50 \class QSourceLocation
51 \reentrant
52 \since 4.4
53 \brief The QSourceLocation class identifies a location in a resource by URI, line, and column.
54 \ingroup xml-tools
55
56 QSourceLocation is a simple value based class that has three
57 properties, uri(), line(), and column(), that, taken together,
58 identify a certain point in a resource, e.g., a file or an in-memory
59 document.
60
61 line() and column() refer to character counts (not byte counts), and
62 they both start from 1, as opposed to 0.
