public boolean validate(javax.persistence.EntityManager em,
                        StringBuffer errmsg)

Validates a recently created entry, before it has been put into the database. Adds any error message text to errmsg.

true if ok

fetchVecs

public void fetchVecs()

This is meant to cause JPA load vectors that are not automatically loaded. The idea is, they can be accessible through this object even after the EntityManager is closed.

getLongId

public long getLongId()

A very cludgy way to call getId() regardless of whether it's returning int or long

ignores

public boolean ignores(String fieldName)

In some classes, certain fields should not be displayed or modified unless certain conditions apply. E.g., some fields of a User object only applies in certain programs. Implementing classes override this method as needed to impose appropriate restrictions.

reflectToString

public String reflectToString()

Prints out all fields of the object that, according to the appropriate annotations, we want printed
