be quickly matched in a Unicode string.</p>
<p>This class is useful when you have a sequence of <a href="qchar.html">QChar</a>s that you want to repeatedly match against
some strings (perhaps in a loop), or when you want to search for
the same sequence of characters multiple times in the same string.
Using a matcher object and <a href="qstringmatcher.html#indexIn">indexIn</a>() is faster than matching
a plain <a href="qstring.html">QString</a> with <a href="qstring.html#indexOf">QString.indexOf</a>() if repeated matching
takes place. This class offers no benefit if you are doing one-off
string matches.</p>
<p>Create the QStringMatcher with the <a href="qstring.html">QString</a> you want to search for. Then call
<a href="qstringmatcher.html#indexIn">indexIn</a>() on the <a href="qstring.html">QString</a> that you want to search.</p>
<hr /><h2>Method Documentation</h2><h3 class="fn"><a name="QStringMatcher" />QStringMatcher.__init__ (<i>self</i>)</h3><p>Constructs an empty string matcher that won't match anything.
Call <a href="qstringmatcher.html#setPattern">setPattern</a>() to
give it a pattern to match.</p>


<h3 class="fn"><a name="QStringMatcher-2" />QStringMatcher.__init__ (<i>self</i>, QString&#160;<i>pattern</i>, <a href="qt.html#CaseSensitivity-enum">Qt.CaseSensitivity</a>&#160;<i>cs</i>&#160;=&#160;Qt.CaseSensitive)</h3><p>Constructs a string matcher that will search for <i>pattern</i>,
with case sensitivity <i>cs</i>.</p>
<p>Call <a href="qstringmatcher.html#indexIn">indexIn</a>() to
perform a search.</p>


<h3 class="fn"><a name="QStringMatcher-3" />QStringMatcher.__init__ (<i>self</i>, <a href="qstringmatcher.html">QStringMatcher</a>&#160;<i>other</i>)</h3><p>Constructs a string matcher that will search for the pattern
referred to by <i>uc</i> with the given <i>length</i> and case
sensitivity specified by <i>cs</i>.</p>
<p>This function was introduced in Qt 4.5.</p>


<h3 class="fn"><a name="caseSensitivity" /><a href="qt.html#CaseSensitivity-enum">Qt.CaseSensitivity</a> QStringMatcher.caseSensitivity (<i>self</i>)</h3><p>Returns the case sensitivity setting for this string
matcher.</p>
<p><b>See also</b> <a href="qstringmatcher.html#setCaseSensitivity">setCaseSensitivity</a>().</p>


<h3 class="fn"><a name="indexIn" />int QStringMatcher.indexIn (<i>self</i>, QString&#160;<i>str</i>, int&#160;<i>from</i>&#160;=&#160;0)</h3><p>Searches the string <i>str</i> from character position
<i>from</i> (default 0, i.e. from the first character), for the
string <a href="qstringmatcher.html#pattern">pattern</a>() that was
set in the constructor or in the most recent call to <a href="qstringmatcher.html#setPattern">setPattern</a>(). Returns the
position where the <a href="qstringmatcher.html#pattern">pattern</a>() matched in <i>str</i>,
or -1 if no match was found.</p>
<p><b>See also</b> <a href="qstringmatcher.html#setPattern">setPattern</a>() and <a href="qstringmatcher.html#setCaseSensitivity">setCaseSensitivity</a>().</p>


<h3 class="fn"><a name="pattern" />QString QStringMatcher.pattern (<i>self</i>)</h3><p>Returns the string pattern that this string matcher will search
for.</p>
<p><b>See also</b> <a href="qstringmatcher.html#setPattern">setPattern</a>().</p>


<h3 class="fn"><a name="setCaseSensitivity" />QStringMatcher.setCaseSensitivity (<i>self</i>, <a href="qt.html#CaseSensitivity-enum">Qt.CaseSensitivity</a>&#160;<i>cs</i>)</h3><p>Sets the case sensitivity setting of this string matcher to
<i>cs</i>.</p>
<p><b>See also</b> <a href="qstringmatcher.html#caseSensitivity">caseSensitivity</a>(),
<a href="qstringmatcher.html#setPattern">setPattern</a>(), and
<a href="qstringmatcher.html#indexIn">indexIn</a>().</p>


<h3 class="fn"><a name="setPattern" />QStringMatcher.setPattern (<i>self</i>, QString&#160;<i>pattern</i>)</h3><p>Sets the string that this string matcher will search for to
<i>pattern</i>.</p>
<p><b>See also</b> <a href="qstringmatcher.html#pattern">pattern</a>(), <a href="qstringmatcher.html#setCaseSensitivity">setCaseSensitivity</a>(),
