Enum QIODevice.OpenModeFlag

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

public static enum QIODevice.OpenModeFlag
extends java.lang.Enum<QIODevice.OpenModeFlag>
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.


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

Enum Constant 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.

Method Detail

values

public static final QIODevice.OpenModeFlag[] values()
Returns an array containing the constants of this enum type, in the order they're declared. This method may be used to iterate over the constants as follows:
for(QIODevice.OpenModeFlag c : QIODevice.OpenModeFlag.values())
        System.out.println(c);

Returns:
an array containing the constants of this enum type, in the order they're declared

valueOf

public static QIODevice.OpenModeFlag valueOf(java.lang.String name)
Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:
name - the name of the enum constant to be returned.
Returns:
the enum constant with the specified name
Throws:
java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

value

public int value()
Description copied from interface: QtEnumerator
This function should return an integer value for the enum values of the enumeration that implements this interface.

Specified by:
value in interface QtEnumerator

createQFlags

public static QIODevice.OpenMode createQFlags(QIODevice.OpenModeFlag... values)

resolve

public static QIODevice.OpenModeFlag resolve(int value)
