UiDeviceLink

public UiDeviceLink(UiTopology topology,
                    UiLinkId id)

Creates a device to device UI link.

Parameters:

topology - parent topology

id - canonicalized link identifier

Method Detail

endPointA

public String endPointA()

Description copied from class: UiLink

Returns the identifier of end-point A in string form.

Specified by:

endPointA in class UiLink

Returns:

end point A identifier

endPointB

public String endPointB()

Description copied from class: UiLink

Returns the identifier of end-point B in string form.

Specified by:

endPointB in class UiLink

Returns:

end point B identifier

endPortA

public String endPortA()

Description copied from class: UiLink

Returns the port number (as a string) for end-point A, if applicable. This default implementation returns null, indicating not-applicable. Subclasses only need to override this method if end-point A has an associated port.

Overrides:

endPortA in class UiLink

Returns:

port number for end-point A

endPortB

public String endPortB()

Description copied from class: UiLink

Returns the port number (as a string) for end-point B, if applicable. This default implementation returns null, indicating not-applicable. Subclasses only need to override this method if end-point B has an associated port.

Overrides:

endPortB in class UiLink

Returns:

port number for end-point B

destroy

protected void destroy()

Description copied from class: UiElement

Removes all external references, and prepares the instance for garbage collection. This default implementation does nothing.

Overrides:

destroy in class UiElement

attachBackingLink

public void attachBackingLink(Link link)

Parameters:

link - backing link to attach

Throws:

IllegalArgumentException - if the link is not appropriate

detachBackingLink

public boolean detachBackingLink(Link link)

Detaches the given backing link from this UI link, returning true if the reverse link is still attached, or false otherwise.

Parameters:

link - the backing link to detach

Returns:

true if other link still attached, false otherwise

Throws:

IllegalArgumentException - if the link is not appropriate

deviceA

public DeviceId deviceA()

Returns the identity of device A.

Returns:

device A ID

portA

public PortNumber portA()

Returns:

port A

deviceB

public DeviceId deviceB()

Returns the identity of device B.

Returns:

device B ID

portB

public PortNumber portB()

Returns the port number of device B.

Returns:

port B

linkAtoB

public Link linkAtoB()

Returns backing link from A to B.

Returns:

backing link A to B

linkBtoA

public Link linkBtoA()

Returns backing link from B to A.

Returns:

backing link B to A
