Method Details
-
getRegistry
Gets the option handler registry singleton instance.- Returns:
- a shared instance of the registry.
-
registerHandler
Registers a user-definedOptionHandler
class with args4j.This method allows users to extend the behavior of args4j by writing their own

implementation.- Parameters:
valueType
- The specified handler is used when the field/method annotated byOption
is of this type.handlerClass
- This class must have the constructor that has the same signature asOptionHandler(CmdLineParser, OptionDef, Setter)
- Throws:
NullPointerException
- ifvalueType
orhandlerClass
isnull
.IllegalArgumentException
- ifhandlerClass
is not a subtype ofOptionHandler
