	`destructor Destroy(); override;`

	`function open(): bool;`
Opens client or server.

function doYourJob(addr: PSockAddrIn; buf: pointer; dataLen: int): bool; virtual; abstract;

Processes any pending job.

buf: ponter to data buffer
dataLen: size of data in buffer. Could be 0, which means no data was read in last cycle

True if some job was done, or False if there was nothing to do

	`function execute(threadID: unsigned): int; override;`

function readData(buf: pointer; maxSize: int; out addr: sockaddr_in): int; virtual; abstract;

Reads data from internal or exteranal socket(s) Client and server will do it differently.

Size of data actually read

	`procedure close();`
Closes client or server.

	`procedure doOpen(); virtual;`
Prepare for open.

	`procedure startIn(); override;`
Prepares socket

	`property active: bool read f_active;`
True if server or client is active.

	`property port: string read f_port;`
Local server port for STUN Server Remote server port for STUN Client

	`property proto: int read f_proto;`
Internal socket proto

	`property socketError: int read f_socketError;`
Fatal socket error or 0 if no error.
