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<RequestValue> 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<RequestValue> 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.

Note: The content parameter value overrides the accept media type!
