<h2>Detailed Description</h2>
<p>The QSourceLocation class identifies a location in a resource by URI, line, and column.</p>
<p>QSourceLocation is a simple value based class that has three properties, <a href="qsourcelocation.html#uri">uri</a>(), <a href="qsourcelocation.html#line">line</a>(), and <a href="qsourcelocation.html#column">column</a>(), that, taken together, identify a certain point in a resource, e.g., a file or an in-memory document.</p>
<p><a href="qsourcelocation.html#line">line</a>() and <a href="qsourcelocation.html#column">column</a>() refer to character counts (not byte counts), and they both start from 1, as opposed to 0.</p>
