java.lang.Object rice.pastry.socket.SocketSourceRouteManager
public class SocketSourceRouteManager
Class which keeps track of the best routes to remote nodes. This class is also therefore in charge of declaring node death and liveness.
Nested Class Summary | |
---|---|
protected class |
SocketSourceRouteManager.AddressManager
Internal class which is tasked with maintaining the status of a single remote address. |

PING_THROTTLE

PROX_TIMEOUT
millis for the timeout The idea is that we don't want this parameter to change too fast, so this is the timeout for it to increase, you could set this to infinity, but that may be bad because it doesn't account for intermediate link failures |

Constructor |
Method Summary | |
---|---|
void |
bootstrap(EpochInetSocketAddress address,
Message msg)
Method which sends a bootstrap message across the wire. |
void |
checkLiveness(EpochInetSocketAddress address)
Method which FORCES a check of liveness of the remote node. |
SocketNodeHandle |
coalesce(SocketNodeHandle newHandle)
EpochInetSocketAddress -> WeakReference(NodeHandle) Note that it is critical to keep the key == NodeHandle.eaddress. |
void |
connect(EpochInetSocketAddress address,
int appAddress,
AppSocketReceiver receiver,
int timeout)
Method which sends a message across the wire. |
void |
destroy()
Makes this node resign from the network. |
SocketSourceRouteManager.AddressManager |
getAddressManager(EpochInetSocketAddress address)
|
protected SocketSourceRouteManager.AddressManager |
getAddressManager(EpochInetSocketAddress address,
boolean search)
Internal method which returns (or builds) the manager associated with an address |
protected SourceRoute[] |
getAllRoutes(EpochInetSocketAddress destination)
Internal method which returns a list of all possible routes to a given address. |
java.util.HashMap |
getBest()
|
protected SourceRoute |
getBestRoute(EpochInetSocketAddress address)
Internal method which returns the best known route to the given destination |
int |
getLiveness(EpochInetSocketAddress address)
Method which returns the last cached liveness value for the given address. |
SocketCollectionManager |
getManager()
Method which returns the internal manager |
SocketNodeHandle |
getNodeHandle(EpochInetSocketAddress address)
|
protected void |
markAlive(SourceRoute route)
This method should be called when a known route is declared alive. |
protected void |
markDead(EpochInetSocketAddress address)
This method should be called when a known node is declared dead - this is ONLY called when a new epoch of that node is detected. |
protected void |
markDead(SourceRoute route)
This method should be called when a known route is declared dead. |
protected void |
markProximity(SourceRoute route,
int proximity)
This method should be called when a known route has its proximity updated |
protected void |
markSuspected(SourceRoute route)
This method should be called when a known route is declared suspected. |
void |
ping(EpochInetSocketAddress address)
Method which suggests a ping to the remote node. |
int |
proximity(EpochInetSocketAddress address)
Method which returns the last cached proximity value for the given address. |
protected int |
proximity(SourceRoute route)
|
SocketSourceRouteManager.AddressManager |
putAddressManager(EpochInetSocketAddress address,
boolean search)
Should be called while synchronized on nodeHandles |
protected void |
reroute(EpochInetSocketAddress address,
SocketBuffer m)
Reroutes the given message. |
protected int |
rto(SourceRoute route)
|
void |
send(EpochInetSocketAddress address,
Message msg)
|
void |
send(EpochInetSocketAddress address,
SocketBuffer message)
Method which sends a message across the wire. |
