Method Details

getConverterFactories

public static Set<ConverterFactory> getConverterFactories(Hints hints)

Returns a set of all available implementations for the ConverterFactory interface.

Parameters:

hints - An optional map of hints, or null if none.

Returns:

Set of available ConverterFactory implementations.

getConverterFactories

public static Set<ConverterFactory> getConverterFactories(Class<?> source,
 Class<?> target)

Returns a set of all available ConverterFactory's which can handle convert from the source to destination class.

This method essentially returns all factories in which the following returns non null.

 factory.createConverter( source, target );

convert

public static <T> T convert(Object source,
 Class<T> target)

Converts an object of a particular type into an object of a different type.

Convenience for convert(Object, Class, Hints)

Parameters:

source - The object to convert.

target - The type of the converted value.

Returns:

The converted value as an instance of target, or null if a converter could not be found

convert

public static <T> T convert(Object source,
 Class<T> target,
 Hints hints)

Converts an object of a particular type into an object of a different type.

This method uses the ConverterFactory extension point to find a converter capable of performing the conversion. The first converter found is the one used. Using this class there is no way to guarantee which converter will be used.

Parameters:

source - The object to convert.

target - The type of the converted value.

hints - Any hints for the converter factory.

Returns:

The converted value as an instance of target, or null if a converter could not be found.
