doEquals

public boolean doEquals(java.lang.Object obj)

Description copied from interface: Value

In order to index the tables equals and hashCode must be defined. AbstractValue overrides these methods by calling doEquals and doHashCode. Any Value must inherit from abstract Value or override those methods in the same way.
