This class was deprecated in API level 22.

Class Overview

Socket factory that implements a simple multi-home fail-over on connect failure, provided the same hostname resolves to multiple InetAddresses. Please note the connectSocket(Socket, String, int, InetAddress, int, HttpParams) method cannot be reliably interrupted by closing the socket returned by the createSocket() method.

Summary

Public Methods
Socket connectSocket(Socket sock, String host, int port, InetAddress localAddress, int localPort, HttpParams params)
Attempts to connects the socket to any of the InetAddresses the given host name resolves to.
Socket createSocket()
Creates a new, unconnected socket.
boolean equals(Object obj)
Compares this factory with an object.
static MultihomePlainSocketFactory getSocketFactory()
Gets the singleton instance of this class.
int hashCode()
Obtains a hash code for this object.
final boolean isSecure(Socket sock)
Checks whether a socket connection is secure.

Public Methods

public Socket connectSocket (Socket sock, String host, int port, InetAddress localAddress, int localPort, HttpParams params)

Added in API level 1

Attempts to connects the socket to any of the InetAddresses the given host name resolves to. If connection to all addresses fail, the last I/O exception is propagated to the caller.

Parameters
sock socket to connect to any of the given addresses
host Host name to connect to
port the port to connect to
localAddress local address
localPort local port
params HTTP parameters
Returns
  • the connected socket. The returned object may be different from the sock argument if this factory supports a layered protocol.
Throws
IOException if an error occurs during the connection
SocketTimeoutException if timeout expires before connecting

public Socket createSocket ()

Added in API level 1

Creates a new, unconnected socket. The socket should subsequently be passed to connectSocket.

Returns
  • a new socket

public boolean equals (Object obj)

Added in API level 1

Compares this factory with an object. There is only one instance of this class.

Parameters
obj the object to compare with
Returns
  • iff the argument is this object

public static MultihomePlainSocketFactory getSocketFactory ()

Added in API level 1

Gets the singleton instance of this class.

Returns
  • the one and only plain socket factory

public int hashCode ()

Added in API level 1

Obtains a hash code for this object. All instances of this class have the same hash code. There is only one instance of this class.

Returns
  • this object's hash code.

public final boolean isSecure (Socket sock)

Added in API level 1

Checks whether a socket connection is secure. This factory creates plain socket connections which are not considered secure.

Parameters
sock the connected socket
Returns
  • false
Throws
IllegalArgumentException if the argument is invalid
