getNamedPCLRemover(Class<?> clazz)
Looks up and returns the method that removes a PropertyChangeListener for a specified property name from instances of the given class. |
static Method |
getPCLAdder(Class<?> clazz)
Looks up and returns the method that adds a multicast PropertyChangeListener to instances of the given class. |
static Method |
getPCLRemover(Class<?> clazz)
Looks up and returns the method that removes a multicast PropertyChangeListener from instances of the given class. |
static void |
removePropertyChangeListener(Object bean,
Class<?> beanClass,
PropertyChangeListener listener)
Removes a property change listener from the given bean. |
static void |
removePropertyChangeListener(Object bean,
Class<?> beanClass,
String propertyName,

static void |
removePropertyChangeListener(Object bean,
String propertyName,
PropertyChangeListener listener)
Removes a named property change listener from the given bean. |
static boolean |
supportsBoundProperties(Class<?> clazz)
Checks and answers whether the given class supports bound properties, i.e. it provides a pair of multicast event listener registration methods for PropertyChangeListener s:
public void addPropertyChangeListener(PropertyChangeListener x);
