public class FieldVerifier extends Object
FieldVerifier validates that the name the user enters is valid.
This class is in the shared
packing because we use it in both
the client code and on the server. On the client, we verify that the name is
valid before sending an RPC request so the user doesn't have to wait for a
network round trip to get feedback. On the server, we verify that the name is
correct to ensure that the input is correct regardless of where the RPC
originates.
When creating a class that is used on both the client and the server, be sure that all code is translatable and does not use native JavaScript. Code that is note translatable (such as code that interacts with a database or the file system) cannot be compiled into client side JavaScript. Code that uses native JavaScript (such as Widgets) cannot be run on the server.
