org.apache.http.conn.MultihomePlainSocketFactory

java.lang.Object
org.apache.http.conn.MultihomePlainSocketFactory SocketFactory

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.

Details

Public Methods

public 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. 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

Throws

IOException if an error occurs during the connection
SocketTimeoutException if timeout expires before connecting

public Socket createSocket()

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

public boolean equals(Object obj)

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()

Gets the singleton instance of this class.

Returns

  • the one and only plain socket factory

public int hashCode()

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

  • int the receiver's hash.

public final boolean isSecure(Socket sock)

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
