 List<String> args,
 @Nonnull
 List<String> allAllowedFields,
 @Nonnull
 List<String> allAllowedHeaders)

In several situations (mostly SQL class UDFs) we see the same need: A sequence of strings must be analyzed and converted into parameters for the UserAgentAnalyzer. Supported format patterns this parser will detect: - useragent - useragent [ headername, headervalue ]+ - [ headername, headervalue ]+ Notes: - The useragent and any of the headervalues can be null or empty. - A trailing list of null values will be ignored - When not having the useragent as the first value the Analyzers will expect a "User-Agent" header in the list.

Parameters:

args - The list of arguments passed from the user

allAllowedFields - The list of all supported fieldnames (i.e. all possible outputs)

allAllowedHeaders - The list of all supported headers (i.e. all supported inputs)

Returns:

The list of request headers and the list of wanted fields. It is up to the calling system to choose which to use.
