Yes, exactly. In code, if you're using the enum-based technique:
switch (message.getType()) {
case FOO:
// use message.getFoo(), break
case BAR:
// use message.getBar(), break
case BAZ:
// use message.getBaz(), break
}
or if you're just using a set of optional fields:
if (message.hasFoo()) {
// use message.getFoo()
} else if (message.hasBar()) {
// use message.getBar()
} else if (message.hasBaz()) {
// use message.getBaz()
}
