  - RouteTracker
```
public RouteTracker(HttpHost target,
                    java.net.InetAddress local)
```
    Creates a new route tracker. The target and origin need to be specified at creation time.
    
    Parameters:
    
    target - the host to which to route
    
    local - the local address to route from, or null for the default
  - RouteTracker
```
public RouteTracker(HttpRoute route)
```
    Creates a new tracker for the given route. Only target and origin are taken from the route, everything else remains to be tracked.
    
    Parameters:
    
    route - the route to track
- Method Detail
  - reset
```
public void reset()
```

    4.2
  - connectTarget
```
public final void connectTarget(boolean secure)
```
    Tracks connecting to the target.
    
    Parameters:
    
    secure - true if the route is secure, false otherwise
  - connectProxy
```
public final void connectProxy(HttpHost proxy,
                               boolean secure)
```
    Tracks connecting to the first proxy.
    
    Parameters:
    
    proxy - the proxy connected to
    
    secure - true if the route is secure, false otherwise
  - tunnelTarget
```
public final void tunnelTarget(boolean secure)
```
    Tracks tunnelling to the target.
    
    Parameters:

                              boolean secure)
```
    Tracks tunnelling to a proxy in a proxy chain. This will extend the tracked proxy chain, but it does not mark the route as tunnelled. Only end-to-end tunnels are considered there.
    
    Parameters:
    
    proxy - the proxy tunnelled to
    
    secure - true if the route is secure, false otherwise
  - layerProtocol

    the local address, or null
  - getHopCount
```
public final int getHopCount()
```
    Description copied from interface: RouteInfo
    
    Obtains the number of hops in this route. A direct route has one hop. A route through a proxy has two hops. A route through a chain of n proxies has n+1 hops.
    
    Specified by:
    
    getHopCount in interface RouteInfo
    
    Returns:
    
    the number of hops in this route
  - getHopTarget
```
public final HttpHost getHopTarget(int hop)
```
    Description copied from interface: RouteInfo
    
    Obtains the target of a hop in this route. The target of the last hop is the target host, the target of previous hops is the respective proxy in the chain. For a route through exactly one proxy, target of hop 0 is the proxy and target of hop 1 is the target host.
    
    Specified by:
    
    getHopTarget in interface RouteInfo
    
    Parameters:
    
    hop - index of the hop for which to get the target, 0 for first

    Returns:
    
    true if the argument is the same tracked route, false
  - hashCode
```
public final int hashCode()
```
    Generates a hash code for this tracked route. Route trackers are modifiable and should therefore not be used as lookup keys. Use toRoute to obtain an unmodifiable representation of the tracked route.

    hashCode in class java.lang.Object
    
    Returns:
