Class GroupBeanHandler

java.lang.Object

org.jboss.xb.builder.runtime.GroupBeanHandler

All Implemented Interfaces:

ParticleHandler

public class GroupBeanHandler
extends Object
implements ParticleHandler

A GroupBeanHandler. Before creating a new instance for the group during unmarshalling, this handler will try to obtain the current value of the group from the parent object using the property the group is bound to. If the current group value is not null then it will be returned, otherwise a new instance will be created. This is necessary to support unordered sequences. If the property for the group is not readable then the step to get the group value will be skipped. It doesn't have to be a requirement for the property to be readable.
