Method Detail

isInstantiationAuthorized

public <T extends IRequestableComponent> boolean isInstantiationAuthorized(Class<T> 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.

Specified by:

isInstantiationAuthorized in interface IAuthorizationStrategy

Overrides:

isInstantiationAuthorized in class IAuthorizationStrategy.AllowAllAuthorizationStrategy

Parameters:

componentClass - The component class to check

Returns:

Whether the given component may be created

See Also:

IAuthorizationStrategy.isInstantiationAuthorized(java.lang.Class)

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.

Specified by:

isActionAuthorized in interface IAuthorizationStrategy

Overrides:

isActionAuthorized in class IAuthorizationStrategy.AllowAllAuthorizationStrategy

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

See Also:

IAuthorizationStrategy.isActionAuthorized(org.apache.wicket.Component, org.apache.wicket.authorization.Action)

isActionAuthorized

protected boolean isActionAuthorized(Class<?> componentClass,
                                     Action action)

isResourceAuthorized

public boolean isResourceAuthorized(IResource resource,
                                    PageParameters pageParameters)

Description copied from interface: IAuthorizationStrategy

Checks whether a request with some parameters is allowed to a resource.

Specified by:

isResourceAuthorized in interface IAuthorizationStrategy

Overrides:

isResourceAuthorized in class IAuthorizationStrategy.AllowAllAuthorizationStrategy

Parameters:

resource - The resource that should be processed

pageParameters - The request parameters

Returns:

true if the request to this resource is allowed.
