Working with Rejections

Compared with regular Events, Rejections are defined differently. Here is the summary of the differences:

  1. java_multiple_files file option must be set to false

    By doing this we instruct Protobuf Compiler to put all the rejection classes in a single outer class. Spine Model Compiler for Java generates ThrowableMessage classes for all these messages. These classes will be named after the classes of rejection messages. Putting rejection message classes under an outer class avoids name clash inside the package.

  2. Omit java_outer_classname option

    Thus, the outer class name is derived from the name of the file where rejection messages are declared. Usually the outer class names are named using the name with the suffix Proto. We want the name to end with Rejections so that it is clearly visible what is inside this class.
