java.beans
class: GenericBeanInfo [javadoc | source]

java.lang.Object
   java.beans.SimpleBeanInfo
      java.beans.GenericBeanInfo

All Implemented Interfaces:
    BeanInfo

Package private implementation support class for Introspector's internal use.

Mostly this is used as a placeholder for the descriptors.

Constructor:
GenericBeanInfo(GenericBeanInfo old) { beanDescriptor = new BeanDescriptor(old.beanDescriptor); if (old.events != null) { int len = old.events.length; events = new EventSetDescriptor[len]; for (int i = 0; i < len; i++) { events[i] = new EventSetDescriptor(old.events[i]); } } defaultEvent = old.defaultEvent; if (old.properties != null) { int len = old.properties.length; properties = new PropertyDescriptor[len]; for (int i = 0; i < len; i++) { PropertyDescriptor oldp = old.properties[i]; if (oldp instanceof IndexedPropertyDescriptor) { properties[i] = new IndexedPropertyDescriptor( (IndexedPropertyDescriptor) oldp); } else { properties[i] = new PropertyDescriptor(oldp); } } } defaultProperty = old.defaultProperty; if (old.methods != null) { int len = old.methods.length; methods = new MethodDescriptor[len]; for (int i = 0; i < len; i++) { methods[i] = new MethodDescriptor(old.methods[i]); } } this.targetBeanInfoRef = old.targetBeanInfoRef; } Package-private dup constructor This must isolate the new object from any changes to the old object.
public GenericBeanInfo(BeanDescriptor beanDescriptor, EventSetDescriptor[] events, int defaultEvent, PropertyDescriptor[] properties, int defaultProperty, MethodDescriptor[] methods, BeanInfo targetBeanInfo) { this.beanDescriptor = beanDescriptor; this.events = events; this.defaultEvent = defaultEvent; this.properties = properties; this.defaultProperty = defaultProperty; this.methods = methods; this.targetBeanInfoRef = new SoftReference< BeanInfo >(targetBeanInfo); }
