DefaultTypeConverterFactory

public DefaultTypeConverterFactory()

Method Detail

init

public void init(Configuration configuration)

Places all the known convertible types and type converters into an instance level Map.

Specified by:

init in interface ConfigurableComponent

Parameters:

configuration - the Configuration object being used by Stripes

getTypeConverter

public TypeConverter getTypeConverter(Class forType,
                                      Locale locale)
                               throws Exception

Gets the applicable type converter for the class passed in. This is based on the default set of type converters which are stored in a Map on this class. Enums are a special case, whereby if there is no converter in the map, the EnumeratedTypeConverter will be returned.

Specified by:

getTypeConverter in interface TypeConverterFactory

Parameters:

forType - the type/Class that is the target type of the conversion. It is assumed that the input type is String, so to convert a String to a Date object you would supply java.util.Date.class.

locale - the locale of the Strings to be converted with the returned converter

Returns:

an instance of a TypeConverter which will convert Strings to the desired type

Throws:

Exception - if the TypeConverter cannot be instantiated

getInstance

public TypeConverter getInstance(Class<? extends TypeConverter> clazz,
                                 Locale locale)
                          throws Exception

Gets an instance of the TypeConverter class specified.

Specified by:

getInstance in interface TypeConverterFactory

Parameters:

clazz - the TypeConverter type that is desired

locale - the locale of the Strings to be converted with the returned converter

Returns:

an instance of the TypeConverter specified

Throws:

Exception - if there is a problem instantiating the TypeConverter
