 public abstract class AbstractAction extends Object implements Action, Cloneable, Serializable This class provides default implementations for the JFCActioninterface. Standard behaviors like the get and set methods forActionobject properties (icon, text, and enabled) are defined here. The developer need only subclass this abstract class and define theactionPerformedmethod.Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans™ has been added to the java.beanspackage. Please seeXMLEncoder.- Since:
- 1.2

Constructor Detail- 
AbstractActionpublic AbstractAction() Creates anAction.
 - 
AbstractActionpublic AbstractAction(String name) Creates anActionwith the specified name.- Parameters:
- name- the name (- Action.NAME) for the action; a value of- nullis ignored
 
 
- 
 - 
Method Detail- 
getValuepublic Object getValue(String key) Gets theObjectassociated with the specified key.- Specified by:
- getValuein interface- Action
- Parameters:
- key- a string containing the specified- key
- Returns:
- the binding Objectstored with this key; if there are no keys, it will returnnull
- See Also:
- Action.getValue(java.lang.String)
 
 - 
putValuepublic void putValue(String key, Object newValue) Sets theValueassociated with the specified key.- Specified by:
- putValuein interface- Action
- Parameters:
- key- the- Stringthat identifies the stored object
- newValue- the- Objectto store using this key
- See Also:
- Action.putValue(java.lang.String, java.lang.Object)
 
 - 
isEnabledpublic boolean isEnabled() Returns true if the action is enabled.- Specified by:
- isEnabledin interface- Action
- Returns:
- true if the action is enabled, false otherwise
- See Also:
- Action.isEnabled()
 
 - 
setEnabledpublic void setEnabled(boolean newValue) Sets whether theActionis enabled. The default istrue.- Specified by:
- setEnabledin interface- Action
- Parameters:
- newValue-- trueto enable the action,- falseto disable it
- See Also:
- Action.setEnabled(boolean)
 
 - 
getKeyspublic Object[] getKeys() Returns an array ofObjects which are keys for which values have been set for thisAbstractAction, ornullif no keys have values set.- Returns:
- an array of key objects, or nullif no keys have values set
- Since:
- 1.3
 
 - 
firePropertyChangeprotected void firePropertyChange(String propertyName, Object oldValue, Object newValue) Supports reporting bound property changes. This method can be called when a bound property has changed and it will send the appropriatePropertyChangeEventto any registeredPropertyChangeListeners.- Parameters:
- propertyName- the name of the property that has changed
- oldValue- the old value of the property
- newValue- the new value of the property
 
 - 
addPropertyChangeListenerpublic void addPropertyChangeListener(PropertyChangeListener listener) Adds aPropertyChangeListenerto the listener list. The listener is registered for all properties.A PropertyChangeEventwill get fired in response to setting a bound property, e.g.setFont,setBackground, orsetForeground. Note that if the current component is inheriting its foreground, background, or font from its container, then no event will be fired in response to a change in the inherited property.- Specified by:
- addPropertyChangeListenerin interface- Action
- Parameters:
- listener- The- PropertyChangeListenerto be added
- See Also:
- Action.addPropertyChangeListener(java.beans.PropertyChangeListener)
 
 - 
removePropertyChangeListenerpublic void removePropertyChangeListener(PropertyChangeListener listener) Removes aPropertyChangeListenerfrom the listener list. This removes aPropertyChangeListenerthat was registered for all properties.- Specified by:
- removePropertyChangeListenerin interface- Action
- Parameters:
- listener- the- PropertyChangeListenerto be removed
- See Also:
- Action.removePropertyChangeListener(java.beans.PropertyChangeListener)
 
 - 
getPropertyChangeListenerspublic PropertyChangeListener[] getPropertyChangeListeners() Returns an array of all thePropertyChangeListeners added to this AbstractAction with addPropertyChangeListener().- Returns:
- all of the PropertyChangeListeners added or an empty array if no listeners have been added
- Since:
- 1.4
 
 - 
cloneprotected Object clone() throws CloneNotSupportedException Clones the abstract action. This gives the clone its own copy of the key/value list, which is not handled for you byObject.clone().- Overrides:
- clonein class- Object
- Returns:
- a clone of this instance.
- Throws:
- CloneNotSupportedException- if the object's class does not support the- Cloneableinterface. Subclasses that override the- clonemethod can also throw this exception to indicate that an instance cannot be cloned.

- Cloneable
