AccessControlContext | java.security |
This class encapsulates the
state of a call stack. The checkPermission( )
method can make access-control decisions based on the saved state of
the call stack. Access-control checks are usually performed by the
AccessController.checkPermission( ) method, which
checks that the current call stack has the required permissions.
Sometimes, however, it is necessary to make access-control decisions
based on a previous state of the call stack. Call
AccessController.getContext( ) to create an
AccessControlContext for a particular call stack.
In Java 1.3, this class has constructors that specify a custom
context in the form of an array of
ProtectionDomain objects and that associate a
DomainCombiner object with an existing
AccessControlContext. This class is used only by
system-level code; typical applications rarely need to use it.
public final class AccessControlContext {
// Public Constructors
public AccessControlContext(ProtectionDomain[ ] context);
1.3 public AccessControlContext(AccessControlContext acc, DomainCombiner
combiner);
// Public Instance Methods
public void checkPermission(Permission perm) throws AccessControlException;
1.3 public DomainCombiner getDomainCombiner( );
// Public Methods Overriding Object
