Class BeanInfoManager

  • public class BeanInfoManager
extends java.lang.Object

    Manages the BeanInfo for one class - contains the BeanInfo, and also a mapping from property name to BeanInfoProperty. There are also static methods for accessing the BeanInfoManager for a class - those mappings are cached permanently so that once the BeanInfoManager is calculated, it doesn't have to be calculated again.
