Deprecated.

As of 8.0, a lightweight lambda-based converter can be build with Binder.forField(...).withConverter(...) methods.

A converter that converts from String to Collection of tokens and back.

Allows to break a string into tokens using delimiter. Each token can be converted to its own model using provided converter.

Default constructor uses ", " as delimiter string and String for token types. Other constructors allow to configure delimiter and token types.

public StringToCollectionConverter()

Deprecated.

Creates converter with ", " as delimiter and String as token model type in collection.

StringToCollectionConverter

public StringToCollectionConverter(String delimiter)

Deprecated.

Parameters:

delimiter - custom delimiter

StringToCollectionConverter

public StringToCollectionConverter(Converter<String,?> tokenConverter,
                                   Class<?> tokenType)

Deprecated.

Creates converter with given tokenConverter for convert tokens and expected tokenType.

If tokenConverter is null then no conversation is done and String is used as token type in resulting model collection.

Parameters:

tokenConverter - converter for token

tokenType - expected token model type

StringToCollectionConverter

public StringToCollectionConverter(String delimiter,
                                   Converter<String,?> tokenConverter,
                                   Class<?> tokenClass)

Deprecated.

Creates converter with given tokenConverter for convert tokens and expected tokenType.

If tokenConverter is null then no conversation is done and String is used as token type in resulting model collection.

Parameters:

tokenConverter - converter for token

tokenClass - expected token model type

delimiter - delimiter in presentation string

StringToCollectionConverter

public StringToCollectionConverter(String delimiter,
                                   Converter<String,?> tokenConverter,
                                   Class<?> tokenClass,
                                   StringToCollectionConverter.CollectionFactory factory)

Deprecated.

Creates converter with given tokenConverter for convert tokens and expected tokenType.

If tokenConverter is null then no conversation is done and String is used as token type in resulting model collection.

Parameters:

tokenConverter - converter for token

tokenClass - expected token model type

delimiter - delimiter in presentation string

factory - factory to create resulting collection

Method Detail

getModelType

public Class<Collection> getModelType()

Deprecated.

Description copied from interface: Converter

The source type of the converter. Values of this type can be passed to Converter.convertToPresentation(Object, Class, Locale).

Specified by:

getModelType in interface Converter<String,Collection>

Returns:

The source type

getPresentationType

public Class<String> getPresentationType()

Deprecated.

Description copied from interface: Converter

The target type of the converter. Values of this type can be passed to Converter.convertToModel(Object, Class, Locale).

Specified by:

getPresentationType in interface Converter<String,Collection>

Returns:

The target type

convertToModel

public Collection convertToModel(String value,
                                 Class<? extends Collection> targetType,
                                 Locale locale)
                          throws Converter.ConversionException

Deprecated.

Description copied from interface: Converter

Converts the given value from target type to source type.

A converter can optionally use locale to do the conversion.

A converter should in most cases be symmetric so chaining Converter.convertToPresentation(Object, Class, Locale) and Converter.convertToModel(Object, Class, Locale) should return the original value.

Specified by:

convertToModel in interface Converter<String,Collection>

Parameters:

value - The value to convert, compatible with the target type. Can be null

targetType - The requested type of the return value

locale - The locale to use for conversion. Can be null.

Returns:

The converted value compatible with the source type

Throws:

Converter.ConversionException - If the value could not be converted

convertToPresentation

public String convertToPresentation(Collection value,
                                    Class<? extends String> targetType,
                                    Locale locale)
                             throws Converter.ConversionException

Deprecated.
