Method Detail

parseLocations

public static ParamLocationRecognizer parseLocations(String query)

Convenience method for creating a param location recognizer and initiating the parse.

Parameters:: query - The query to be parsed for parameter locations.
Returns:: The generated recognizer, with journaled location info.

getNamedParameterDescriptionMap

public Map getNamedParameterDescriptionMap()

Returns the map of named parameter locations. The map is keyed by parameter name; the corresponding value is a (@link NamedParameterDescription}.

Returns:: The map of named parameter locations.

getOrdinalParameterLocationList

public List getOrdinalParameterLocationList()

Returns the list of ordinal parameter locations. The list elements are Integers, representing the location for that given ordinal. Thus getOrdinalParameterLocationList().elementAt(n) represents the location for the nth parameter.

Returns:: The list of ordinal parameter locations.
