AccessController

Class AccessController

public final class AccessController
extends Object

The AccessController class is used for access control operations and decisions.

More specifically, the AccessController class is used for three purposes:

to decide whether an access to a critical system resource is to be allowed or denied, based on the security policy currently in effect,
to mark code as being "privileged", thus affecting subsequent access determinations, and
to obtain a "snapshot" of the current calling context so access-control decisions from a different context can be made with respect to the saved context.
