Constructor Detail

CompositeErrorMessage

public CompositeErrorMessage(ErrorMessage[] errorMessages)

Constructor for CompositeErrorMessage.

Parameters:: errorMessages - the Array of error messages that are listed togeter. Nulls are ignored, but at least one message is required.

CompositeErrorMessage

public CompositeErrorMessage(Collection<? extends ErrorMessage> errorMessages)

Constructor for CompositeErrorMessage.

Parameters:: errorMessages - the Collection of error messages that are listed together. At least one message is required.

Method Detail

getErrorLevel

public final int getErrorLevel()

The error level is the largest error level in

Specified by:: getErrorLevel in interface ErrorMessage

Returns:: the level of error as an integer.
See Also:: ErrorMessage.getErrorLevel()

iterator

public Iterator<ErrorMessage> iterator()

Gets Error Iterator.

Returns:: the error iterator.

paint

public void paint(PaintTarget target)
           throws PaintException

Description copied from interface: Paintable

Paints the Paintable into a UIDL stream. This method creates the UIDL sequence describing it and outputs it to the given UIDL stream.

It is called when the contents of the component should be painted in response to the component first being shown or having been altered so that its visual representation is changed.

Specified by:: paint in interface Paintable

Parameters:: target - the target UIDL stream where the component should paint itself to.
Throws:: PaintException - if the paint operation failed.
See Also:: Paintable.paint(com.vaadin.terminal.PaintTarget)

addListener

public void addListener(Paintable.RepaintRequestListener listener)

Description copied from interface: ErrorMessage

Error messages are inmodifiable and thus listeners are not needed. This method should be implemented as empty.

Specified by:: addListener in interface ErrorMessage
Specified by:: addListener in interface Paintable

Parameters:: listener - the listener to be added.
See Also:: Paintable.addListener(Paintable.RepaintRequestListener)

removeListener

public void removeListener(Paintable.RepaintRequestListener listener)

Description copied from interface: ErrorMessage

Error messages are inmodifiable and thus listeners are not needed. This method should be implemented as empty.

Specified by:: removeListener in interface ErrorMessage
Specified by:: removeListener in interface Paintable

Parameters:: listener - the listener to be removed.
See Also:: Paintable.removeListener(Paintable.RepaintRequestListener)

requestRepaint

public void requestRepaint()

Description copied from interface: ErrorMessage

Error messages are inmodifiable and thus listeners are not needed. This method should be implemented as empty.

Specified by:: requestRepaint in interface ErrorMessage
Specified by:: requestRepaint in interface Paintable

See Also:: Paintable.requestRepaint()

requestRepaintRequests

public void requestRepaintRequests()

Description copied from interface: Paintable

Request sending of repaint events on any further visible changes. Normally the paintable only send up to one repaint request for listeners after paint as the paintable as the paintable assumes that the listeners already know about the repaint need. This method resets the assumtion. Paint implicitly does the assumtion reset functionality implemented by this method.

This method is normally used only by the terminals to note paintables about implicit repaints (painting the component without actually invoking paint method).

Specified by:: requestRepaintRequests in interface Paintable

toString

public String toString()

Returns a comma separated list of the error messages.

Overrides:: toString in class Object

Returns:: String, comma separated list of error messages.

getDebugId

public String getDebugId()

Description copied from interface: Paintable

Get's currently set debug identifier

Specified by:: getDebugId in interface Paintable

Returns:: current debug id, null if not set

setDebugId

public void setDebugId(String id)

Description copied from interface: Paintable

Adds an unique id for component that get's transferred to terminal for testing purposes. Keeping identifiers unique throughout the Application instance is on programmers responsibility.

Note, that with the current terminal implementation the identifier cannot be changed while the component is visible. This means that the identifier should be set before the component is painted for the first time and kept the same while visible in the client.

Specified by:: setDebugId in interface Paintable

Parameters:: id - A short (< 20 chars) alphanumeric id
