151

<h3 class="fn"><a name="Q3ValueVector"></a>Q3ValueVector::Q3ValueVector ()</h3>

149

152

<p>Constructs an empty vector without any elements. To create a vector which reserves an initial amount of space for elements, use <tt>Q3ValueVector(size_type n)</tt>.</p>

150

153

<h3 class="fn"><a name="Q3ValueVector-2"></a>Q3ValueVector::Q3ValueVector ( const Q3ValueVector<T> & <i>v</i> )</h3>

151

154

<p>Constructs a copy of <i>v</i>.</p>

152

<p>This operation costs O(1) time because <a href="q3valuevector.html">Q3ValueVector</a> is implicitly shared.</p>

155

<p>This operation costs O(1) time because <a href="q3valuevector.html" class="compat">Q3ValueVector</a> is implicitly shared.</p>

153

156

<p>The first modification to the vector does takes O(n) time, because the elements must be copied.</p>

154

157

<h3 class="fn"><a name="Q3ValueVector-3"></a>Q3ValueVector::Q3ValueVector ( <a href="qvector.html">QVector</a><T>::size_type <i>n</i>, const T & <i>val</i> = T() )</h3>

155

158

<p>Constructs a vector with an initial size of <i>n</i> elements. Each element is initialized with the value of <i>val</i>.</p>

156

159

<h3 class="fn"><a name="Q3ValueVector-4"></a>Q3ValueVector::Q3ValueVector ( const std::vector<T> & <i>v</i> )</h3>

157

160

<p>This operation costs O(n) time because <i>v</i> is copied.</p>

161

158

162

<h3 class="fn"><a name="at"></a>T & Q3ValueVector::at ( int <i>i</i>, bool * <i>ok</i> = 0 )</h3>

159

163

<p>Returns a reference to the element with index <i>i</i>. If <i>ok</i> is non-null, and the index <i>i</i> is out of range, *<i>ok</i> is set to FALSE and the returned reference is undefined. If the index <i>i</i> is within the range of the vector, and <i>ok</i> is non-null, *<i>ok</i> is set to TRUE and the returned reference is well defined.</p>

160

164

<h3 class="fn"><a name="at-2"></a>const T & Q3ValueVector::at ( int <i>i</i>, bool * <i>ok</i> = 0 ) const</h3>

161

165

<p>This is an overloaded function.</p>

162

166

<p>Returns a const reference to the element with index <i>i</i>. If <i>ok</i> is non-null, and the index <i>i</i> is out of range, *<i>ok</i> is set to FALSE and the returned reference is undefined. If the index <i>i</i> is within the range of the vector, and <i>ok</i> is non-null, *<i>ok</i> is set to TRUE and the returned reference is well defined.</p>

167

163

168

<h3 class="fn"><a name="resize"></a>void Q3ValueVector::resize ( int <i>n</i>, const T & <i>val</i> = T() )</h3>

164

169

<p>Changes the size of the vector to <i>n</i>. If <i>n</i> is greater than the current <a href="qvector.html#size">size</a>(), elements are added to the end and initialized with the value of <i>val</i>. If <i>n</i> is less than <a href="qvector.html#size">size</a>(), elements are removed from the end. If <i>n</i> is equal to <a href="qvector.html#size">size</a>() nothing happens.</p>

171

<h3 class="fn"><a name="operator-eq"></a>Q3ValueVector<T> & Q3ValueVector::operator= ( const Q3ValueVector<T> & <i>v</i> )</h3>

166

172

<p>Assigns <i>v</i> to this vector and returns a reference to this vector.</p>

167

<p>All iterators of the current vector become invalidated by this operation. The cost of such an assignment is O(1) since <a href="q3valuevector.html">Q3ValueVector</a> is implicitly shared.</p>
