Constructor Detail

Entity

public Entity(MacAddress mac,
      VId vid,
      IpAddress ip,
      DataPathId dpid,
      BigPortNumber port,
      int contollerId)

Constructs a new entity using MAC, VID, IP, data path id and port.

Parameters:

mac - the MAC address

vid - the VID

ip - the IP address

dpid - the Switch DPID

port - the port

contollerId - the hash of the controller instance id

Entity

public Entity(MacAddress mac,
      VId vid,
      IpAddress ip,
      DataPathId dpid,
      BigPortNumber port,
      boolean shared,
      int contollerId)

Constructs a new entity using MAC, VID, IP, data path id, port and shared.

Constructor has been added to help create an entity object with timestamp 0.

A shared flag is added to indicate that the entity has been received from another controller in the cluster. A shared flag value of true will cause the lastAccessed time to be set to 0 indicating that the entity has been learned from another controller in the cluster.

Parameters:

mac - the MAC address

vid - the VID

ip - the IP address

dpid - the Switch DPID

port - the port

shared - flag indicating shared entity

contollerId - the hash of the controller instance id

      IpAddress ip,
      DataPathId dpid,
      BigPortNumber port,
      long age,
      int contollerId)

Constructs a new entity using MAC, VID, IP, data path id and port.

Parameters:

mac - the MAC address

vid - the VID

ip - the IP address

dpid - the Switch DPID

port - the port

age - age flag

contollerId - the hash of the controller instance id
