Method Detail

copyTo

public java.lang.Object copyTo(java.lang.Object object)

Description copied from interface: Copyable

Copies the internal state of this object to the specified copy. If copy is null, then this method should create a new instance of this class and proceed to copy the internal state to the newly created object. Generally, only the persistent state of the object should be copied, but whether or not it is appropriate to copy transient properties is at the discretion of the individual implementor.

Regardless of whether the copy occurs to an existing object or to a newly created object, the return value is object to which this object's state was copied.

There is a standard implementation pattern for the copyTo method that helps avoid problems that arise when a Copyable object is subclassed. The pattern is:

    public Object copyTo( Object target )
    {
      final <this_class> copy =
        target != null ? (<this_class>) target : new <this_class>();
      copyToImpl( copy );
      return copy;
    }

    protected final void copyToImpl( <this_class> copy )
    {
      super.copyToImpl( copy );  //  if necessary
      //  put code here for copying the properties of <this_class>
    }
  

The parameter passed into the copyToImpl method is the same type of this class. The responsibility of copyToImpl is to copy the state of this class through direct access of the fields. The copyToImpl method should not use getters and setters since these may be overridden, causing the state of this class to be incompletely copied.

Specified by:

copyTo in interface Copyable

Parameters:

object - The target object to which the state of this object should be copied. If target is null, then the copyTo method will return a new instance of this class.

Returns:

The object to which the state of this object was copied. If the target was non-null, then the return value is the same as the target object that was passed in; otherwise, the return value is a new instance of this class.

isDirty

public boolean isDirty()

Description copied from interface: Dirtyable

True if the data in the object has been modified.

Specified by:

isDirty in interface Dirtyable

Returns:

true if the data in the object has been modified.

markDirty

public void markDirty(boolean dirty)

Description copied from interface: Dirtyable

Marks the data with the specified dirty state. This method is called markDirty(...) instead of setDirty(...) so that the JavaBeans Introspector will not mistakenly identify "dirty" as a JavaBean property.

Specified by:

markDirty in interface Dirtyable

Parameters:

dirty - If true, sets the object as being dirty; if false, sets the object as being up-to-date.

setOwner

public void setOwner(Dirtyable owner)

Description copied from interface: SubDirtyable

This method should be called to set the document in which a SubDirtyable implementation will be persisted.

Specified by:

setOwner in interface SubDirtyable

Parameters:

owner - The Dirtyable object in which this SubDirtyable will be saved.

getShortLabel

public java.lang.String getShortLabel()

Description copied from class: DefaultDisplayable

This implementation returns a place-holder String.

Specified by:

getShortLabel in interface Displayable

Overrides:

getShortLabel in class DefaultDisplayable

Returns:

a short descriptive label of the Displayable that can be shown to the user.

See Also:

Displayable.getShortLabel()

getLongLabel

public java.lang.String getLongLabel()

Description copied from class: DefaultDisplayable

This implementation delegates to DefaultDisplayable.getShortLabel().

Specified by:

getLongLabel in interface Displayable

Overrides:

getLongLabel in class DefaultDisplayable

Returns:

a long descriptive label of the Displayable that can be shown to the user.

See Also:

Displayable.getLongLabel()

getIcon

public javax.swing.Icon getIcon()

Description copied from class: DefaultFolder

Part of Element interface. The default implementation returns null, which causes a default folder icon to be used.

Specified by:

getIcon in interface Displayable

Overrides:

getIcon in class DefaultFolder

Returns:

the Icon to be displayed for the Displayable.

See Also:

Displayable.getIcon()

getToolTipText

public java.lang.String getToolTipText()

Description copied from class: DefaultDisplayable

This implementation delegates to DefaultDisplayable.getLongLabel().

Specified by:

getToolTipText in interface Displayable

Overrides:

getToolTipText in class DefaultDisplayable

Returns:

the tooltip to show when the mouse pointer pauses over a UI component that represents this Displayable.

See Also:

Displayable.getToolTipText()

attach

public void attach(Observer observer)

Description copied from interface: Subject

Registers an observer interested in being notified when the internal state of the class implementing the Subject interface changes. Implementors should do nothing when the same observer is added more than once.

Specified by:

attach in interface Subject

Parameters:

observer - the Observer interested in change notification messages.

detach

public void detach(Observer observer)

Description copied from interface: Subject

Unregisters an observer that is not interested anymore in being notified when the internal state of the class implementing the Subject interface changes. Implementors should do nothing when the same observer is removed more than once.

Specified by:

detach in interface Subject

Parameters:

observer - the Observer disinterested in change notification messages.

notifyObservers

public void notifyObservers(java.lang.Object subject,
                            UpdateMessage change)

Description copied from interface: Subject

Notifies all observers that the state of the subject has changed.

Specified by:

notifyObservers in interface Subject

Parameters:

subject - the subject whose state has changed.

change - what changed.
