[forge-issues] [JBoss JIRA] (FORGE-386) PersistencePlugin needs to generate hashCode and equals based on Id

PersistencePlugin needs to generate hashCode and equals based on Id ------------------------------------------------------------------- Key: FORGE-386 URL: https://issues.jboss.org/browse/FORGE-386 Project: Forge Issue Type: Enhancement Reporter: Richard Kennard Assignee: Lincoln Baxter III Fix For: 1.0.0.Beta4 Domain classes generated by Forge need to override hashCode/equals if they are to be useful in a UI (among other places). This is hard to do if we know nothing about the semantics of the class, but the PersistencePlugin *does* know something: namely, the Id. The following implementation would suffice for my purposes: @Override public boolean equals(Object that) { if (this == that) { return true; } if (that == null) { return false; } if (getClass() != that.getClass()) { return false; } if (id != null) { return id.equals(((Employer) that).id); } return super.equals(that); } @Override public int hashCode() { if (id != null) { return id.hashCode(); } return super.hashCode(); } But I'm happy for other implementations too.
