplied evidence and a specified policy level.

   while ( codeGroup->MoveNext() )

   }

   // Show how Resolve is used to determine the set of permissions that 
   // the security system grants to code, based on the evidence.
   // Show the granted permissions.

Resolve är den grundläggande principutvärderingsåtgärden för principnivåer. Med tanke på en uppsättning bevis som indata testar den här metoden medlemskapsvillkor för kodgrupper som börjar vid roten och arbetar nedåt enligt matchning. Kombinationen av behörigheter som följer av matchande kodgrupper genererar en PolicyStatement som returneras.

Vid beviljande av behörigheter till kod använder säkerhetsprincipen de lösta principinstruktionerna för alla tillämpliga principnivåer, tillsammans med kodbegäran för behörigheter.
