Method Summary

MethodMeta	getMethodMeta(java.lang.Class clazz, java.lang.reflect.Method method, java.util.Locale locale, java.lang.ClassLoader loader) test if the method is applicable by calling isApplicable(Class, Method, Locale, ClassLoader) and creates new property via newMethodMeta(Class, Method, Locale, ClassLoader) if yes.
protected abstract boolean	isApplicable(java.lang.Class clazz, java.lang.reflect.Method method, java.util.Locale locale, java.lang.ClassLoader loader) test if given method is to be observed
protected abstract MethodMeta	newMethodMeta(java.lang.Class clazz, java.lang.reflect.Method method, java.util.Locale locale, java.lang.ClassLoader loader) instantiate new method metadata object

getMethodMeta

public MethodMeta getMethodMeta(java.lang.Class clazz,
                                java.lang.reflect.Method method,
                                java.util.Locale locale,
                                java.lang.ClassLoader loader)
                         throws DecorationException

test if the method is applicable by calling isApplicable(Class, Method, Locale, ClassLoader) and creates new property via newMethodMeta(Class, Method, Locale, ClassLoader) if yes.

returns null if not applicable

Specified by:

getMethodMeta in interface Selector

Parameters:

clazz - is POJO's class

method - which is to be to be examined

locale - to be used when creating the metadata

loader - is the classloader to be used to load any resource file (if required)

Returns:

a valid MethodMeta if this method a suitable for inclusion in State and null if it is not

Throws:

DecorationException - in case of internal error

isApplicable

protected abstract boolean isApplicable(java.lang.Class clazz,
                                        java.lang.reflect.Method method,
                                        java.util.Locale locale,
                                        java.lang.ClassLoader loader)
                                 throws DecorationException

test if given method is to be observed

Parameters:

clazz - is POJO's class

method - which is to be to be examined

locale - to be used when creating the metadata

loader - is the classloader to be used to load any resource file (if required)

Returns:

true if this is a suitable for State method, otherwise false.

Throws:

DecorationException

newMethodMeta

protected abstract MethodMeta newMethodMeta(java.lang.Class clazz,
                                            java.lang.reflect.Method method,
                                            java.util.Locale locale,
                                            java.lang.ClassLoader loader)
                                     throws DecorationException

instantiate new method metadata object

Parameters:

clazz - is POJO's class

method - which is to be to be examined

locale - to be used when creating the metadata

loader - is the classloader to be used to load any resource file (if required)

Returns:

new and initialized MethodMeta object

Throws:

DecorationException - in case of internal error
