Class IntrospectionAdapter

java.lang.Object
  org.apache.myfaces.trinidadinternal.ui.data.bean.IntrospectionAdapter

All Implemented Interfaces:

BeanDOAdapter, DataObject

Deprecated. This class comes from the old Java 1.2 UIX codebase and should not be used anymore.

@Deprecated
public class IntrospectionAdapter
extends java.lang.Object
implements BeanDOAdapter

The IntrospectionAdapter class can adapt a JavaBean-style class into a DataObject. It also supports some features that JavaBeans does not:

1. Public fields (that is - instance variables) are supported
2. Package-private classes are supported - but only if its properties can be retrieved after first casting to a public superclass or public interface. So, for instance, if getFoo() is first defined in a package-private class, the "foo" property won't be accessible. But if it's defined in a public interface that is implemented by that package-private class, then it will be accessible.

IntrospectionAdapter will automatically cache the results of introspection per-class, so it's fairly efficient. Developers may wish to create a more performant adapter class for beans that are performance-critical; see the BuildBeanDOAdapter tool.
