Class QIODevice.OpenModeFlag

java.lang.Object
  extended by java.lang.Enum
      extended by com.trolltech.qt.core.QIODevice.OpenModeFlag
All Implemented Interfaces:
QtEnumerator, java.io.Serializable, java.lang.Comparable
Enclosing class:
QIODevice

public static final class QIODevice.OpenModeFlag
extends java.lang.Enum
implements QtEnumerator

This enum is used with open() to describe the mode in which a device is opened. It is also returned by openMode(). Certain flags, such as Unbuffered and Truncate, are meaningless when used with some subclasses. Some of these restrictions are implied by the type of device that is represented by a subclass; for example, access to a QBuffer is always unbuffered. In other cases, the restriction may be due to the implementation, or may be imposed by the underlying platform; for example, QTcpSocket does not support Unbuffered mode, and limitations in the native API prevent QFile from supporting Unbuffered on Windows.

Field Detail

NotOpen

public static final QIODevice.OpenModeFlag NotOpen
The device is not open.


ReadOnly

public static final QIODevice.OpenModeFlag ReadOnly
The device is open for reading.


WriteOnly

public static final QIODevice.OpenModeFlag WriteOnly
The device is open for writing.


ReadWrite

public static final QIODevice.OpenModeFlag ReadWrite
The device is open for reading and writing.


Append

public static final QIODevice.OpenModeFlag Append
The device is opened in append mode, so that all data is written to the end of the file.


Truncate

public static final QIODevice.OpenModeFlag Truncate
If possible, the device is truncated before it is opened. All earlier contents of the device are lost.


Text

public static final QIODevice.OpenModeFlag Text
When reading, the end-of-line terminators are translated to '\n'. When writing, the end-of-line terminators are translated to the local encoding, for example '\r\n' for Win32.


Unbuffered

public static final QIODevice.OpenModeFlag Unbuffered
Any buffer in the device is bypassed.
