Interface SQLAccessor<T,R>

Type Parameters:

T - type of result value

R - target object

All Superinterfaces:

Accessor<T,R>, GroupingSQLValue<T>, SQLValue<T>, Targetted<T>

All Known Subinterfaces:

FieldSQLExpression<T,X>, FieldValue<T,X>

All Known Implementing Classes:

public interface SQLAccessor<T,R>
extends Accessor<T,R>, GroupingSQLValue<T>

A combination of Accessor and SQLValue. In general the two behaviours are distinct though related. This interface is for leaf level entities (database fields) where we always need to support both behaviours so it is sensible to implement them in the same object.
