RouteInfo

public final class RouteInfo
extends Object implements Parcelable

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:

a destination 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.
a gateway InetAddress indicating the next hop to use. If this is null it indicates a directly-connected route.
an interface (which may be unspecified).

Either the destination or the gateway may be null, but not both. If the destination and gateway are both specified, they must be of the same address family (IPv4 or IPv6).

Summary

Constants
`int`	`RTN_THROW` Throw route.
`int`	`RTN_UNICAST` Unicast route.
`int`	`RTN_UNREACHABLE` Unreachable route.

Inherited constants

From interface android.os.Parcelable

`int`	`CONTENTS_FILE_DESCRIPTOR` Descriptor bit used with `describeContents()`: indicates that the Parcelable object's flattened representation includes a file descriptor.
`int`	`PARCELABLE_WRITE_RETURN_VALUE` Flag for use with `writeToParcel(Parcel, int)`: the object being written is a return value, that is the result of a function such as "`Parcelable someFunction()`", "`void someFunction(out Parcelable)`", or "`void someFunction(inout Parcelable)`".

Fields
`public static final Creator<RouteInfo>`	`CREATOR` Implement the Parcelable interface.

Public methods

Inherited methods

From class java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

From interface android.os.Parcelable

`abstract int`	`describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
`abstract void`	`writeToParcel(Parcel dest, int flags)` Flatten this object in to a Parcel.
