A little more verbose (as member of class JDepsTask):
enum Option {
VERBOSE (false, "-v", "--verbose"),
PACKAGE (true, "-p", "--package"),
...;
private boolean hasParam;
private String[] aliases;
private Option (boolean hasParam, String aliases...) {
...;
}
process (String form, String param) {
If (hasParam &&
(param == null || param.length == 0 || param.charAt(0) == '-'))
throw new BadArgs("err.missing.arg", form).showUsage(true);
switch (this) {
case VERBOSE : verbose = Verbose.VERBOSE; break;
case PACKAGE : packageNames.add(param); break;
...
}
}
}
