Method Detail

getShortLabel

public abstract java.lang.String getShortLabel()

Description copied from interface: Displayable

Returns a short label that can be displayed to the user. Generally, the value of the returned String is considered translatable and should therefore be placed in an appropriate resource file. When possible, the returned label should be reasonably short enough to show in the navigator or explorer windows but long enough to clearly identify and distinguish the Displayable.

Specified by:

getShortLabel in interface Displayable

Overrides:

getShortLabel in class DefaultDisplayable

See Also:

Displayable.getShortLabel()

getConnectionClassName

public abstract java.lang.String getConnectionClassName()

create

public abstract ConnectionNode create(java.net.URL url)

getLongLabel

public java.lang.String getLongLabel()

Description copied from interface: Displayable

Returns a long label that can be displayed to the user. Generally, the value of the returned String is considered translatable and should therefore be placed in an appropriate resource file. The long label differs from the short label essentially on length. Usually the long label will only be shown on-demand and in places where horizontal space is more available. Examples are the status bar and tooltips.

Specified by:

getLongLabel in interface Displayable

Overrides:

getLongLabel in class DefaultDisplayable

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

See Also:

Displayable.getIcon()

getToolTipText

public java.lang.String getToolTipText()

Description copied from interface: Displayable

Returns the tool tip text to show when the mouse pointer pauses over a UI component that represents this Displayable. In many cases it may be appropriate for this method to return the same value as Displayable.getLongLabel().

Specified by:

getToolTipText in interface Displayable

Overrides:

getToolTipText in class DefaultDisplayable

See Also:

Displayable.getToolTipText()

getChildren

public java.util.Iterator getChildren()

Description copied from class: DefaultFolder

Part of the Element interface. This implementation returns an Iterator over the current list of children.

Specified by:

getChildren in interface Element

Overrides:

getChildren in class DefaultFolder

See Also:

Element.getChildren()

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 observed,
                            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:

observed - the subject whose state has changed.

change - what changed.

getAttributes

public Attributes getAttributes()

Description copied from interface: Element

This method returns an Attributes object that encodes the attributes of the Element. Changing the attribute settings on the return object changes the element attributes. Subclasses should use their super class attributes object to define their own attributes. This allows subclasses to inherit their super class attributes. If a subclass does not wish to inherit attributes, they should first call getAttributes().clear() and define new attributes.

Specified by:

getAttributes in interface Element

Overrides:

getAttributes in class DefaultElement

See Also:

Element.getAttributes()
