Methods in org.springframework.web.portlet that return HandlerInterceptor
`HandlerInterceptor[]` `HandlerExecutionChain.getInterceptors()` Return the array of interceptors to apply (in the given order).

Methods in org.springframework.web.portlet with parameters of type HandlerInterceptor
`void` `HandlerExecutionChain.addInterceptor(HandlerInterceptor interceptor)`
`void` `HandlerExecutionChain.addInterceptors(HandlerInterceptor[] interceptors)`

Constructors in org.springframework.web.portlet with parameters of type HandlerInterceptor
`HandlerExecutionChain(Object handler, HandlerInterceptor[] interceptors)` Create a new HandlerExecutionChain.

Uses of HandlerInterceptor in org.springframework.web.portlet.handler

Classes in org.springframework.web.portlet.handler that implement HandlerInterceptor
`class` `HandlerInterceptorAdapter` Abstract adapter class for the HandlerInterceptor interface, for simplified implementation of pre-only/post-only interceptors.
`class` `ParameterMappingInterceptor` Interceptor to forward a request parameter from the `ActionRequest` to the `RenderRequest`.
`class` `UserRoleAuthorizationInterceptor` Interceptor that checks the authorization of the current user via the user's roles, as evaluated by PortletRequest's isUserInRole method.
`class` `WebRequestHandlerInterceptorAdapter` Adapter that implements the Portlet HandlerInterceptor interface and wraps an underlying WebRequestInterceptor.

Methods in org.springframework.web.portlet.handler that return HandlerInterceptor
`protected HandlerInterceptor` `AbstractHandlerMapping.adaptInterceptor(Object interceptor)` Adapt the given interceptor object to the HandlerInterceptor interface.
`protected HandlerInterceptor[]` `AbstractHandlerMapping.getAdaptedInterceptors()` Return the adapted interceptors as HandlerInterceptor array.
