Method Detail

parseLocations

public static ParamLocationRecognizer parseLocations(java.lang.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 java.util.Map<java.lang.String,ParamLocationRecognizer.NamedParameterDescription> 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 java.util.List<java.lang.Integer> getOrdinalParameterLocationList()

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

Returns:

The list of ordinal parameter locations.

ordinalParameter

public void ordinalParameter(int position)

Description copied from interface: ParameterParser.Recognizer

Called when an ordinal parameter is recognized

Specified by:

ordinalParameter in interface ParameterParser.Recognizer

Parameters:

position - The position within the query

namedParameter

public void namedParameter(java.lang.String name,
                           int position)

Description copied from interface: ParameterParser.Recognizer

Called when a named parameter is recognized

Specified by:

namedParameter in interface ParameterParser.Recognizer

Parameters:

name - The recognized parameter name

position - The position within the query

jpaPositionalParameter

public void jpaPositionalParameter(java.lang.String name,
                                   int position)

Description copied from interface: ParameterParser.Recognizer

Called when a JPA-style named parameter is recognized

Specified by:

jpaPositionalParameter in interface ParameterParser.Recognizer

Parameters:

name - The name of the JPA-style parameter

position - The position within the query

other

public void other(char character)

Description copied from interface: ParameterParser.Recognizer

Called when a character that is not a parameter (or part of a parameter dfinition) is recognized.

Specified by:

other in interface ParameterParser.Recognizer

Parameters:

character - The recognized character

outParameter

public void outParameter(int position)

Description copied from interface: ParameterParser.Recognizer

Called when an output parameter is recognized

Specified by:

outParameter in interface ParameterParser.Recognizer

Parameters:

position - The position within the query
