|
|
|
|
|
|
The TQUrlInfo class stores information about URLs.
|
|
<p>
|
|
|
|
<p> This class is just a container for storing information about URLs,
|
|
which is why all information must be passed in the constructor.
|
|
<p> Unless you're reimplementing a network protocol you're unlikely to
|
|
create TQUrlInfo objects yourself, but you may receive TQUrlInfo
|
|
objects from functions, e.g. <a href="ntqurloperator.html#info">TQUrlOperator::info</a>().
|
|
<p> The information that can be retrieved includes <a href="#name">name</a>(),
|
|
<a href="#permissions">permissions</a>(), <a href="#owner">owner</a>(), <a href="#group">group</a>(), <a href="#size">size</a>(), <a href="#lastModified">lastModified</a>(),
|
|
<a href="#lastRead">lastRead</a>(), <a href="#isDir">isDir</a>(), <a href="#isFile">isFile</a>(), <a href="#isSymLink">isSymLink</a>(), <a href="#isWritable">isWritable</a>(),
|
|
<a href="#isReadable">isReadable</a>() and <a href="#isExecutable">isExecutable</a>().

<h3 class=fn><a name="PermissionSpec-enum"></a>TQUrlInfo::PermissionSpec</h3>
|
|
|
|
<p> This enum is used by the <a href="#permissions">permissions</a>() function to report the
|
|
permissions of a file.
|
|
<ul>
|
|
<li><tt>TQUrlInfo::ReadOwner</tt> - The file is readable by the owner of the file.
|
|
<li><tt>TQUrlInfo::WriteOwner</tt> - The file is writable by the owner of the file.
|
|
<li><tt>TQUrlInfo::ExeOwner</tt> - The file is executable by the owner of the file.

<li><tt>TQUrlInfo::ReadGroup</tt> - The file is readable by the group.
|

<li><tt>TQUrlInfo::WriteGroup</tt> - The file is writable by the group.

<h3 class=fn><a name="TQUrlInfo"></a>TQUrlInfo::TQUrlInfo ()
|
|
</h3>
|
|
Constructs an invalid TQUrlInfo object with default values.
|
|
<p> <p>See also <a href="#isValid">isValid</a>().
|
|
|
|
<h3 class=fn><a name="TQUrlInfo-2"></a>TQUrlInfo::TQUrlInfo ( const <a href="ntqurloperator.html">TQUrlOperator</a> & path, const <a href="tqstring.html">TQString</a> & file )
|
|
</h3>
|
|
Constructs a TQUrlInfo object with information about the file <em>file</em> in the <em>path</em>. It tries to find the information about the <em>file</em> in the <a href="ntqurloperator.html">TQUrlOperator</a> <em>path</em>.
|
|
<p> If the information is not found, this constructor creates an
|
|
invalid TQUrlInfo, i.e. <a href="#isValid">isValid</a>() returns FALSE. You should always
|
|
check if the URL info is valid before relying on the return values
|
|
of any getter functions.
|
|
<p> If <em>file</em> is empty, it defaults to the TQUrlOperator <em>path</em>, i.e.
|
|
to the directory.
|
|
<p> <p>See also <a href="#isValid">isValid</a>() and <a href="ntqurloperator.html#info">TQUrlOperator::info</a>().
