  - RouteTracker
```
public RouteTracker(org.apache.http.HttpHost target,
            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()
```
    Since:
    
    4.2
  - connectTarget
```
public void connectTarget(boolean secure)
```
    Tracks connecting to the target.
    
    Parameters:
    secure - true if the route is secure, false otherwise
  - connectProxy
```
public void connectProxy(org.apache.http.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 void tunnelTarget(boolean secure)
```
    Tracks tunnelling to the target.
    
    Parameters:
    secure - true if the route is secure, false otherwise
  - tunnelProxy
```
public void tunnelProxy(org.apache.http.HttpHost proxy,
               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
```
public void layerProtocol(boolean secure)
```
    Tracks layering a protocol.
    
    Parameters:
    secure - true if the route is secure, false otherwise
  - getTargetHost
```
public org.apache.http.HttpHost getTargetHost()
```
    Description copied from interface: RouteInfo
    
    Obtains the target host.
    
    Specified by:
    
    getTargetHost in interface RouteInfo
    
    Returns:
    the target host
  - getLocalAddress
```
public InetAddress getLocalAddress()
```
    Description copied from interface: RouteInfo
    
    Obtains the local address to connect from.
    
    Specified by:
    
    getLocalAddress in interface RouteInfo
    
    Returns:
    the local address, or null
  - getHopCount
```
public 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 org.apache.http.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:
    the target of the given hop
  - getProxyHost

  - toRoute
```
public HttpRoute toRoute()

    Returns:
    true if the argument is the same tracked route, false
  - hashCode
```
public 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 Object
    
    Returns:
    the hash code
