Socket (gb.net)

This class implements a socket client to allow your programs to connect with socket servers. TCP and Local (Unix sockets) connections are implemented.

Vlastnosti

Host	The host to which you would like to connect.
LocalHost	Once a TCP connection is established, this property reflects local IP used by this connection.
LocalPort	Once a TCP connection is established, this property reflects local port (1-65535) used by this connection.
Path	Return or set the path of the local socket you want to connect.
Port	The port to which you would like to connect on the remote host.
RemoteHost	Once a TCP connection is established, this property reflects remote IP used by this connection.
RemotePort	Once a TCP connection is established, this property reflects remote port (1-65535) used by this connection.
Server	If that socket has been created by the Accept method of a ServerSocket, then return that ServerSocket object.
Status	Reflects the current status of a Socket object.
StatusText	Return the status of the socket as a string.
Timeout	Return or set the timeout of the socket, in milliseconds.

Blocking	Returns or sets if the stream is blocking.
ByteOrder	Returns or sets the byte order used to read or write binary data to the stream.
EndOfFile	This property signals whether the last use of LINE INPUT reached the end of file, instead of reading a full line with an end-of-line character.
EndOfLine	Return or set the newline separator used by this stream.
Eof	Return if a stream reached its end.
Handle	Returns the system file descriptor associated with this Stream.
IsTerm	Return if a stream is associated with a terminal.
Lines	Returns a virtual object that allows you to enumerate a stream line by line.
NoShare
NullTerminatedString	Return or set if strings are null-terminated when they are serialized.
Tag	Returns or sets the tag associated with the stream.
Term	Return a virtual object that allows to manage the terminal associated with the stream.

Metoda

Connect	Use this method to establish a TCP or Local (Unix) connection with a remote TCP or Local server.
Peek	This function allows you to receive data from Socket.

Begin	Start to buffer data written to the stream, so that everything will be sent when the Send method is called.
Close	Closes the stream.
Drop	Drop the data that has been buffered since the last call to the Begin method.
ReadLine	Read a line of text from the stream, like the LINE INPUT instruction.
Send	Send all the data, in one shot, since the last call to Begin.
Watch	Start or stop watching the stream file descriptor for reading or writing, after it has been opened.

Událost

Closed	This event raises after the remote side of the socket has closed the connection.
Error	This event raises when some failed (for instance remote host refused connection).
Found	When connecting using TCP sockets, first step is to translate host name to host IP. The object will raise this event when this part of the connection process has been finished
Read	This event raises when data arrives to the socket from the other side of connection.
Ready	This event raises after a connection has been established successfully.
Write	This event is raised when the internal socket send buffers can take in more data.

This class performs its work asynchronously, so the program will not be stopped while connecting, sending or receiving data.

This class is derived from the class Stream, so you can use standard Stream & Input/Output functions to send and receive data, and to close the socket.

Sockets can be used if the library "gb.net" is included in the project. To include this library use the menu [Project] [Properties] [Components] and tick the component "gb.net".
