Constructor Detail

HttpRoute

public HttpRoute(HttpHost target,
                 java.net.InetAddress local,
                 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(HttpHost target,
                 java.net.InetAddress local,
                 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(HttpHost target,
                 java.net.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(HttpHost target)

Creates a new direct insecure route.

Parameters:

target - the host to which to route

HttpRoute

public HttpRoute(HttpHost target,
                 java.net.InetAddress local,
                 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(HttpHost target,
                 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 HttpHost getTargetHost()

Description copied from interface: RouteInfo

Obtains the target host.

Specified by:

getTargetHost in interface RouteInfo

Returns:

the target host

getLocalAddress

public java.net.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 java.net.InetSocketAddress getLocalSocketAddress()

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 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
