| java.lang.Object | |
| ↳ | android.net.IpSecManager.UdpEncapsulationSocket |
This class provides access to a UDP encapsulation Socket.
UdpEncapsulationSocket wraps a system-provided datagram socket intended for IKEv2
signalling and UDP encapsulated IPsec traffic. Instances can be obtained by calling IpSecManager.openUdpEncapsulationSocket(). The provided socket cannot be re-bound by the
caller. The caller should not close the FileDescriptor returned by getFileDescriptor(), but should use close() instead.
Allowing the user to close or unbind a UDP encapsulation socket could impact the traffic
of the next user who binds to that port. To prevent this scenario, these sockets are held
open by the system so that they may only be closed by calling close() or when the user
process exits.
Summary
Public methods | |
|---|---|
void
|
close()
Close this socket. |
FileDescriptor
|
getFileDescriptor()
Get the encapsulation socket's file descriptor. |
int
|
getPort()
Get the bound port of the wrapped socket. |
String
|
toString()
Returns a string representation of the object. |
Protected methods | |
|---|---|
void
|
finalize()
Check that the socket was closed properly. |

Public methods
close
public void close ()
Close this socket.
This closes the wrapped socket. Open encapsulation sockets count against a user's
resource limits, and forgetting to close them eventually will result in ResourceUnavailableException being thrown.
| Throws | |
|---|---|
IOException |
|
getFileDescriptor
public FileDescriptor getFileDescriptor ()
Get the encapsulation socket's file descriptor.
| Returns | |
|---|---|
FileDescriptor |
|
getPort
public int getPort ()
Get the bound port of the wrapped socket.
| Returns | |
|---|---|
int |
|
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())
