< Day Day Up >

SourceLine Description The class SourceLine (see Figure C-12) represents a location in a source code file. It is used to capture the location of an assertion failure. A SourceLine usually is created using the macro CPPUNIT_SOURCELINE( ), which uses the preprocessor directives _ _FILE_ _ and __LINE_ _ to obtain the filename and line number of the location where it's invoked: #define CPPUNIT_SOURCELINE( ) ::CppUnit::SourceLine( __FILE__, __LINE_ _ ) SourceLine belongs to the namespace CppUnit. It is declared in SourceLine.h and implemented in SourceLine.cpp. Figure C-12. The class SourceLine Declaration class SourceLine Constructors/Destructors SourceLine(string &fileName, int lineNumber) A constructor taking a filename and line number. SourceLine( ) A default constructor creating an uninitialized SourceLine. virtual ~SourceLine( ) A destructor. Public Methods bool operator==(const SourceLine &other) const A comparison operator. bool operator!=(const SourceLine &other) const An inequality operator. string fileName( ) const Returns the filename. bool isValid( ) const Returns TRUE if SourceLine is initialized (the filename is not empty). int lineNumber( ) const Returns the line number. Protected/Private Methods RepeatedTest(const RepeatedTest &) A copy constructor declared private to prevent its use. void operator=(const RepeatedTest &) A copy operator declared private to prevent its use. Attributes string m_fileName The source filename (private). int m_lineNumber The source file line number (private).
