<!-- $$$QMediaTimeInterval-description -->
<div class="descr">
<h2 id="details">Detailed Description</h2>
<p>The <a href="qmediatimeinterval.html">QMediaTimeInterval</a> class represents a time interval with integer precision.</p>
<p>An interval is specified by an inclusive <a href="qmediatimeinterval.html#start">start</a>() and <a href="qmediatimeinterval.html#end">end</a>() time. These must be set in the constructor, as this is an immutable class. The specific units of time represented by the class have not been defined - it is suitable for any times which can be represented by a signed 64 bit integer.</p>
<p>The <a href="qmediatimeinterval.html#isNormal">isNormal</a>() method determines if a time interval is normal (a normal time interval has <a href="qmediatimeinterval.html#start">start</a>() <= <a href="qmediatimeinterval.html#end">end</a>()). A normal interval can be received from an abnormal interval by calling the <a href="qmediatimeinterval.html#normalized">normalized</a>() method.</p>
<p>The <a href="qmediatimeinterval.html#contains">contains</a>() method determines if a specified time lies within the time interval.</p>
<p>The <a href="qmediatimeinterval.html#translated">translated</a>() method returns a time interval which has been translated forwards or backwards through time by a specified offset.</p>

<h3 class="fn" id="contains"><a name="contains"></a><span class="type">bool</span> QMediaTimeInterval::<span class="name">contains</span>(<span class="type">qint64</span> <i>time</i>) const</h3>
<p>Returns true if the time interval contains the specified <i>time</i>. That is, <a href="qmediatimeinterval.html#start">start</a>() <= time <= <a href="qmediatimeinterval.html#end">end</a>().</p>
<!-- @@@contains -->
<!-- $$$end[overload1]$$$end -->
<h3 class="fn" id="end"><a name="end"></a><span class="type">qint64</span> QMediaTimeInterval::<span class="name">end</span>() const</h3>

<!-- $$$isNormal[overload1]$$$isNormal -->
<h3 class="fn" id="isNormal"><a name="isNormal"></a><span class="type">bool</span> QMediaTimeInterval::<span class="name">isNormal</span>() const</h3>
<p>Returns true if this time interval is normal. A normal time interval has <a href="qmediatimeinterval.html#start">start</a>() <= <a href="qmediatimeinterval.html#end">end</a>().</p>

<p>Returns a normalized version of this interval.</p>
<p>If the <a href="qmediatimeinterval.html#start">start</a>() time of the interval is greater than the <a href="qmediatimeinterval.html#end">end</a>() time, then the returned interval has the start and end times swapped.</p>
