Interface ResourceMapper

All Known Implementing Classes:
ResourceMapperImpl
@ProviderType public interface ResourceMapper
Allows access to resource mappings

This interface superceeds the resource mapping functionality present in the ResourceResolver. Although the methods present in that interface will continue to work, the resource mapper will provide better APIs to access the resource mappings.

Implementations of this class are obtained by adapting a ResourceResolver instance. As such, the mappings returned by its methods reflect the repository permissions of the underyling resolver instance.

  • Method Details

    • getMapping

      @NotNull @NotNull String getMapping(@NotNull @NotNull String resourcePath)
      Returns a path mapped from the (resource) path applying the reverse mapping used by the ResourceResolver.resolve(String) such that when the path is given to the ResourceResolver.resolve(String) method the same resource is returned.

      Note, that technically the resourcePath need not refer to an existing resource. This method just applies the mappings and returns the resulting string. If the resourcePath does not address an existing resource roundtripping may of course not work and calling ResourceResolver.resolve(String) with the path returned may return null.

      This method is intended as the reverse operation of the ResourceResolver.resolve(String) method.

      Parameters:
      resourcePath - The path for which to return a mapped path.
      Returns:
      The mapped path.
      Throws:
      IllegalStateException - if the underlying resource resolver has already been closed.
      Since:
      1.0.0 (Sling API Bundle 2.19.0)

    • getMapping

      @NotNull @NotNull String getMapping(@NotNull @NotNull String resourcePath, @NotNull @NotNull javax.servlet.http.HttpServletRequest request)
      Returns an URL mapped from the (resource) path applying the reverse mapping used by the ResourceResolver.resolve(HttpServletRequest, String) such that when the path is given to the ResourceResolver.resolve(HttpServletRequest, String) method the same resource is returned.

      Note, that technically the resourcePath need not refer to an existing resource. This method just applies the mappings and returns the resulting string. If the resourcePath does not address an existing resource roundtripping may of course not work and calling ResourceResolver.resolve(HttpServletRequest, String) with the path returned may return null.

      This method is intended as the reverse operation of the ResourceResolver.resolve(HttpServletRequest, String) method. As such the URL returned is expected to be an absolute URL including scheme, host, any servlet context path and the actual path used to resolve the resource.

      Parameters:
      resourcePath - The path for which to return a mapped path.
      request - The http servlet request object which may be used to apply more mapping functionality.
      Returns:
      The mapped URL.
      Throws:
      IllegalStateException - if the underlying resource resolver has already been closed.
      Since:
      1.0.0 (Sling API Bundle 2.19.0)

    • getAllMappings

      Collection<String> getAllMappings(@NotNull @NotNull String resourcePath)
      Returns all possible mappings for a given resourcePath as paths.

      This method differs from the getMapping(String) variant by guaranteeing that all possible mappings are returned for a specified path.

      The mappings are not returned in any particular order.

      Parameters:
      resourcePath - The path for which to return a mapped path.
      Returns:
      a collection of mapped URLs, in no particular order. May not be null or empty.
      Throws:
      IllegalStateException - if the underlying resource resolver has already been closed.
      Since:
      1.0.0 (Sling API Bundle 2.19.0)

    • getAllMappings

      Collection<String> getAllMappings(@NotNull @NotNull String resourcePath, @NotNull @NotNull javax.servlet.http.HttpServletRequest request)
      Returns all possible mappings for a given resourcePath as URLs.

      This method differs from the getMapping(String, HttpServletRequest) variant by guaranteeing that all possible mappings are returned for a specified path.

      The mappings are not returned in any particular order.

      Parameters:
      resourcePath - The path for which to return a mapped path.
      request - The http servlet request object which may be used to apply more mapping functionality.
      Returns:
      a collection of mapped URLs, in no particular order. May not be null or empty.
      Throws:
      IllegalStateException - if the underlying resource resolver has already been closed.
      Since:
