Created:Tue Nov 25 09:13:36 EST 2014
/* Corresponds to the socket's LOCAL-HOST attribute




Method Summary
Options Name Purpose
Connect () /** Connect to the server specified, based on existing ConnectionParameters */
Connect (ClientSocketConnectionParameters) /** Connect to the server specified, based on passed-in Connection Parameters @param ClientSocketConnectionParameters Connection information for the connection. */
Connect (URI) /** Connect to the server specified, based on passed-in URI @param URI Connection information for the connection. */
CreateServer () /** Creates a server object (ie this-object:Server). This is separated from the Connect/Disconnect pair of methods so that one server can be connected and disconnected multiple time. */
DestroyServer () /** Destroys the server object (ie this-object:Server). This is separated from the Connect/Disconnect pair of methods so that one server can be connected and disconnected multiple time. */
Disconnect () /** Disconnect from the server, if connected */
LOGICAL IsConnected () /* Indicated whether we have a connection @return logical TRUE is the socket is connected; false otherwise */
OnDataReceived (SocketReadEventArgs) /** Publishes the DataReceived event. @param SocketReadEventArgs Arguments for this event */
OnReadTerminated (SocketReadEventArgs) /** Publishes the ReadTerminated event. @param EventArgs Arguments for this event */
OnReadTimeout (SocketReadEventArgs) /** Publishes the ReadTimeout event. @param EventArgs Arguments for this event */
ReadResponseHandler () /** Callback/event procedure fired on the READ-RESPONSE event of the socket. */
SetSocketOptions (handle) /* Sets the various socket options, per this object's properties. @param handle The socket on which to set these options */
StartTls (character) /* Starts a new TLS (for insecure connections), or changes (for already-secure) connections, the certificates used to decrypt the traffic. Used primarily for HTTP proxy tunnelling. @param character The certificate subject (host) name */
WaitForResponse () /** Waits for a response from a write event on the socket with a no timeout. Uses the default timeout, which is none/zero */
WaitForResponse (decimal) /** Waits for a response from a write event on the socket. Polls (ie loops) for a response @param decimal A timeout value for read events in seconds. A zero value means no timeout. */
WaitForResponseAsync (decimal) /** Waits for a response from a write event on the socket. Uses a WAIT-FOR loop to emulate/provide async. @param decimal A timeout value for read events in seconds. A zero value means no timeout. */
WriteData (Memptr) /** Writes data to the connected server. @param Memptr The data to be written to the socket. */

Constructor Summary
Options Name Purpose
ClientSocket () /** Default constructor. Connection parameters can be specified via the Connnect() method. */
ClientSocket (ClientSocketConnectionParameters) /** Constructor. @param ClientSocketConnectionParameters A URI and other parameters that this socket will connect to. */

Event Summary
Options Name Purpose
DataReceived (ClientSocket, SocketReadEventArgs) /** Event fired when a chunk of data is received from the socket */
ReadTerminated (ClientSocket, SocketReadEventArgs) /** Fired when a read is terminated for an reason (socket disconnect, no data etc) */
ReadTimeout (ClientSocket, SocketReadEventArgs) /** Fired when a read times out (optional based on a timeout) */

Method Detail
Top

Connect ()
Purpose: Connect to the server specified, based on existing ConnectionParameters
Top

Connect (ClientSocketConnectionParameters)
Purpose: Connect to the server specified, based on passed-in Connection Parameters
Parameters:
poParams OpenEdge.Net.ServerConnection.ClientSocketConnectionParameters
Top

Connect (URI)
Purpose: Connect to the server specified, based on passed-in URI
Parameters:
poURI OpenEdge.Net.URI
Top

CreateServer ()
Purpose: Creates a server object (ie this-object:Server). This is separated
from the Connect/Disconnect pair of methods so that one server can
be connected and disconnected multiple time.
Top

DestroyServer ()
Purpose: Destroys the server object (ie this-object:Server). This is separated
from the Connect/Disconnect pair of methods so that one server can
be connected and disconnected multiple time.
Top

Disconnect ()
Purpose: Disconnect from the server, if connected
Top

LOGICAL IsConnected ()
/* Indicated whether we have a connection
Returns LOGICAL
logical TRUE is the socket is connected; false otherwise
Top

OnDataReceived (SocketReadEventArgs)
Purpose: Publishes the DataReceived event.
Parameters:
poEventArgs OpenEdge.Net.ServerConnection.SocketReadEventArgs
Top

OnReadTerminated (SocketReadEventArgs)
Purpose: Publishes the ReadTerminated event.
Parameters:
poEventArgs OpenEdge.Net.ServerConnection.SocketReadEventArgs
Top

OnReadTimeout (SocketReadEventArgs)
Purpose: Publishes the ReadTimeout event.
Parameters:
poEventArgs OpenEdge.Net.ServerConnection.SocketReadEventArgs
Top

ReadResponseHandler ()
Purpose: Callback/event procedure fired on the READ-RESPONSE event of the
socket.
Top

SetSocketOptions (handle)
/* Sets the various socket options, per this object's properties.
Parameters:
phSocket HANDLE
Top

StartTls (character)
/* Starts a new TLS (for insecure connections), or changes (for already-secure)
connections, the certificates used to decrypt the traffic. Used primarily
for HTTP proxy tunnelling.
Parameters:
pCertificatSubjectName CHARACTER
Top

WaitForResponse ()
Purpose: Waits for a response from a write event on the socket with a
no timeout. Uses the default timeout, which is none/zero
Top

WaitForResponse (decimal)
Purpose: Waits for a response from a write event on the socket. Polls
(ie loops) for a response
value means no timeout.
Parameters:
pdTimeout DECIMAL
Top

WaitForResponseAsync (decimal)
Purpose: Waits for a response from a write event on the socket. Uses a WAIT-FOR loop
to emulate/provide async.
value means no timeout.
Parameters:
pdTimeout DECIMAL
Top

WriteData (Memptr)
Purpose: Writes data to the connected server.
Parameters:
poData OpenEdge.Core.Memptr
