Class BeanInfoCache

java.lang.Object
  org.apache.axis2.classloader.BeanInfoCache

public final class BeanInfoCache
extends Object

BeanInfo cache that stores introspection results by bean class and stop class. This goes beyond the caching provided by the JRE, which only caches the results of Introspector.getBeanInfo(Class), but not the results of Introspector.getBeanInfo(Class, Class) (with non null stop class).

To avoid class loader leaks, this class should not be used as a singleton if the introspected classes are loaded from class loaders that are children of the class loader which holds the reference to the cache. In such scenarios, use getCachedBeanInfo(Class, Class).

Method Detail

getBeanInfo

public BeanInfo getBeanInfo(Class<?> beanClass,
                            Class<?> stopClass)
                     throws IntrospectionException

Introspect on a Java bean and return a cached BeanInfo object.

Parameters:

beanClass - The bean class to be analyzed.

stopClass - The base class at which to stop the analysis; may be null.

Returns:

A BeanInfo object describing the target bean.

Throws:

IntrospectionException - if an exception occurs during introspection.

getCachedBeanInfo

public static BeanInfo getCachedBeanInfo(Class<?> beanClass,
                                         Class<?> stopClass)
                                  throws IntrospectionException

Locate an appropriate BeanInfoCache and return a cached BeanInfo object. This method ensures that caching the BeanInfo object will not result in a class loader leak.

Parameters:

beanClass - The bean class to be analyzed.

stopClass - The base class at which to stop the analysis; may be null.

Returns:

A BeanInfo object describing the target bean.

Throws:

IntrospectionException - if an exception occurs during introspection.
