Public Constructors

public RouteTracker ( HttpHost target, InetAddress local)

Added in API level 1

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

public RouteTracker ( HttpRoute route)

Added in API level 1

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

Public Methods

public Object clone ()

Added in API level 1

Creates and returns a copy of this Object . The default implementation returns a so-called "shallow" copy: It creates a new instance of the same class and then copies the field values (including object references) from this instance to the new instance. A "deep" copy, in contrast, would also recursively clone nested objects. A subclass that needs to implement this kind of cloning should call super.clone() to create the new instance and then create deep copies of the nested, mutable objects.

Returns
  • a copy of this object.

public final void connectProxy ( HttpHost proxy, boolean secure)

Added in API level 1

Tracks connecting to the first proxy.

Parameters
proxy the proxy connected to
secure true if the route is secure, false otherwise

public final void connectTarget (boolean secure)

Added in API level 1

Tracks connecting to the target.

Parameters
secure true if the route is secure, false otherwise

public final boolean equals ( Object o)

Added in API level 1

Compares this tracked route to another.

Parameters
o the object to compare with
Returns
  • true if the argument is the same tracked route, false

public final int getHopCount ()

Added in API level 1

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.

Returns
  • the number of hops in this route

public final HttpHost getHopTarget (int hop)

Added in API level 1

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.

Parameters
hop index of the hop for which to get the target, 0 for first
Returns
  • the target of the given hop

public final RouteInfo.LayerType getLayerType ()

Added in API level 1

Obtains the layering type of this route. In the presence of proxies, only layering over an end-to-end tunnel is considered.

Returns
  • the layering type

public final InetAddress getLocalAddress ()

Added in API level 1

Obtains the local address to connect from.

Returns
  • the local address, or null

public final HttpHost getProxyHost ()

Added in API level 1

Obtains the first proxy host.

Returns
  • the first proxy in the proxy chain, or null if this route is direct

public final HttpHost getTargetHost ()

Added in API level 1

Obtains the target host.

Returns
  • the target host

public final RouteInfo.TunnelType getTunnelType ()

Added in API level 1

Obtains the tunnel type of this route. If there is a proxy chain, only end-to-end tunnels are considered.

Returns
  • the tunnelling type

public final int hashCode ()

Added in API level 1

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.

Returns
  • the hash code

public final boolean isConnected ()

Added in API level 1

public final boolean isLayered ()

Added in API level 1

Checks whether this route includes a layered protocol. In the presence of proxies, only layering over an end-to-end tunnel is considered.

Returns
  • true if layered, false otherwise

public final boolean isSecure ()

Added in API level 1

Checks whether this route is secure.

Returns
  • true if secure, false otherwise

public final boolean isTunnelled ()

Added in API level 1

Checks whether this route is tunnelled through a proxy. If there is a proxy chain, only end-to-end tunnels are considered.

Returns
  • true if tunnelled end-to-end through at least one proxy, false otherwise

public final void layerProtocol (boolean secure)

Added in API level 1

Tracks layering a protocol.

Parameters
secure true if the route is secure, false otherwise

public final HttpRoute toRoute ()

Added in API level 1

Obtains the tracked route. If a route has been tracked, it is connected . If not connected, nothing has been tracked so far.

Returns
  • the tracked route, or null if nothing has been tracked so far

public final String toString ()

Added in API level 1

Obtains a description of the tracked route.

Returns
  • a human-readable representation of the tracked route

public final void tunnelProxy ( HttpHost proxy, boolean secure)

Added in API level 1

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

public final void tunnelTarget (boolean secure)

Added in API level 1

Tracks tunnelling to the target.

Parameters
secure true if the route is secure, false otherwise
