| Arguments.java | Class | A "name=value" parser.
Note that Arguments instances are unmodifiable, like Strings.
Example use:
Arguments args = new Arguments("x=y, q=one, q=two, z=99");
String x = args.getString("x");
assert "y".equals(x);
int z = args.getInt("z", 1234);
assert z == 99;
List<String> q = args.getStrings("q");
assert q != null && q.size() == 2;
The Cougaar component model includes built-in support to invoke an optional
"setArguments" method. |

in time and ends before a known point in time.

negative 1 millisecond duration. |
