Class SocketWrapper

java.lang.Object
  org.simpleframework.transport.SocketWrapper

All Implemented Interfaces:

Socket

public class SocketWrapper
extends Object
implements Socket

This is a SocketWrapper objects that represents a TCP socket connections. This contains a map that allows attributes to be associated with the client connection. Attributes such as security certificates or other transport related details can be exposed to the Request using the socket attribute map.

This provides the connected SocketChannel that can be used to receive and response to HTTP requests. The socket channel must be selectable and in non-blocking mode. If the socket is not in a non-blocking state the connection will not be processed.

Constructor Detail

SocketWrapper

public SocketWrapper(SocketChannel channel,
                     Trace trace)

This creates a SocketWrapper from a socket channel. Any implementations of the object may use this constructor to ensure that all the data is initialized.

Parameters:

channel - the socket channel that is used as the transport

trace - used to trace specific events for the socket

SocketWrapper

public SocketWrapper(SocketChannel channel,
                     Trace trace,
                     SSLEngine engine)

This creates a SecureSocket from a socket channel. Any implementations of the object may use this constructor to ensure that all the data is initialized.

Parameters:

channel - the socket channel that is used as the transport

trace - used to trace specific events for the socket

engine - this is the SSL engine used for secure transport

Method Detail

getTrace

public Trace getTrace()

This is used to acquire the trace object that is associated with the socket. A trace object is used to collection details on what operations are being performed on the socket. For instance it may contain information relating to I/O events or more application specific events such as errors.

Specified by:

getTrace in interface Socket

Returns:

this returns the trace associated with this socket

getEngine

public SSLEngine getEngine()

This is used to acquire the SSL engine used for HTTPS. If the socket is connected to an SSL transport this returns an SSL engine which can be used to establish the secure connection and send and receive content over that connection. If this is null then the socket represents a normal transport.

Specified by:

getEngine in interface Socket

Returns:

the SSL engine used to establish a secure transport

getChannel

public SocketChannel getChannel()

This method is used to acquire the SocketChannel for the connection. This allows the server to acquire the input and output streams with which to communicate. It can also be used to configure the connection and perform various network operations that could otherwise not be performed.

Specified by:

getChannel in interface Socket

Returns:

this returns the socket used by this HTTP socket

getAttributes

public Map getAttributes()

This method is used to get the Map of attributes by this socket. The attributes map is used to maintain details about the connection. Information such as security credentials to client details can be placed within the attribute map.

Specified by:

getAttributes in interface Socket

Returns:

this returns the map of attributes for this socket
