Class EnumConverter

java.lang.Object
  org.spicefactory.lib.reflect.convert.EnumConverter

All Implemented Interfaces:

Converter<Enum<?>>

public class EnumConverter
extends Object
implements Converter<Enum<?>>

Converter implementation for converting Enum types. It can handle String values which will be interpreted as the name of the Enum and Number values which will be interpreted as the ordinal of the Enum. For values that are already instances of Enum it will only check if the type matches the required target type and return the value unchanged.

Method Detail

convert

public Enum<? extends Enum<?>> convert(Object value,
                                       TypeContext typeContext)
                                throws ConversionException

Description copied from interface: Converter

Converts the given value to the target type of this converter. The TypeContext parameter serves as an additional hint for the required type of the converted value. Example: If a Converter implementation handles all kinds of Collections (implements Converter<Collection>) the given TypeContext might provide information for the exact nature of the Collection (like List<String>).

Specified by:

convert in interface Converter<Enum<?>>

Parameters:

value - the value to be converted

typeContext - additional information for the required type of the converted value

Returns:

the converted value

Throws:

ConversionException - if the conversion fails

supports

public boolean supports(Class<?> type)

Description copied from interface: Converter

Checks if this converter can convert instances of the given class to the target type of this converter. Of course this does not give any guarantee that conversion will succeed for any instance of the given type.

Specified by:

supports in interface Converter<Enum<?>>

Parameters:

type - the class to be checked

Returns:

true if this converter can convert instances of the given class
