### Constructor Detail

#### HttpRoute

    public HttpRoute(org.apache.http.HttpHost target,
             InetAddress local,
             org.apache.http.HttpHost[] proxies,
             boolean secure,
             RouteInfo.TunnelType tunnelled,
             RouteInfo.LayerType layered)

Creates a new route with all attributes specified explicitly.

Parameters:
  `target` - the host to which to route
  `local` - the local address to route from, or `null` for the default
  `proxies` - the proxy chain to use, or `null` for a direct route
  `secure` - `true` if the route is (to be) secure, `false` otherwise
  `tunnelled` - the tunnel type of this route
  `layered` - the layering type of this route

#### HttpRoute

    public HttpRoute(org.apache.http.HttpHost target,
             InetAddress local,
             org.apache.http.HttpHost proxy,
             boolean secure,
             RouteInfo.TunnelType tunnelled,
             RouteInfo.LayerType layered)

Creates a new route with at most one proxy.

Parameters:
  `target` - the host to which to route
  `local` - the local address to route from, or `null` for the default
  `proxy` - the proxy to use, or `null` for a direct route
  `secure` - `true` if the route is (to be) secure, `false` otherwise
  `tunnelled` - `true` if the route is (to be) tunnelled via the proxy, `false` otherwise
  `layered` - `true` if the route includes a layered protocol, `false` otherwise

#### HttpRoute

    public HttpRoute(org.apache.http.HttpHost target,
             InetAddress local,
             boolean secure)

Creates a new direct route. That is a route without a proxy.

Parameters:
  `target` - the host to which to route
  `local` - the local address to route from, or `null` for the default
  `secure` - `true` if the route is (to be) secure, `false` otherwise

#### HttpRoute

    public HttpRoute(org.apache.http.HttpHost target)

Creates a new direct insecure route.

Parameters:
  `target` - the host to which to route

#### HttpRoute

    public HttpRoute(org.apache.http.HttpHost target,
             InetAddress local,
             org.apache.http.HttpHost proxy,
             boolean secure)

Creates a new route through a proxy. When using this constructor, the `proxy` MUST be given. For convenience, it is assumed that a secure connection will be layered over a tunnel through the proxy.

Parameters:
  `target` - the host to which to route
  `local` - the local address to route from, or `null` for the default
  `proxy` - the proxy to use
  `secure` - `true` if the route is (to be) secure, `false` otherwise

#### HttpRoute

    public HttpRoute(org.apache.http.HttpHost target,
             org.apache.http.HttpHost proxy)

Creates a new plain route through a proxy.

Parameters:
  `target` - the host to which to route
  `proxy` - the proxy to use
Since:
  4.3

### Method Detail

#### getTargetHost

    public org.apache.http.HttpHost getTargetHost()

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`

#### getLocalSocketAddress

    public InetSocketAddress getLocalSocketAddress()

#### getHopCount

    public int getHopCount()

Description copied from interface: `RouteInfo`
