getConverter

public static <PRESENTATIONTYPE,MODELTYPE> Converter<PRESENTATIONTYPE,MODELTYPE> getConverter(Class<PRESENTATIONTYPE> presentationType,
                                                                                                          Class<MODELTYPE> modelType,

Deprecated.

Finds a converter that can convert from the given presentation type to the given model type and back. Uses the given application to find a ConverterFactory or, if application is null, uses the VaadinSession.getCurrent().

Type Parameters:

PRESENTATIONTYPE - the presentation type

MODELTYPE - the model type

Parameters:

presentationType - the presentation type

modelType - the model type

session - the session to use to find a ConverterFactory or null to use the current session

Returns:

a Converter capable of converting between the given types or null if no converter was found

convertFromModel

public static <PRESENTATIONTYPE,MODELTYPE> PRESENTATIONTYPE convertFromModel(MODELTYPE modelValue,
                                                                                   Class<? extends PRESENTATIONTYPE> presentationType,
                                                                                   Converter<PRESENTATIONTYPE,MODELTYPE> converter,
                                                                                   Locale locale)

Deprecated.

Convert the given value from the data source type to the UI type.

Type Parameters:

PRESENTATIONTYPE - the presentation type

MODELTYPE - the model type

Parameters:

modelValue - the model value to convert

presentationType - the type of the presentation value

converter - the converter to use

locale - the locale to use for conversion

Returns:

the converted value, compatible with the presentation type, or the original value if its type is compatible and no converter is set.

Throws:

Converter.ConversionException - if there was a problem converting the value

convertToModel

public static <MODELTYPE,PRESENTATIONTYPE> MODELTYPE convertToModel(PRESENTATIONTYPE presentationValue,
                                                                          Class<MODELTYPE> modelType,
                                                                          Converter<PRESENTATIONTYPE,MODELTYPE> converter,
                                                                          Locale locale)

MODELTYPE - the model type

Parameters:

presentationValue - the presentation value to convert

modelType - the type of the model

converter - the converter to use

locale - the locale to use for conversion

Returns:

the converted value, compatible with the model type, or the original value if its type is compatible and no converter is set.

Throws:

Converter.ConversionException - if there was a problem converting the value

canConverterHandle

public static boolean canConverterHandle(Converter<?,?> converter,
                                         Class<?> presentationType,
                                         Class<?> modelType)

Deprecated.

Checks if the given converter can handle conversion between the given presentation and model type. Does strict type checking and only returns true if the converter claims it can handle exactly the given types.

Parameters:

converter - The converter to check. If this is null the result is always false.

presentationType - The presentation type

modelType - The model type

Returns:

true if the converter supports conversion between the given presentation and model type, false otherwise

                                                 Class<?> modelType)

Deprecated.

Checks if it possible that the given converter can handle conversion between the given presentation and model type somehow.

Parameters:

converter - The converter to check. If this is null the result is always false.

presentationType - The presentation type

modelType - The model type

Returns:

true if the converter possibly support conversion between the given presentation and model type, false otherwise
