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 .
