Custom fields on java enum not getting serialized

Question

I have a Java Enum as shown below:

public enum ExecutionMode {
  TYPE_A,
  TYPE_B,
  TYPE_C;

  private ExecutionMode(){} //no args constr- no really require         


        

Answer 1

If the values are constant, this is better and you don't need to serialize anything

public enum ExecutionMode {
  TYPE_A(x,t),
  TYPE_B(y,z),
  TYPE_C(b,s)

  private boolean incremental; //has get/set
  private String someStr;      //has get/set

  ExecutionMode(boolean incremental,String someStr){
        ///... set things appropriately
  } 
}

If you're setting these values at runtime, my inclination would be that this shouldn't be an enum in the first place - there should be a separate POJO that perhaps contains the values as well as a reference to an enum value.
