public class ConverterSet
extends ConverterBase

Class to handle converting of types from one to another. Other Converters can be registered with this ConverterSet and it will try them all in turn until it finds one that works. This class also provides a set of "standard" converters that handle the primitive types, that can be installed by calling registerPrimitiveConverters().

doConvert

protected java.lang.Object doConvert(java.lang.Object toConvert,
                                     java.lang.Class convertTo,
                                     Converter context,
                                     boolean safe)
Description copied from class: ConverterBase
Convert an Object to another type.
Overrides:
doConvert in class ConverterBase
Tags copied from class: ConverterBase
Parameters:
toConvert - Value to convert
convertTo - Type to convert to
context - The context within which the converter was called. If Converters use other Converters, this is passed as the outermost Converter so that recursive calls have access to all available Converters. Converter implementations should pass this if passed null.
safe - If false, errors should be returned.
Returns:
null if this converter doesn't handle this type to convertTo, or a ConvertFail exception if there was an error and safe is false.

register

public void register(Converter converter)

registerPrimitiveConverters

public void registerPrimitiveConverters()
register the standard converters for the primitive types
