Package org.infinispan.security

Class Security

  • public final class Security
extends java.lang.Object
    Security. A simple class to implement caller privileges without a security manager and a much faster implementations of the Subject.doAs(Subject, PrivilegedAction) and Subject.doAs(Subject, PrivilegedExceptionAction) when interaction with the AccessControlContext is not needed. N.B. this uses the caller's Package, this can easily be subverted by placing the calling code within the org.infinispan hierarchy. However for most purposes this is ok.
