Modifier and Type	Method and Description
String	getTypeToken() Returns the string which serves as a value type token for parameters of this type.
Constraints	parse(Properties db, TokenTranslator tr, ParserLoader parserLoader) Returns an object describing particular constraints as defined in the specified property database.
Serializable	parseItem(String token, Constraints constraints, Parameters soFar) Returns the parsed object corresponding to the given list item, which in this case is a Number instance represented by the token.

Constructor Detail

NumberListParameterParser

public NumberListParameterParser()

Default constructor.

NumberListParameterParser

public NumberListParameterParser(Locale locale)

Constructs a new string parameter parser using the given locale.

Parameters:

locale - Locale to associate with this parser.

Method Detail

getTypeToken

public String getTypeToken()

Description copied from interface: TypedParser

Returns the string which serves as a value type token for parameters of this type.

Returns:

type token string of the parser

TypedParser.getTypeToken()

parse

public Constraints parse(Properties db,
                TokenTranslator tr,
                ParserLoader parserLoader)

Returns an object describing particular constraints as defined in the specified property database.

Parameters:

db - Set of properties that can be used to parametrize the constraints implementation.

tr - A token translator that can be used for locale-specific or other types of value translation.

parserLoader - Reference to the parameter and constraints parser loader.

Returns:

NumberListConstraints instance created using the specified properties.

parseItem

public Serializable parseItem(String token,
                     Constraints constraints,
                     Parameters soFar)

Returns the parsed object corresponding to the given list item, which in this case is a Number instance represented by the token.

Specified by:

parseItem in class ListParameterParser

Parameters:

token - String to be decoded/parsed into a Serializable entity.

constraints - Constraints & hints to use for parsing and for validating the resulting Serializable.

soFar - Parameters accumulated by the parsing process thus far.

Returns:

The specified token instance.
