      • setProtectionDomain

        public static void setProtectionDomain​(java.security.ProtectionDomain protectionDomain)
        Sets the protection to be used for classes loaded via the loadClassFromBytes method. By default, the protection domain of this class is used for the loaded classes.
        Parameters:
        protectionDomain - the protection domain to be used
        See Also:
        loadClassFromBytes(String, byte[])

      • setProtectionDomainFactory

        public static void setProtectionDomainFactory​(ProtectionDomainFactory protectionDomainFactory)
        Sets a protection domain factory to be used for creating protection domains for the classes loaded by instances of this class.

        For every instance of this class, getProtectionDomain is called and the resulting protection domain is used when loading classes through the newly created classloader.

        Parameters:
        protectionDomainFactory - the protection domain factory.
        See Also:
        ProtectionDomainFactory.getProtectionDomain(ClassLoader)
