Class DirectBean

java.lang.Object
  org.joda.beans.impl.direct.DirectBean

All Implemented Interfaces:

Bean

public abstract class DirectBean
extends Object
implements Bean

A bean implementation designed for use by the code generator.

This implementation uses direct access via #propertyGet(String) and #propertySet(String, Object) to avoid reflection.

For code generation, the bean must directly extend this class and have a no-arguments constructor.
