[править] Подробное описание

The QUrlInfo class stores information about URLs.

The information about a URL that can be retrieved includes name(), permissions(), owner(), group(), size(), lastModified(), lastRead(), isDir(), isFile(), isSymLink(), isWritable(), isReadable() and isExecutable().

You can create your own QUrlInfo objects passing in all the relevant information in the constructor, and you can modify a QUrlInfo; for each getter mentioned above there is an equivalent setter. Note that setting values does not affect the underlying resource that the QUrlInfo provides information about; for example if you call setWritable(true) on a read-only resource the only thing changed is the QUrlInfo object, not the resource.

[править] Описание типов

[править]
enum QUrlInfo::PermissionSpec

This enum is used by the permissions() function to report the permissions of a file.

Константа	Значение	Описание
`QUrlInfo::ReadOwner`	`00400`	The file is readable by the owner of the file.
`QUrlInfo::WriteOwner`	`00200`	The file is writable by the owner of the file.
`QUrlInfo::ExeOwner`	`00100`	The file is executable by the owner of the file.
`QUrlInfo::ReadGroup`	`00040`	The file is readable by the group.
`QUrlInfo::WriteGroup`	`00020`	The file is writable by the group.
`QUrlInfo::ExeGroup`	`00010`	The file is executable by the group.
`QUrlInfo::ReadOther`	`00004`	The file is readable by anyone.
`QUrlInfo::WriteOther`	`00002`	The file is writable by anyone.
`QUrlInfo::ExeOther`	`00001`	The file is executable by anyone.

QUrlInfo::QUrlInfo ()

Constructs an invalid QUrlInfo object with default values.

[править]
QUrlInfo::QUrlInfo ( const QUrlInfo & ui )

Copy constructor, copies ui to this URL info object.

[править]
QUrlInfo::QUrlInfo ( const QString & name, int permissions, const QString & owner, const QString & group, qint64 size, const QDateTime & lastModified, const QDateTime & lastRead, bool isDir, bool isFile, bool isSymLink, bool isWritable, bool isReadable, bool isExecutable )

Constructs a QUrlInfo object by specifying all the URL's information.

The information that is passed is the name, file permissions, owner and group and the file's size. Also passed is the lastModified date/time and the lastRead date/time. Flags are also passed, specifically, isDir, isFile, isSymLink, isWritable, isReadable and isExecutable.

The information that is passed is the url, file permissions, owner and group and the file's size. Also passed is the lastModified date/time and the lastRead date/time. Flags are also passed, specifically, isDir, isFile, isSymLink, isWritable, isReadable and isExecutable.

[править]
QUrlInfo::~QUrlInfo () `[virtual]`

Destroys the URL info object.

[править]
bool QUrlInfo::equal ( const QUrlInfo & i1, const QUrlInfo & i2, int sortBy ) `[static]`

Returns true if i1 equals to i2; otherwise returns false. The objects are compared by the value, which is specified by sortBy. This must be one of QDir::Name, QDir::Time or QDir::Size.

[править]
bool QUrlInfo::greaterThan ( const QUrlInfo & i1, const QUrlInfo & i2, int sortBy ) `[static]`

Returns true if i1 is greater than i2; otherwise returns false. The objects are compared by the value, which is specified by sortBy. This must be one of QDir::Name, QDir::Time or QDir::Size.

[править]
QString QUrlInfo::group () const

Returns the group of the URL.

[править]
bool QUrlInfo::isDir () const

Returns true if the URL is a directory; otherwise returns false.

Смотрите также isValid().

[править]
bool QUrlInfo::isExecutable () const

Returns true if the URL is executable; otherwise returns false.

Смотрите также isValid().

[править]
bool QUrlInfo::isFile () const

Returns true if the URL is a file; otherwise returns false.

Смотрите также isValid().

[править]
bool QUrlInfo::isReadable () const

Returns true if the URL is readable; otherwise returns false.

Смотрите также isValid().

[править]
bool QUrlInfo::isSymLink () const

Returns true if the URL is a symbolic link; otherwise returns false.

Смотрите также isValid().

[править]
bool QUrlInfo::isValid () const

Returns true if the URL info is valid; otherwise returns false. Valid means that the QUrlInfo contains real information.

You should always check if the URL info is valid before relying on the values.

[править]
bool QUrlInfo::isWritable () const

Returns true if the URL is writable; otherwise returns false.

Смотрите также isValid().

[править]
QDateTime QUrlInfo::lastModified () const

Returns the last modification date of the URL.

See also setLastModified() and isValid().

[править]
QDateTime QUrlInfo::lastRead () const

Returns the date when the URL was last read.

Смотрите также isValid().

[править]
bool QUrlInfo::lessThan ( const QUrlInfo & i1, const QUrlInfo & i2, int sortBy ) `[static]`

Returns true if i1 is less than i2; otherwise returns false. The objects are compared by the value, which is specified by sortBy. This must be one of QDir::Name, QDir::Time or QDir::Size.

[править]
QString QUrlInfo::name () const

Returns the file name of the URL.

[править]
QString QUrlInfo::owner () const

Returns the owner of the URL.

[править]
int QUrlInfo::permissions () const

Returns the permissions of the URL. You can use the PermissionSpec flags to test for certain permissions.

See also setPermissions() and isValid().

[править]
void QUrlInfo::setDir ( bool b ) `[virtual]`

If b is true then the URL is set to be a directory; if b is false then the URL is set not to be a directory (which normally means it is a file). (Note that a URL can refer to both a file and a directory even though most file systems do not support this.)
