Hi Jochen,
I assume there is a typo ("?:" -> "?=") in your example, but apart from
that, Groovy-truth prohibits your solution for any method returning a
type which has special Groovy-truth meaning, so what we would need for
general applicability and terseness would be:
def chooseMethod(String methodName, Object[] arguments) {
def methodChosen = doChooseMethod(methodName, arguments)
methodChosen ??= doChooseMethod(methodName,
adjustArguments(arguments.clone(), Character.TYPE))
methodChosen ??= doChooseMethod(methodName,
adjustArguments(arguments.clone(), Integer.TYPE))
return methodChosen ??: throw new
GroovyRuntimeException("$methodName not found")
}
oh dear, looks like it was to early in the morning;
I did mean this:
def chooseMethod(String methodName, Object[] arguments) {
def methodChosen = doChooseMethod(methodName, arguments)
methodChosen = methodChosen ?: doChooseMethod(methodName,
adjustArguments(arguments.clone(), Character.TYPE))
methodChosen = methodChosen ?: doChooseMethod(methodName,
adjustArguments(arguments.clone(), Integer.TYPE))
if (null != methodChosen) return methodChosen
throw new GroovyRuntimeException("$methodName not found")
}
bye Jochen
