Method Detail

convertToStandardInternetMediaType

public static String convertToStandardInternetMediaType(String mediaType)

Converts short form of media type to the proper internet standard, e.g. json to application/json.

getResIds

public static List<NameValuePair> getResIds(SqlResource sqlResource,
                            String[] values)

Returns name-value pairs, resourceId and value, for given resource and ordered value array.

getRequestMediaType

public static String getRequestMediaType(String contentMediaType)

Returns best match for Content-Type header or the original media type if it doesn't match.

getResponseMediaType

public static String getResponseMediaType(List<NameValuePair> params,
                          String requestMediaType,
                          String acceptMediaType)

Determines content type from parameters, and removing the output param if present. If it is not present then uses the accept media type. The accept media type can be single mime-type or an Accept header string with multiple mime-types, some possibly with quality factors. If the accept media type is not present, uses the request media type, or if it is null or form url encoded, then returns the default media type, HttpRequestAttributes.DEFAULT_MEDIA_TYPE. Note: The content parameter value overrides the accept media type!
