Annotation Type GwtTransient

@Documented
@Retention(value=RUNTIME)
@Target(value=FIELD)
public @interface GwtTransient

This annotation means the same thing as the transient keyword, but it is ignored by all serialization systems other than GWT's. Usually the transient keyword should be used in preference to this annotation. However, for types used with multiple serialization systems, it can be useful.
