Constructor & Destructor Documentation

IG.Lib.PipeServerBase.PipeServerBase ( )

inlineprivate

Prevent default constructor.

IG.Lib.PipeServerBase.PipeServerBase	(	string	pipeName,
		bool	startImmediately = `true`
	)

inline

Constructs a new pip server.

Parameters

pipeName	Name of the pipe used for client-server communication.
startImmediately	If true then server is started immediately after created.

IG.Lib.PipeServerBase.PipeServerBase	(	string	pipeName,
		string	requestEnd,
		string	responseEnd,
		string	errorBegin,
		bool	startImmediately = `true`
	)

inline

Constructs a new named pipe server with the specified pipe name and other paramters.

Parameters

pipeName	Name of the pipe.
requestEnd	Line that ends each request. If null or empty string then the requests are single line.
responseEnd	Line that ends each response. If null or empty string then the responses are single line.
errorBegin	String that begins an error response. If null or empty string then default string remains in use, i.e. IpcStreamClientServerBase2.DefaultErrorBegin
startImmediately	If true then server is started immediately after created.
