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
