   java.security.Permission
      ch.ethz.prose.ProsePermission

ProsePermission
final public class ProsePermission extends Permission implements Serializable(Code)
The class ProsePermission is used for access control of critical parts in the RUNES system. The names recognized and their semantics can be seen in the following list, to specify all names, one can use the wildcard "*".

  • registerListener: guards the creation of breakpoints
  • startupExtensionSystem: if granted, ProseSystem.startup will be performed privileged under the the restrictions of ProseSystem only. This permission should simplify the Java security policy definition, as only ProseSystem needs several fine grained permissions, and all classes that need to start runes can do with the ProsePermission "startupExtensionSystem"

So an entry in the standard policy file allowing all classes to install extensions would look like:

 grant {
 ch.ethz.prose.ProsePermission "registerListener";
 }

Constructor Summary
public  ProsePermission(String name)
     Constructs a runes permission with the specified name.
public  ProsePermission(String name, String actions)
     Constructs a runes permission with the specified name and action.

Method Summary
public  booleanequals(Object obj)
    
public  StringgetActions()
     Returns an empty string as this class does not use actions.
public  inthashCode()
    
public  booleanimplies(Permission p)
     Checks whether this permission implies permission p (if names are equal or at least this permission was created with the wildcard as parameter) or not.


Constructor Detail
ProsePermission
public ProsePermission(String name)(Code)
Constructs a runes permission with the specified name.
Parameters:
  name - the name of the permission or * for all names.



ProsePermission
public ProsePermission(String name, String actions)(Code)
Constructs a runes permission with the specified name and action. This constructor seems to be necessary to the standard policy file implementation though this class completely ignores the action parameter.
Parameters:
  name - the name of the permission or * for all names.
Parameters:
  actions - ignored!!!




Method Detail
equals
public boolean equals(Object obj)(Code)



getActions
public String getActions()(Code)
Returns an empty string as this class does not use actions.



hashCode
public int hashCode()(Code)



implies
public boolean implies(Permission p)(Code)
Checks whether this permission implies permission p (if names are equal or at least this permission was created with the wildcard as parameter) or not.
Parameters:
  p - the permission to be compared to
