Method Detail

registerAtomicClass

public static void registerAtomicClass(java.lang.Class beanClass)

Automatically creates and registers a JXPathBeanInfo object for the specified class. That object returns true to isAtomic().

registerDynamicClass

public static void registerDynamicClass(java.lang.Class beanClass,
                                        java.lang.Class dynamicPropertyHandlerClass)

Automatically creates and registers a JXPathBeanInfo object for the specified class. That object returns true to isDynamic().

getBeanInfo

public static JXPathBeanInfo getBeanInfo(java.lang.Class beanClass)

Creates and registers a JXPathBeanInfo object for the supplied class. If the class has already been registered, returns the registered JXPathBeanInfo object.

The process of creation of JXPathBeanInfo is as follows:

• If class named <beanClass>XBeanInfo exists, an instance of that class is allocated.
• Otherwise, an instance of JXPathBasicBeanInfo is allocated.

findDynamicBeanInfo

private static JXPathBeanInfo findDynamicBeanInfo(java.lang.Class beanClass)

Find a dynamic bean info if available for any superclasses or interfaces.

findInformant

private static JXPathBeanInfo findInformant(java.lang.Class beanClass)

instantiate

private static java.lang.Object instantiate(java.lang.Class sibling,
                                            java.lang.String className)
                                     throws java.lang.Exception

Try to create an instance of a named class. First try the classloader of "sibling", then try the system classloader.

Throws:

java.lang.Exception
