</PRE>
<P>
<p>The <a href="QBitArray.html#QBitArray()"><tt>QBitArray</tt></a> class provides an array of bits.</p>
<p>A <a href="QBitArray.html#QBitArray()"><tt>QBitArray</tt></a> is an array that gives access to individual bits and provides operators (AND</tt>, OR</tt>, XOR</tt>, and NOT</tt>) that work on entire arrays of bits. It uses implicit sharing</tt> (copy-on-write) to reduce memory usage and to avoid the needless copying of data.</p>
<p>The following code constructs a <a href="QBitArray.html#QBitArray()"><tt>QBitArray</tt></a> containing 200 bits initialized to false (0):</p>
<pre> QBitArray ba(200);</pre>
<p>To initialize the bits to true, either pass <tt>true</tt> as second argument to the constructor, or call <a href="QBitArray.html#fill(boolean, int)"><tt>fill</tt></a> later on.</p>
<p><a href="QBitArray.html#QBitArray()"><tt>QBitArray</tt></a> uses 0-based indexes, just like C++ arrays. To access the bit at a particular index position, you can use operator[](). On non-const bit arrays, operator[]() returns a reference to a bit that can be used on the left side of an assignment. For example:</p>
<pre> QBitArray ba;
ba.resize(3);
ba[0] = true;
ba[1] = false;
ba[2] = true;</pre>
<p>For technical reasons, it is more efficient to use <a href="QBitArray.html#testBit(int)"><tt>testBit</tt></a> and <a href="QBitArray.html#setBit(int, boolean)"><tt>setBit</tt></a> to access bits in the array than operator[](). For example:</p>
<pre> QBitArray ba(3);
ba.setBit(0, true);
ba.setBit(1, false);
ba.setBit(2, true);</pre>
<p><a href="QBitArray.html#QBitArray()"><tt>QBitArray</tt></a> supports <tt>&</tt> (AND</tt>), <tt>|</tt> (OR</tt>), <tt>^</tt> (XOR</tt>), <tt>~</tt> (NOT</tt>), as well as <tt>&=</tt>, <tt>|=</tt>, and <tt>^=</tt>. These operators work in the same way as the built-in C++ bitwise operators of the same name. For example:</p>
<pre> QBitArray x(5);
x.setBit(3, true);
<span class="comment"> // x: [ 0, 0, 0, 1, 0 ]</span>
QBitArray y(5);
y.setBit(4, true);
<span class="comment"> // y: [ 0, 0, 0, 0, 1 ]</span>
x |= y;
<span class="comment"> // x: [ 0, 0, 0, 1, 1 ]</span></pre>
<p>For historical reasons, <a href="QBitArray.html#QBitArray()"><tt>QBitArray</tt></a> distinguishes between a null bit array and an empty bit array. A <i>null</i> bit array is a bit array that is initialized using <a href="QBitArray.html#QBitArray()"><tt>QBitArray</tt></a>'s default constructor. An <i>empty</i> bit array is any bit array with size 0. A null bit array is always empty, but an empty bit array isn't necessarily null:</p>
<pre> QBitArray().isNull(); <span class="comment">// returns true</span>
QBitArray().isEmpty(); <span class="comment">// returns true</span>
QBitArray(0).isNull(); <span class="comment">// returns false</span>
QBitArray(0).isEmpty(); <span class="comment">// returns true</span>
QBitArray(3).isNull(); <span class="comment">// returns false</span>
QBitArray(3).isEmpty(); <span class="comment">// returns false</span></pre>
<p>All functions except <a href="QBitArray.html#isNull()"><tt>isNull</tt></a> treat null bit arrays the same as empty bit arrays; for example, <a href="QBitArray.html#QBitArray()"><tt>QBitArray</tt></a> compares equal to <a href="QBitArray.html#QBitArray()"><tt>QBitArray</tt></a>(0). We recommend that you always use <a href="QBitArray.html#isEmpty()"><tt>isEmpty</tt></a> and avoid <a href="QBitArray.html#isNull()"><tt>isNull</tt></a>.</p>
