Class ClassificationSQLValue<H extends uk.ac.ed.epcc.webapp.model.data.DataObject,T extends uk.ac.ed.epcc.webapp.model.data.DataObject>

java.lang.Object

uk.ac.ed.epcc.safe.accounting.db.ClassificationSQLValue<H,T>

Type Parameters:

H - type of owning object

T - type of remote object

All Implemented Interfaces:

uk.ac.ed.epcc.webapp.jdbc.expr.FilterProvider<H,java.lang.String>, uk.ac.ed.epcc.webapp.jdbc.expr.SQLValue<java.lang.String>, uk.ac.ed.epcc.webapp.Targetted<java.lang.String>

public class ClassificationSQLValue<H extends uk.ac.ed.epcc.webapp.model.data.DataObject,T extends uk.ac.ed.epcc.webapp.model.data.DataObject>
extends java.lang.Object
implements uk.ac.ed.epcc.webapp.jdbc.expr.SQLValue<java.lang.String>, uk.ac.ed.epcc.webapp.jdbc.expr.FilterProvider<H,java.lang.String>

An SQLAccessor that retrieves the string representation of an object pointed to by a reference field. Unlike a simple string cast it also supports filtering. It will also generate the string Unknown on a null reference
