Network

public class Network
extends Object implements Parcelable

java.lang.Object
↳	android.net.Network

Identifies a Network. This is supplied to applications via ConnectivityManager.NetworkCallback in response to the active ConnectivityManager#requestNetwork or passive ConnectivityManager#registerNetworkCallback calls. It is used to direct traffic to the given Network, either on a Socket basis through a targeted SocketFactory or process-wide via ConnectivityManager#bindProcessToNetwork.

public static final Creator<Network> CREATOR

Public methods

bindSocket

public void bindSocket (DatagramSocket socket)

Binds the specified DatagramSocket to this Network. All data traffic on the socket will be sent on this Network, irrespective of any process-wide network binding set by ConnectivityManager#bindProcessToNetwork. The socket must not be connected.

Parameters
`socket`	`DatagramSocket`

Throws
`IOException`

bindSocket

public void bindSocket (Socket socket)

Binds the specified Socket to this Network. All data traffic on the socket will be sent on this Network, irrespective of any process-wide network binding set by ConnectivityManager#bindProcessToNetwork. The socket must not be connected.

Parameters
`socket`	`Socket`

Throws
`IOException`

bindSocket

public void bindSocket (FileDescriptor fd)

Binds the specified FileDescriptor to this Network. All data traffic on the socket represented by this file descriptor will be sent on this Network, irrespective of any process-wide network binding set by ConnectivityManager#bindProcessToNetwork. The socket must not be connected.

Parameters
`fd`	`FileDescriptor`

Throws
`IOException`

describeContents

public int describeContents ()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(android.os.Parcel, int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

Returns
`int`	a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either `0` or `CONTENTS_FILE_DESCRIPTOR`

equals

public boolean equals (Object obj)

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

It is reflexive: for any non-null reference value x, x.equals(x) should return true.
It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
For any non-null reference value x, x.equals(null) should return false.

The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x and y, this method returns true if and only if x and y refer to the same object (x == y has the value true).

Note that it is generally necessary to override the hashCode method whenever this method is overridden, so as to maintain the general contract for the hashCode method, which states that equal objects must have equal hash codes.

Parameters
`obj`	`Object`: This value may be `null`.

Returns
`boolean`	`true` if this object is the same as the obj argument; `false` otherwise.

fromNetworkHandle

public static Network fromNetworkHandle (long networkHandle)

Returns a Network object given a handle returned from getNetworkHandle().

Parameters
`networkHandle`	`long`: a handle returned from `getNetworkHandle()`.

Returns
`Network`	A `Network` object derived from `networkHandle`.

getAllByName

public InetAddress[] getAllByName (String host)

Operates the same as InetAddress.getAllByName except that host resolution is done on this network.

Parameters
`host`	`String`: the hostname or literal IP string to be resolved.

Returns
`InetAddress[]`	the array of addresses associated with the specified host.

Throws
`UnknownHostException`	if the address lookup fails.

getByName

public InetAddress getByName (String host)

Operates the same as InetAddress.getByName except that host resolution is done on this network.

Parameters
`host`	`String`: the hostname to be resolved to an address or `null`.

Returns
`InetAddress`	the `InetAddress` instance representing the host.

Throws
`UnknownHostException`	if the address lookup fails.

getNetworkHandle

public long getNetworkHandle ()

Returns a handle representing this Network, for use with the NDK API.

Returns
`long`

getSocketFactory

public SocketFactory getSocketFactory ()

Returns a SocketFactory bound to this network. Any Socket created by this factory will have its traffic sent over this Network. Note that if this Network ever disconnects, this factory and any Socket it produced in the past or future will cease to work.

Returns
`SocketFactory`	a `SocketFactory` which produces `Socket` instances bound to this `Network`.

hashCode

public int hashCode ()

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.

The general contract of hashCode is:

Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.
It is not required that if two objects are unequal according to the equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java™ programming language.)

Returns
`int`	a hash code value for this object.

openConnection

public URLConnection openConnection (URL url)

Opens the specified URL on this Network, such that all traffic will be sent on this Network. The URL protocol must be HTTP or HTTPS.

Parameters
`url`	`URL`

Returns
`URLConnection`	a `URLConnection` to the resource referred to by this URL.

Throws
`MalformedURLException`	if the URL protocol is not HTTP or HTTPS.
`IOException`	if an error occurs while opening the connection.

See also:

URL.openConnection()

openConnection

public URLConnection openConnection (URL url, 
                Proxy proxy)

Opens the specified URL on this Network, such that all traffic will be sent on this Network. The URL protocol must be HTTP or HTTPS.

Parameters
`url`	`URL`
`proxy`	`Proxy`: the proxy through which the connection will be established.

Returns
`URLConnection`	a `URLConnection` to the resource referred to by this URL.

Throws
`MalformedURLException`	if the URL protocol is not HTTP or HTTPS.
`IllegalArgumentException`	if the argument proxy is null.
`IOException`	if an error occurs while opening the connection.

See also:

URL.openConnection()

toString

public String toString ()

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())

Returns
`String`	a string representation of the object.

writeToParcel

public void writeToParcel (Parcel dest, 
                int flags)

Flatten this object in to a Parcel.

Parameters
`dest`	`Parcel`: The Parcel in which the object should be written.
`flags`	`int`: Additional flags about how the object should be written. May be 0 or `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`. Value is either `0` or a combination of `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
