Examples with PreMatching javax.ws.rs.container.PreMatching used on opensource projects

Example 1 with PreMatching

use of javax.ws.rs.container.PreMatching in project jersey by jersey.

the class ApplicationHandler method filterNameBound.

/**
     * Takes collection of all filters/interceptors (either request/reader or response/writer)
     * and separates out all name-bound filters/interceptors, returns them as a separate MultivaluedMap,
     * mapping the name-bound annotation to the list of name-bound filters/interceptors. The same key values
     * are also added into the inverse map passed in {@code inverseNameBoundMap}.
     * <p/>
     * Note, the name-bound filters/interceptors are removed from the original filters/interceptors collection.
     * If non-null collection is passed in the postMatching parameter (applicable for filters only),
     * this method also removes all the global
     * postMatching filters from the original collection and adds them to the collection passed in the postMatching
     * parameter.
     *
     * @param all                     Collection of all filters to be processed.
     * @param preMatchingFilters      Collection into which pre-matching filters should be added.
     * @param componentBag            Component bag
     * @param applicationNameBindings Collection of name binding annotations attached to the JAX-RS application.
     * @param inverseNameBoundMap     Inverse name bound map into which the name bound providers should be inserted. The keys
     *                                are providers (filters, interceptor)
     * @return {@link MultivaluedMap} of all name-bound filters.
