|
|
|
|
|
|
The TQValueListConstIterator class provides a const iterator
|
|
for <a href="ntqvaluelist.html">TQValueList</a>.
|
|
<p>
|
|
|
|
|
|
<p> In contrast to <a href="qvaluelistiterator.html">TQValueListIterator</a>, this class is used to iterate
|
|
over a const list. It does not allow modification of the values of
|
|
the list since that would break const semantics.
|
|
<p> You can create the appropriate const iterator type by using the <tt>const_iterator</tt> typedef provided by TQValueList.
|
|
<p> For more information on TQValueList iterators, see
|
|
TQValueListIterator.
|
|
<p> <p>See also <a href="qvaluelistiterator.html">TQValueListIterator</a>, <a href="ntqvaluelist.html">TQValueList</a>, <a href="ntqtl.html">TQt Template Library Classes</a>, and <a href="tools.html">Non-GUI Classes</a>.

Reference to value_type.

|
|
<h3 class=fn><a name="TQValueListConstIterator"></a>TQValueListConstIterator::TQValueListConstIterator ()
|
|
</h3>
|
|
|
|
<p> Creates un uninitialized iterator.
|
|
|
|
<h3 class=fn><a name="TQValueListConstIterator-3"></a>TQValueListConstIterator::TQValueListConstIterator ( const <a href="qvaluelistconstiterator.html">TQValueListConstIterator</a><T> & it )
|
|
</h3>
|
|
|
|
<p> This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
|
|
<p> Constructs a copy of the iterator <em>it</em>.
|
|
|
|
<h3 class=fn><a name="TQValueListConstIterator-4"></a>TQValueListConstIterator::TQValueListConstIterator ( const <a href="qvaluelistiterator.html">TQValueListIterator</a><T> & it )
|
|
</h3>
|
|
|
|
<p> Constructs a copy of the iterator <em>it</em>.
|
|
|
|
<h3 class=fn>bool <a name="operator!-eq"></a>TQValueListConstIterator::operator!= ( const <a href="qvaluelistconstiterator.html">TQValueListConstIterator</a><T> & it ) const
|
|
</h3>
|
|
|
|
<p> Compares this iterator with <em>it</em> and returns TRUE if they point
|
|
to different items; otherwise returns FALSE.
|
|
|
|
<h3 class=fn>const T & <a name="operator*"></a>TQValueListConstIterator::operator* () const
|
|
</h3>
|
|
|
|
<p> Asterisk operator. Returns a reference to the current iterator item.
|
|
|
|
<h3 class=fn><a href="qvaluelistconstiterator.html">TQValueListConstIterator</a><T> & <a name="operator++"></a>TQValueListConstIterator::operator++ ()
|
|
</h3>
|
|
|
|
<p> Prefix ++ makes the succeeding item current and returns an
|
|
iterator pointing to the new current item. The iterator cannot
|
|
check whether it reached the end of the list. Incrementing the
|
|
iterator returned by end() causes undefined results.
|
|
|
|
<h3 class=fn><a href="qvaluelistconstiterator.html">TQValueListConstIterator</a><T> <a name="operator++-2"></a>TQValueListConstIterator::operator++ ( int )
|
|
</h3>
|
|
|
|
<p> This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
|
|
<p> Postfix ++ makes the succeeding item current and returns an
|
|
iterator pointing to the new current item. The iterator cannot
|
|
check whether it reached the end of the list. Incrementing the
|
|
iterator returned by end() causes undefined results.
|
|
|
|
<h3 class=fn><a href="qvaluelistconstiterator.html">TQValueListConstIterator</a><T> & <a name="operator--"></a>TQValueListConstIterator::operator-- ()
|
|
</h3>
|
|
|
|
<p> Prefix -- makes the previous item current and returns an iterator
|
|
pointing to the new current item. The iterator cannot check
|
|
whether it reached the beginning of the list. Decrementing the
|
|
iterator returned by begin() causes undefined results.
|
|
|
|
<h3 class=fn><a href="qvaluelistconstiterator.html">TQValueListConstIterator</a><T> <a name="operator---2"></a>TQValueListConstIterator::operator-- ( int )

|
|
|
|
<p> Compares this iterator with <em>it</em> and returns TRUE if they point

to the same item; otherwise returns FALSE.
