Method Detail

getResourceFromSearchPath

public static org.apache.sling.api.resource.Resource getResourceFromSearchPath(org.apache.sling.api.resource.Resource base,
                                                                               String path)

Resolves a resource from the search path relative to the base resource by traversing the sling:resourceSuperType chain.

Since this method will traverse the sling:resourceSuperType chain, the ResourceResolver used for resolving the base resource should be able to read the super type resources.

Parameters:

base - the base resource from which to start the lookup

path - the relative path to the resource; if the path is absolute the Resource identified by this path will be returned

Returns:

the resource identified by the relative path or null if no resource was found

Throws:

UnsupportedOperationException - if the resource is not in the resource resolver's search path

IllegalStateException - if the number of steps necessary to search for the resource on the resource superType chain has reached the maximum limit

ResourceResolver.getSearchPath()

getResourceForRequest

public static org.apache.sling.api.resource.Resource getResourceForRequest(org.apache.sling.api.resource.ResourceResolver resolver,
                                                                           org.apache.sling.api.SlingHttpServletRequest request)

Resolves the resource accessed by a request. Since the request can use an anonymous ResourceResolver, the passed resolver parameter should have read access rights to resources from the search path.

Parameters:

resolver - a ResourceResolver that has read access rights to resources from the search path

request - the request

Returns:

the resource identified by the request or null if no resource was found
