185 \class QIODevice -

186 \inmodule QtCore -

187 \reentrant -

188 -

189 \brief The QIODevice class is the base interface class of all I/O -

190 devices in Qt. -

191 -

192 \ingroup io -

193 -

194 QIODevice provides both a common implementation and an abstract -

195 interface for devices that support reading and writing of blocks -

196 of data, such as QFile, QBuffer and QTcpSocket. QIODevice is -

197 abstract and can not be instantiated, but it is common to use the -

198 interface it defines to provide device-independent I/O features. -

199 For example, Qt's XML classes operate on a QIODevice pointer, -

200 allowing them to be used with various devices (such as files and -

201 buffers). -

202 -

203 Before accessing the device, open() must be called to set the -

204 correct OpenMode (such as ReadOnly or ReadWrite). You can then -

205 write to the device with write() or putChar(), and read by calling -

206 either read(), readLine(), or readAll(). Call close() when you are -

207 done with the device. -

208 -

209 QIODevice distinguishes between two types of devices: -

210 random-access devices and sequential devices. -

211 -

212 \list -

213 \li Random-access devices support seeking to arbitrary -

214 positions using seek(). The current position in the file is -

215 available by calling pos(). QFile and QBuffer are examples of -

216 random-access devices. -

217 -

218 \li Sequential devices don't support seeking to arbitrary -

219 positions. The data must be read in one pass. The functions -

220 pos() and size() don't work for sequential devices. -

221 QTcpSocket and QProcess are examples of sequential devices. -

222 \endlist -

223 -

224 You can use isSequential() to determine the type of device. -

225 -

226 QIODevice emits readyRead() when new data is available for -

227 reading; for example, if new data has arrived on the network or if -

228 additional data is appended to a file that you are reading -

229 from. You can call bytesAvailable() to determine the number of -

230 bytes that are currently available for reading. It's common to use -

231 bytesAvailable() together with the readyRead() signal when -

232 programming with asynchronous devices such as QTcpSocket, where -

233 fragments of data can arrive at arbitrary points in -

234 time. QIODevice emits the bytesWritten() signal every time a -

235 payload of data has been written to the device. Use bytesToWrite() -

236 to determine the current amount of data waiting to be written. -

237 -

238 Certain subclasses of QIODevice, such as QTcpSocket and QProcess, -

239 are asynchronous. This means that I/O functions such as write() -

240 or read() always return immediately, while communication with the -

241 device itself may happen when control goes back to the event loop. -

242 QIODevice provides functions that allow you to force these -

243 operations to be performed immediately, while blocking the -

244 calling thread and without entering the event loop. This allows -

245 QIODevice subclasses to be used without an event loop, or in -

246 a separate thread: -

247 -

248 \list -

249 \li waitForReadyRead() - This function suspends operation in the -

250 calling thread until new data is available for reading. -

251 -

252 \li waitForBytesWritten() - This function suspends operation in the -

253 calling thread until one payload of data has been written to the -

254 device. -

255 -

256 \li waitFor....() - Subclasses of QIODevice implement blocking -

257 functions for device-specific operations. For example, QProcess -

258 has a function called \l {QProcess::}{waitForStarted()} which suspends operation in -

259 the calling thread until the process has started. -

260 \endlist -

261 -

262 Calling these functions from the main, GUI thread, may cause your -

263 user interface to freeze. Example: -

264 -

265 \snippet code/src_corelib_io_qiodevice.cpp 0 -

266 -

267 By subclassing QIODevice, you can provide the same interface to -

268 your own I/O devices. Subclasses of QIODevice are only required to -

269 implement the protected readData() and writeData() functions. -

270 QIODevice uses these functions to implement all its convenience -

271 functions, such as getChar(), readLine() and write(). QIODevice -

272 also handles access control for you, so you can safely assume that -

273 the device is opened in write mode if writeData() is called. -

274 -

275 Some subclasses, such as QFile and QTcpSocket, are implemented -

276 using a memory buffer for intermediate storing of data. This -

277 reduces the number of required device accessing calls, which are -

278 often very slow. Buffering makes functions like getChar() and -

279 putChar() fast, as they can operate on the memory buffer instead -

280 of directly on the device itself. Certain I/O operations, however, -

281 don't work well with a buffer. For example, if several users open -

282 the same device and read it character by character, they may end -

283 up reading the same data when they meant to read a separate chunk -

284 each. For this reason, QIODevice allows you to bypass any -

285 buffering by passing the Unbuffered flag to open(). When -

286 subclassing QIODevice, remember to bypass any buffer you may use -

287 when the device is open in Unbuffered mode. -

288 -

289 Usually, the incoming data stream from an asynchronous device is -

290 fragmented, and chunks of data can arrive at arbitrary points in time. -

291 To handle incomplete reads of data structures, use the transaction -

292 mechanism implemented by QIODevice. See startTransaction() and related -

293 functions for more details. -

294 -

295 Some sequential devices support communicating via multiple channels. These -

296 channels represent separate streams of data that have the property of -

297 independently sequenced delivery. Once the device is opened, you can -

298 determine the number of channels by calling the readChannelCount() and -

299 writeChannelCount() functions. To switch between channels, call -

300 setCurrentReadChannel() and setCurrentWriteChannel(), respectively. -

301 QIODevice also provides additional signals to handle asynchronous -

302 communication on a per-channel basis. -

303 -

307 /*! -

308 \enum QIODevice::OpenModeFlag -

309 -

310 This enum is used with open() to describe the mode in which a device -

311 is opened. It is also returned by openMode(). -

312 -

313 \value NotOpen The device is not open. -

314 \value ReadOnly The device is open for reading. -

315 \value WriteOnly The device is open for writing. Note that this mode implies -

316 Truncate. -

317 \value ReadWrite The device is open for reading and writing. -

318 \value Append The device is opened in append mode so that all data is -

319 written to the end of the file. -

320 \value Truncate If possible, the device is truncated before it is opened. -

321 All earlier contents of the device are lost. -

322 \value Text When reading, the end-of-line terminators are -

323 translated to '\\n'. When writing, the end-of-line -

324 terminators are translated to the local encoding, for -

325 example '\\r\\n' for Win32. -

326 \value Unbuffered Any buffer in the device is bypassed. -

327 -

328 Certain flags, such as \c Unbuffered and \c Truncate, are -

329 meaningless when used with some subclasses. Some of these -

330 restrictions are implied by the type of device that is represented -

331 by a subclass. In other cases, the restriction may be due to the -

332 implementation, or may be imposed by the underlying platform; for -

333 example, QTcpSocket does not support \c Unbuffered mode, and -

334 limitations in the native API prevent QFile from supporting \c -

335 Unbuffered on Windows. -

1247 This function reads a line of ASCII characters from the device, up -

1248 to a maximum of \a maxSize - 1 bytes, stores the characters in \a -

1249 data, and returns the number of bytes read. If a line could not be -

1250 read but no error ocurred, this function returns 0. If an error -

1251 occurs, this function returns the length of what could be read, or -

1252 -1 if nothing was read. -

1253 -

1254 A terminating '\\0' byte is always appended to \a data, so \a -

1255 maxSize must be larger than 1. -

1256 -

1257 Data is read until either of the following conditions are met: -

1258 -

1259 \list -

1260 \li The first '\\n' character is read. -

1261 \li \a maxSize - 1 bytes are read. -

1262 \li The end of the device data is detected. -

1263 \endlist -

1264 -

1265 For example, the following code reads a line of characters from a -

1266 file: -

1267 -

1268 \snippet code/src_corelib_io_qiodevice.cpp 2 -

1269 -

1270 The newline character ('\\n') is included in the buffer. If a -

1271 newline is not encountered before maxSize - 1 bytes are read, a -

1272 newline will not be inserted into the buffer. On windows newline -

1273 characters are replaced with '\\n'. -

1274 -

1275 This function calls readLineData(), which is implemented using -

1276 repeated calls to getChar(). You can provide a more efficient -

1277 implementation by reimplementing readLineData() in your own -

1278 subclass. -

1892 For buffered devices, this function waits until a payload of -

1893 buffered written data has been written to the device and the -

1894 bytesWritten() signal has been emitted, or until \a msecs -

1895 milliseconds have passed. If msecs is -1, this function will -

1896 not time out. For unbuffered devices, it returns immediately. -

1897 -

1898 Returns \c true if a payload of data was written to the device; -

1899 otherwise returns \c false (i.e. if the operation timed out, or if an -

1900 error occurred). -

1902 This function can operate without an event loop. It is -

1903 useful when writing non-GUI applications and when performing -

1904 I/O operations in a non-GUI thread. -
