Is there any way to require that a class have a default (no parameter) constructor, aside from using a reflection check like the following? (the following would work, but it's hacky and reflection is slow)
boolean valid = false;
for(Constructor<?> c : TParse.class.getConstructors())
{
if(c.getParameterTypes().length == 0) {
valid = true;
break;
}
}
if(!valid)
throw new MissingDefaultConstructorException(...);
