SystemError is a runtime exception caused by error in system. The system error can be shown to the user as it implements IErrorMessage interface, but contains technical information such as stack trace and exception.

SystemError does not support HTML in error messages or stack traces. If HTML messages are required, use {@link UserError} or a custom implementation of ErrorMessage.

__init__(self, *args)
(Constructor)

source code 

Constructor for SystemError with error message and/or causing exception specified.

Parameters:
  • args - tuple of the form
    • ()
    • (message)
      1. the textual error description.
    • (message, cause)
      1. the textual error description.
      2. the throwable causing the system error.
    • (cause)
      1. the throwable causing the system error.
Overrides: object.__init__

getErrorLevel(self)

source code 

Gets the errors level.

Returns:
the level of error as an integer.
Overrides: error_message.IErrorMessage.getErrorLevel

paint(self, target)

source code 

Paints the IPaintable 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.

Parameters:
  • target - the target UIDL stream where the component should paint itself to.
Raises:
Overrides: paintable.IPaintable.paint

See Also: IPaintable.paint

getCause(self)

source code 

Gets cause for the error.

Returns:
the cause.

addListener(self, listener, iface=None)

source code 

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

Parameters:
  • listener - the listener to be added.
Overrides: paintable.IPaintable.addListener
(inherited documentation)

addCallback(self, callback, eventType=None, *args)

source code 
Overrides: paintable.IPaintable.addCallback

removeListener(self, listener, iface=None)

source code 

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

Parameters:
  • listener - the listener to be removed.
Overrides: paintable.IPaintable.removeListener
(inherited documentation)

removeCallback(self, callback, eventType=None)

source code 
Overrides: paintable.IPaintable.removeCallback

requestRepaint(self)

source code 

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

Overrides: paintable.IPaintable.requestRepaint
(inherited documentation)

requestRepaintRequests(self)

source code 

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).

Overrides: paintable.IPaintable.requestRepaintRequests
(inherited documentation)

getDebugId(self)

source code 

Get's currently set debug identifier

Returns:
current debug id, null if not set
Overrides: paintable.IPaintable.getDebugId
(inherited documentation)

setDebugId(self, idd)

source code 

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.

Parameters:
  • idd - A short (< 20 chars) alphanumeric id
Overrides: paintable.IPaintable.setDebugId
(inherited documentation)
