public DefaultNodeLocation(DeviceId id,
                   InterfaceId intfId)

Constructs a node location at the given device and interface, using the current system timestamp.

Parameters:

id - given device ID

intfId - given interface ID

DefaultNodeLocation

protected DefaultNodeLocation(DeviceId id,
                   InterfaceId intfId,
                   long ts)

Constructs a node location for the given device, interface, and timestamp.

Parameters:

id - given device ID

intfId - given interface ID

ts - timestamp

DefaultNodeLocation

public DefaultNodeLocation(ConnectionPoint cp)

Constructs a node location from the given connection point. If the connection point element ID is not a device ID, then an IllegalArgumentException will be thrown.

Parameters:

cp - connection point

Throws:

IllegalArgumentException - if connection point is not on device
