## Detailed Description

The QUrlInfo class stores information about URLs.

This class is just a container for storing information about URLs, which is why all information must be passed in the constructor.

Unless you're reimplementing a network protocol you're unlikely to create QUrlInfo objects yourself, but you may get QUrlInfo objects from functions, e.g. QUrlOperator::info().

See also Input/Output and Networking and Miscellaneous Classes.

## Member Function Documentation

### QUrlInfo::QUrlInfo ()

Constructs an invalid QUrlInfo object with default values.

See also isValid().

### QUrlInfo::QUrlInfo ( const QUrlOperator & path, const QString & file )

Constructs a QUrlInfo object with information about the file file in the path. It tries to find the information about the file in the QUrlOperator path.

If the information is not found, this constructor creates an invalid QUrlInfo, i.e. isValid() returns FALSE. You should always check if the URL info is valid before relying on the return values of any getter functions.

If file is empty, it defaults to the actual directory of the QUrlOperator path.

See also isValid() and QUrlOperator::info().

### QUrlInfo::QUrlInfo ( const QUrlInfo & ui )

Copy constructor, copies ui to this URL info object.

### QUrlInfo::QUrlInfo ( const QString & name, int permissions, const QString & owner, const QString & group, uint 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, the permissions, the owner and group, as well as the size, lastModified date/time and lastRead date/time. Flags are also passed, specifically, isDir, isFile, isSymLink, isWritable, isReadable and isExecutable.

### QUrlInfo::QUrlInfo ( const QUrl & url, int permissions, const QString & owner, const QString & group, uint 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 url, the permissions, the owner and group, as well as the size, lastModified date/time and lastRead date/time. Flags are also passed, specifically, isDir, isFile, isSymLink, isWritable, isReadable and isExecutable.

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

Destroys the URL ifno object. The QUrlOperator object to which this URL referred is not affected.

### 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.

### 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.

### QString QUrlInfo::group () const

Returns the group of the URL.

See also isValid().

### bool QUrlInfo::isDir () const

Returns TRUE if the URL is a directory; otherwise returns FALSE.

See also isValid().

Example: network/networkprotocol/nntp.cpp.

### bool QUrlInfo::isExecutable () const

Returns TRUE if the URL is executable; otherwise returns FALSE.

See also isValid().

### bool QUrlInfo::isFile () const

Returns TRUE if the URL is a file; otherwise returns FALSE.

See also isValid().

### bool QUrlInfo::isReadable () const

Returns TRUE if the URL is readable; otherwise returns FALSE.

See also isValid().

### bool QUrlInfo::isSymLink () const

Returns TRUE if the URL is a symbolic link; otherwise returns FALSE.

See also isValid().

### bool QUrlInfo::isValid () const

Returns TRUE if the URL info is valid; otherwise returns FALSE. Valid means that the QUrlInfo contains real information. E.g., a call to QUrlOperator::info() might return a an invalid QUrlInfo, if no information about the requested entry is available.

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

### bool QUrlInfo::isWritable () const

Returns TRUE if the URL is writable; otherwise returns FALSE.

See also isValid().

### QDateTime QUrlInfo::lastModified () const

Returns the last modification date of the URL.

See also isValid().

### QDateTime QUrlInfo::lastRead () const

Returns the date when the URL was read the last time.

See also isValid().

### 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.

### QString QUrlInfo::name () const

Returns the file name of the URL.

See also isValid().

Examples: network/ftpclient/ftpmainwindow.cpp and network/ftpclient/ftpview.cpp.

### QUrlInfo & QUrlInfo::operator= ( const QUrlInfo & ui )

Assigns the values of ui to this QUrlInfo object.

### bool QUrlInfo::operator== ( const QUrlInfo & i ) const

Compares this QUrlInfo with i and returns TRUE if they are equal; otherwise returns FALSE.

### QString QUrlInfo::owner () const

Returns the owner of the URL.

See also isValid().

### int QUrlInfo::permissions () const

Returns the permissions of the URL.

See also isValid().

### 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 both a file and a directory even though most file systems do not support this duality.)

If you call this function for an invalid URL info, this function turns it into a valid one.

See also isValid().

Example: network/networkprotocol/nntp.cpp.

### void QUrlInfo::setFile ( bool b )`[virtual]`

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

If you call this function for an invalid URL info, this function turns it into a valid one.

See also isValid().

Example: network/networkprotocol/nntp.cpp.

### void QUrlInfo::setGroup ( const QString & s )`[virtual]`

Specifies that the owning group of the URL is called s.

If you call this function for an invalid URL info, this function turns it into a valid one.

See also isValid().

### void QUrlInfo::setLastModified ( const QDateTime & dt )`[virtual]`

Specifies that the object the URL refers to was last modified at dt.

If you call this function for an invalid URL info, this function turns it into a valid one.

See also isValid().

### void QUrlInfo::setName ( const QString & name )`[virtual]`

Sets the name of the URL to name. The name is the full text, for example, "http://doc.trolltech.com/qurlinfo.html".

If you call this function for an invalid URL info, this function turns it into a valid one.

See also isValid().

Example: network/networkprotocol/nntp.cpp.

### void QUrlInfo::setOwner ( const QString & s )`[virtual]`

Specifies that the owner of the URL is called s.

If you call this function for an invalid URL info, this function turns it into a valid one.

See also isValid().

### void QUrlInfo::setPermissions ( int p )`[virtual]`

Specifies that the URL has access permision p.

If you call this function for an invalid URL info, this function turns it into a valid one.

See also isValid().

### void QUrlInfo::setReadable ( bool b )`[virtual]`

Specifies that the URL is readable if b is TRUE and not readable if b is FALSE.

If you call this function for an invalid URL info, this function turns it into a valid one.

See also isValid().

Example: network/networkprotocol/nntp.cpp.

### void QUrlInfo::setSize ( uint s )`[virtual]`

Specifies that the URL has size s.

If you call this function for an invalid URL info, this function turns it into a valid one.

See also isValid().

### void QUrlInfo::setSymLink ( bool b )`[virtual]`

Specifies that the URL refers to a symbolic link if b is TRUE and that it does not if b is FALSE.
