`RouteInfo.LayerType` `getLayerType()` Obtains the layering type of this route.
`InetAddress` `getLocalAddress()` Obtains the local address to connect from.
`HttpHost` `getProxyHost()` Obtains the first proxy host.
`HttpHost` `getTargetHost()` Obtains the target host.
`RouteInfo.TunnelType` `getTunnelType()` Obtains the tunnel type of this route.
`boolean` `isLayered()` Checks whether this route includes a layered protocol.
`boolean` `isSecure()` Checks whether this route is secure.
`boolean` `isTunnelled()` Checks whether this route is tunnelled through a proxy.

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
