Class QIODevice.OpenModeFlag

java.lang.Object
  java.lang.Enum
      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 Summary

static QIODevice.OpenModeFlag	Append The device is opened in append mode, so that all data is written to the end of the file.
static QIODevice.OpenModeFlag	NotOpen The device is not open.
static QIODevice.OpenModeFlag	ReadOnly The device is open for reading.
static QIODevice.OpenModeFlag	ReadWrite The device is open for reading and writing.
static QIODevice.OpenModeFlag	Text When reading, the end-of-line terminators are translated to '\n'.
static QIODevice.OpenModeFlag	Truncate If possible, the device is truncated before it is opened.
static QIODevice.OpenModeFlag	Unbuffered Any buffer in the device is bypassed.
static QIODevice.OpenModeFlag	WriteOnly The device is open for writing.

Method Summary

static QIODevice.OpenMode	createQFlags(QIODevice.OpenModeFlag[] values) This function creates a com.trolltech.qt.core.QIODevice$OpenMode with the specified com.trolltech.qt.core.QIODevice$OpenModeFlag[] QIODevice$OpenModeFlag values set.
static QIODevice.OpenModeFlag	resolve(int value) Returns the QIODevice$OpenModeFlag constant with the specified int.
int	value() This function should return an integer value for the enum values of the enumeration that implements this interface.
static QIODevice.OpenModeFlag	valueOf(java.lang.String name)

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.

This function creates a com.trolltech.qt.core.QIODevice$OpenMode with the specified com.trolltech.qt.core.QIODevice$OpenModeFlag[] QIODevice$OpenModeFlag values set.

resolve

public static QIODevice.OpenModeFlag resolve(int value)

Returns the QIODevice$OpenModeFlag constant with the specified int.
