All Known Implementing Classes:

OSMXAnchorType, OSMXGenSpecType, OSMXObjectSetType, OSMXObjectType, OSMXPositionedText, OSMXRelationshipSetType

public interface PositionedElement

Represents an element that occupies a location on a graphical surface.

Method Summary

void	addPositionListener(PositionListener pl) Registers an object to listen for position changes by this element.
int	getOrder() Returns the z-coordinate of the element.
int	getX() Returns the x-coordinate of the element.
int	getY() Returns the y-coordinate of the element.
boolean	isSetPosition() Indicates whether this element has explicitly been given an x and y coordinate position.
void	removePositionListener(PositionListener pl) Un-registers an object currently listening for position change events.
void	setOrder(int value) Changes the value of the order attribute and notifies the position change listeners.
void	setX(int value) Changes the x-coordinate position and causes any position listeners to be notified.
void	setY(int value) Changes the y-coordinate position and causes any position listeners to be notified.
void	unsetX() Clears the current setting for the x attribute.
void	unsetY() Clears the current setting for the y attribute.

Method Detail

getX

public int getX()

Returns the x-coordinate of the element.

Returns:

The x-coordinate of the element.

getY

public int getY()

Returns the y-coordinate of the element.

Returns:

The y-coordinate of the element.

getOrder

public int getOrder()

Returns the z-coordinate of the element.

Returns:

The z-coordinate of the element.

setX

public void setX(int value)

Changes the x-coordinate position and causes any position listeners to be notified.

Parameters:

value - The new x-coordinate position of this element.

setY

public void setY(int value)

Changes the y-coordinate position and causes any position listeners to be notified.

Parameters:

value - The new y-coordinate position of this element.

setOrder

public void setOrder(int value)

Changes the value of the order attribute and notifies the position change listeners.

Parameters:

value - The new value for the z-order of this element.

addPositionListener

public void addPositionListener(PositionListener pl)

Registers an object to listen for position changes by this element.

Parameters:

pl - The object to register for position change event notification.

removePositionListener

public void removePositionListener(PositionListener pl)

Un-registers an object currently listening for position change events.

Parameters:

pl - The object to remove from the notification list for position changes.

isSetPosition

public boolean isSetPosition()

Indicates whether this element has explicitly been given an x and y coordinate position.

Returns:

true if both the x and y coordinate attributes have been set; false otherwise.

unsetX

public void unsetX()

Clears the current setting for the x attribute.

unsetY

public void unsetY()

Clears the current setting for the y attribute.
