Method Details

getBeanPropertyNameFromGetter

public static String getBeanPropertyNameFromGetter(Method method)

Returns the bean version of the property name if the method is a getter, or returns null if the method is not a getter

Parameters:

method - The method to get the property name from

Returns:

The java-bean version of the property name or null if the method is not a java-bean getter

getChangeEvents

public static PropertyChangeEvent[] getChangeEvents(ClassReflectionHelper helper,
 Object oldBean,
 Object newBean)

Gets the set of change events by comparing two different beans. If the beans implement Map then they are considered to be bean-like maps

Parameters:

helper - A ClassReflectionHelper to use for analyzing classes

oldBean - a non-null current bean

newBean - a non-null new bean

Returns:

a possibly zero length but never null list of the change events between the two beans

convertJavaBeanToBeanLikeMap

public static Map<String,Object> convertJavaBeanToBeanLikeMap(ClassReflectionHelper helper,
 Object bean)

Converts a Java bean to a bean-like Map

Parameters:

helper - A ClassReflectionHelper to use for analyzing classes

bean - a non-null bean to convert

Returns:

a possibly zero length but never null bean-like map. All properties of the bean are filled in, even if the value of the property is null
