 * The purpose of generated class in src/main/java for Union types is to create new instances of unions from a string
 * representation. In some cases it is very difficult to automate it since there can be unions such as (uint32 -
 * uint16), or (string - uint32).
 * <p/>
 * The reason behind putting it under src/main/java is: This class is generated in form of a stub and needs to be
 * finished by the user. This class is generated only once to prevent loss of user code.
