java.lang.Object | |
↳ | android.net.RouteInfo |
Represents a network route.
This is used both to describe static network configuration and live network configuration information. A route contains three pieces of information:
IpPrefix
specifying the network destinations covered by this route.
If this is null
it indicates a default route of the address family (IPv4 or IPv6)
implied by the gateway IP address.
InetAddress
indicating the next hop to use. If this is null
it
indicates a directly-connected route.
null
, but not both. If the
destination and gateway are both specified, they must be of the same address family
(IPv4 or IPv6).
