Package com.exedio.cope

Class View<E>

java.lang.Object

com.exedio.cope.Feature

com.exedio.cope.View<E>

All Implemented Interfaces:

Function<E>, Selectable<E>, Serializable

Direct Known Subclasses:

CoalesceView, NumberView, StringView

public abstract class View<E>
extends Feature
implements Function<E>

A view represents a value computed from the fields of a Type. The computation is available both in Java and SQL, so you can use views in search conditions.
