All Implemented Interfaces:

Converter<T>

public abstract class BoolOrEnumConverter<T extends java.lang.Enum<T>>
extends EnumConverter<T>

Converter that can also convert from booleans and enumerations.

This is able to additionally convert from the standard set of boolean string values. If there is an overlap in values, those from the underlying enumeration will be taken.

                              T trueValue,
                              T falseValue)

Parameters:

enumType - The type of your enumeration; usually a class literal like MyEnum.class

typeName - The intuitive name of your enumeration, for example, the type name for CompilationMode might be "compilation mode".

trueValue - The enumeration value to associate with true.

falseValue - The enumeration value to associate with false.
