name="details"></a><h2>Detailed Description</h2> - - -The TQValueList class is a value-based template class that -provides lists. -<p> - - - - -<p> TQValueList is a TQt implementation of an STL-like list container. -It can be used in your application if the standard <tt>list</tt> is not -available for your target platform(s). TQValueList is part of the -<a href="qtl.html">TQt Template Library</a>. -<p> TQValueList<T> defines a template instance to create a list of -values that all have the class T. Note that TQValueList does not -store pointers to the members of the list; it holds a copy of -every member. This is why these kinds of classes are called "value -based"; <a href="qptrlist.html">TQPtrList</a> and <a href="qdict.html">TQDict</a> are "pointer based". -<p> TQValueList contains and manages a collection of objects of type T -and provides iterators that allow the contained objects to be -addressed. TQValueList owns the contained items. For more relaxed -ownership semantics, see <a href="qptrcollection.html">TQPtrCollection</a> and friends which are -pointer-based containers. -<p> Some classes cannot be used within a TQValueList, for example, all -classes derived from <a href="qobject.html">TQObject</a> and thus all classes that implement -widgets. Only values can be used in a TQValueList. To qualify as a -value the class must provide: -<ul> -<li> a copy constructor; -<li> an assignment operator; -<li> a default constructor, i.e. a constructor that does not take any arguments. -</ul> -<p> Note that C++ defaults to field-by-field assignment operators and -copy constructors if no explicit version is supplied. In many -cases this is sufficient. -<p> In addition, some compilers (e.g. Sun CC) might require that the -class provides an equality operator (<a href="#operator-eq-eq">operator==</a>()). -<p> TQValueList's function naming is consistent with the other TQt -classes (e.g. <a href="#count">count</a>(), <a href="#isEmpty">isEmpty</a>()). TQValueList also provides extra -functions for compatibility with STL algorithms, such as <a href="#size">size</a>() -and <a href="#empty">empty</a>(). Programmers already familiar with the STL <tt>list</tt> may -prefer to use the STL-compatible functions. -<p> Example: -<pre> - class Employee - { - public: - Employee(): sn(0) {} - Employee( const <a href="qstring.html">TQString</a>& forename, const <a href="qstring.html">TQString</a>& surname, int salary ) - : fn(forename), sn(surname), sal(salary) - {} - - <a href="qstring.html">TQString</a> forename() const { return fn; } - <a href="qstring.html">TQString</a> surname() const { return sn; } - int salary() const { return sal; } - void setSalary( int salary ) { sal = salary; } - - private: - <a href="qstring.html">TQString</a> fn; - <a href="qstring.html">TQString</a> sn; - int sal; - }; - - typedef TQValueList<Employee> EmployeeList; - EmployeeList list; - - list.append( Employee("John", "Doe", 50000) ); - list.append( Employee("Jane", "Williams", 80000) ); - list.append( Employee("Tom", "Jones", 60000) ); - - Employee mary( "Mary", "Hawthorne", 90000 ); - list.append( mary ); - mary.setSalary( 100000 ); - - EmployeeList::<a href="#iterator">iterator</a> it; - for ( it = list.begin(); it != list.end(); ++it ) - cout << (*it).surname().latin1() << ", " << - (*it).forename().latin1() << " earns " << - (*it).salary() << endl; - - // Output: - // Doe, John earns 50000 - // Williams, Jane earns 80000 - // Hawthorne, Mary earns 90000 - // Jones, Tom earns 60000 - </pre> - -<p> Notice that the latest changes to Mary's salary did not affect the -value in the list because the list created a copy of Mary's entry. -<p> There are several ways to find items in the list. The <a href="#begin">begin</a>() and -<a href="#end">end</a>() functions return iterators to the beginning and end of the -list. The advantage of getting an iterator is that you can move -forward or backward from this position by -incrementing/decrementing the iterator. The iterator returned by -end() points to the item which is one <em>past</em> the last item in the -container. The past-the-end iterator is still associated with the -list it belongs to, however it is <em>not</em> dereferenceable; -<a href="qsize.html#operator*-4">operator*</a>() will not return a well-defined value. If the list is -<a href="#empty">empty</a>(), the iterator returned by begin() will equal the iterator -returned by end(). -<p> Another way to find an item in the list is by using the <a href="qtl.html#qFind">qFind()</a> algorithm. For example: -<p> <pre> - TQValueList<int> list; - ... - TQValueList<int>::<a href="#iterator">iterator</a> it = qFind( list.<a href="#begin">begin</a>(), list.<a href="#end">end</a>(), 3 ); - if ( it != list.<a href="#end">end</a>() ) - // it points to the found item - </pre> - -<p> It is safe to have multiple iterators a the list at the same -time. If some member of the list is removed, only iterators -pointing to the removed member become invalid. Inserting into the -list does not invalidate any iterator. For convenience, the -function <a href="#last">last</a>() returns a reference to the last item in the list, -and <a href="#first">first</a>() returns a reference to the the first item. If the -list is empty(), both last() and first() have undefined behavior -(your application will crash or do unpredictable things). Use -last() and first() with caution, for example: -<p> <pre> - TQValueList<int> list; - list.<a href="#append">append</a>( 1 ); - list.<a href="#append">append</a>( 2 ); - list.<a href="#append">append</a>( 3 ); - ... - if ( !list.<a href="#empty">empty</a>() ) { - // OK, modify the first item - int& i = list.<a href="#first">first</a>(); - i = 18; - } - ... - TQValueList<double> dlist; - double d = dlist.<a href="#last">last</a>(); // undefined - </pre> - -<p> Because TQValueList is value-based there is no need to be careful -about deleting items in the list. The list holds its own copies -and will free them if the corresponding member or the list itself -is deleted. You can force the list to free all of its items with -<a href="#clear">clear</a>(). -<p> TQValueList is <a href="shclass.html#shared-implicitly">shared implicitly</a>, which means it can be copied in -constant time, i.e. O(1). If multiple TQValueList instances share -the same data and one needs to modify its contents, this modifying -instance makes a copy and modifies its private copy; therefore it -does not affect the other instances; this takes O(n) time. This is -often called "copy on write". If a TQValueList is being used in a -multi-threaded program, you must protect all access to the list. -See <a href="qmutex.html">TQMutex</a>. -<p> There are several ways to insert items into the list. The -<a href="#prepend">prepend</a>() and <a href="#append">append</a>() functions insert items at the beginning and -the end of the list respectively. The <a href="#insert">insert</a>() function comes in -several flavors and can be used to add one or more items at -specific positions within the list. -<p> Items can also be removed from the list in several ways. There -are several variants of the <a href="#remove">remove</a>() function, which removes a -specific item from the list. The remove() function will find and -remove items according to a specific item value. -<p> Lists can also be sorted using the <a href="qtl.html">TQt Template - Library</a>. For example with qHeapSort(): -<p> Example: -<pre> - TQValueList<int> list; - list.<a href="#append">append</a>( 5 ); - list.<a href="#append">append</a>( 8 ); - list.<a href="#append">append</a>( 3 ); - list.<a href="#append">append</a>( 4 ); - qHeapSort( list ); - </pre> - -<p> <p>See also <a href="qvaluelistiterator.html">TQValueListIterator</a>, <a href="qtl.html">TQt Template Library Classes</a>, <a href="shared.html">Implicitly and Explicitly Shared Classes</a>, and <a href="tools.html">Non-GUI Classes</a>. - -<hr><h2>Member Type Documentation</h2> -<h3 class=fn><a name="ConstIterator"></a>TQValueList::ConstIterator</h3> - -<p> This iterator is an instantiation of <a href="qvaluelistconstiterator.html">TQValueListConstIterator</a> for -the same type as this TQValueList.
