class Foundation_API Bugcheck
This class provides some static methods that are
used by the
poco_assert_dbg(), poco_assert(), poco_check_ptr()
and poco_bugcheck() macros.
You should not invoke these methods
directly. Use the macros instead, as they
automatically provide useful context information.
{
public:
static void assertion(const char* cond, const char* file, int line);
An assertion failed. Break into the debugger, if
possible, then throw an AssertionViolationException.
static void nullPointer(const char* ptr, const char* file, int line);
An null pointer was encountered. Break into the debugger, if
possible, then throw an NullPointerException.
static void bugcheck(const char* file, int line);
An internal error was encountered. Break into the debugger, if
possible, then throw an BugcheckException.
static void bugcheck(const char* msg, const char* file, int line);
An internal error was encountered. Break into the debugger, if
possible, then throw an BugcheckException.
static void debugger(const char* file, int line);
An internal error was encountered. Break into the debugger, if
possible.
static void debugger(const char* msg, const char* file, int line);
An internal error was encountered. Break into the debugger, if
possible.
