new(classname,signature,arg...) |
Invokes a constructor on the specified class
by introspection. The signature string specifies the argument types
of the method as a comma separated list of (fully qualified) type
names. The arguments must be cast accordingly. |
The specification @|new("java.util.Date","long", long(1293840000000)) . This use corresponds
