Method Detail

isInstantiationAuthorized

public boolean isInstantiationAuthorized(java.lang.Class componentClass)

Description copied from interface: IAuthorizationStrategy

Checks whether an instance of the given component class may be created. If this method returns false, the IUnauthorizedComponentInstantiationListener that is configured in the security settings will be called. The default implementation of that listener throws a UnauthorizedInstantiationException.

If you wish to implement a strategy that authenticates users which cannot access a given Page (or other Component), you can simply throw a RestartResponseAtInterceptPageException in your implementation of this method.

Parameters:

componentClass - The component class to check

Returns:

Whether the given component may be created

isActionAuthorized

public boolean isActionAuthorized(Component component,
                                  Action action)

Description copied from interface: IAuthorizationStrategy

Gets whether the given action is permitted. If it is, this method should return true. If it isn't, this method should either return false or - in case of a serious breach - throw a security exception. Returning is generally preferable over throwing an exception as that doesn't break the normal flow.

Parameters:

component - The component to be acted upon

action - The action to authorize on the component

Returns:

Whether the given action may be taken on the given component
