getNodes in interface NodeService

Returns:

an iterator over the set of all nodes

getNodes

public Iterator<Node> getNodes(SegmentId netId)

Description copied from interface: NodeService

Returns an iterator all nodes in a given segment within the domain.

Specified by:

getNodes in interface NodeService

Parameters:

netId - the given segment ID

Returns:

an iterator over the set of all nodes in the given network

getNodes

public Set<Node> getNodes(IpAddress ip)

Description copied from interface: NodeService

Returns all nodes in the domain with a given IP address. Each node returned is guaranteed to be on a unique SegmentId.

If no matches exist, an empty set will be returned.

Specified by:

getNodes in interface NodeService

Parameters:

ip - the given IP address

Returns:

a set of all nodes with the given IP address

getNodes

public Set<Node> getNodes(MacAddress mac,
                 SegmentId segId)

Description copied from interface: NodeService

Returns all nodes in the domain with a given MAC address. Each node returned is guaranteed to have a unique IpAddress within the given SegmentId.

If no matches exist, an empty set will be returned.

Specified by:

getNodes in interface NodeService

Parameters:

mac - the given MAC address

segId - the given segment ID

Returns:

a set of all nodes with the given MAC address

getNodes

public Set<Node> getNodes(ConnectionPoint cp)

Description copied from interface: NodeService

Returns all nodes in the domain where the nodes' most recent location matches the given connection point.

If no matches exist, an empty set will be returned.

Specified by:

getNodes in interface NodeService

Parameters:

cp - the given connection point

Returns:

a set of all nodes at the given location

getNodes

public Set<Node> getNodes(DeviceId device)

Description copied from interface: NodeService

Returns all nodes in the domain where the nodes' most recent location matches a connection point on the given device ID.

If no matches exist, an empty set will be returned.

Specified by:

getNodes in interface NodeService

Parameters:

device - the given device ID

Returns:

a set of all nodes on the given device

getNodes

public Iterator<Node> getNodes(NodeFilter filter)

Description copied from interface: NodeService

Returns an iterator over all nodes which match the given filter in the domain.

Specified by:

getNodes in interface NodeService

Parameters:

filter - the given filter

Returns:

an iterator over the set of all nodes which match the given filter

getNode

public Node getNode(IpAddress ip,
           SegmentId netId)

Description copied from interface: NodeService

Returns a specific node from the domain, based upon the globally-unique combination of IpAddress and SegmentId.

Specified by:

getNode in interface NodeService

Parameters:

ip - IP address

netId - segment ID

Returns:

the matching node; null if not found

getNode

public Node getNode(NodeId id)

Description copied from interface: NodeService

Returns a specific node from the domain, based upon the globally-unique node ID.

Specified by:

getNode in interface NodeService

Parameters:

id - Node ID

Returns:

the matching node; null if not found

addListener

public void addListener(NodeListener listener)

Description copied from interface: NodeService

Registers a listener for all node-related events. This registration will override any prior listener registrations for the same object.

Specified by:

removeListener

public void removeListener(NodeListener listener)

Description copied from interface: NodeService

Unregisters a listener from node-related events, regardless of which node-related events the listener was registered to receive.

Specified by:
