Class NumberFieldExpression<T extends java.lang.Number,X extends DataObject>

java.lang.Object

uk.ac.ed.epcc.webapp.model.data.FieldExpression<T,X>

uk.ac.ed.epcc.webapp.model.data.NumberFieldExpression<T,X>

Type Parameters:

T - type of expression.

X - type of hosting DataObject

All Implemented Interfaces:

Accessor<T,X>, GroupingSQLValue<T>, SQLAccessor<T,X>, SQLExpression<T>, SQLValue<T>, FieldSQLExpression<T,X>, FieldValue<T,X>, Targetted<T>

public class NumberFieldExpression<T extends java.lang.Number,X extends DataObject>
extends FieldExpression<T,X>

A FieldExpression for Number values. This supports Integer, Long, , Float and values.

Duration objects are stored at millisecond resolution so as to properly implement SQLExpression to store values at a different resolution use a DurationFieldValue.
