 public BeanDescriptor(Class<?> beanClass) {
this(beanClass, null);
}

|
BeanDescriptor(BeanDescriptor old) {
super(old);
beanClassRef = old.beanClassRef;
customizerClassRef = old.customizerClassRef;
} |
public BeanDescriptor(Class<?> beanClass,
Class<?> customizerClass) {
this.beanClassRef = getWeakReference((Class)beanClass);
this.customizerClassRef = getWeakReference((Class)customizerClass);
String name = beanClass.getName();
while (name.indexOf('.') >= 0) {
name = name.substring(name.indexOf('.')+1);
}
setName(name);
} Create a BeanDescriptor for a bean that has a customizer. Parameters:
