Class EnumArgumentType<T extends Enum<T>>

java.lang.Object

net.sourceforge.argparse4j.impl.type.EnumArgumentType<T>

Type Parameters:

T - Type of enum

All Implemented Interfaces:

ArgumentType<T>

Deprecated.

Use ReflectArgumentType instead.

@Deprecated
public class EnumArgumentType<T extends Enum<T>>
extends Object
implements ArgumentType<T>

ArgumentType subclass for enum type.

Since enum does not have a constructor with string argument, it cannot be used with Argument.type(Class). Instead use this class to specify enum type. The enums in its nature have limited number of members. In convert(ArgumentParser, Argument, String), String value will be converted to one of them. If it cannot be converted, convert(ArgumentParser, Argument, String) will throw ArgumentParserException. This means it already act like a Argument.choices(Object...).
