Method Detail

getMetadataETag

public String getMetadataETag()

Description copied from interface: ServiceMetadataETagSupport

Since the Olingo library cannot generate a metadata document etag in a generic way we call this method to retrieve an application specific etag for the metadata document. If this interface is registered applications can return an etag or null here to provide caching support for clients. If a client sends a GET request to the metadata document and this method delivers an etag we will match it to the request. If there has been no modification we will return a 304 NOT MODIFIED status code. If this interface is not registered or delivers null we just send back the usual metadata response.

the application generated etag for the metadata document
