Method Detail

getTargetHost

HttpHost getTargetHost()
Obtains the target host.

Returns:
the target host

getLocalAddress

InetAddress getLocalAddress()
Obtains the local address to connect from.

Returns:
the local address, or null

getHopCount

int getHopCount()
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

getHopTarget

HttpHost getHopTarget(int hop)
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
Throws:
IllegalArgumentException - if the argument is negative or not less than getHopCount()

getProxyHost

HttpHost getProxyHost()
Obtains the first proxy host.

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

getTunnelType

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

Returns:
the tunnelling type

isTunnelled

boolean isTunnelled()
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

getLayerType

RouteInfo.LayerType getLayerType()
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

isLayered

boolean isLayered()
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

isSecure

boolean isSecure()
Checks whether this route is secure.

Returns:
true if secure, false otherwise
