Detailed Description

Definition in file mexception.h.

Define Documentation

EXCEPTIONCLASS (  end_of_stream    ) 
 

Value:

class eclass : public Exception {\
public:\
    eclass (const String& what_arg) : Exception (what_arg) { }\
    virtual ~eclass () {;}\
};
End of stream was reached.

Definition at line 81 of file mexception.h.

#define failtrace (  expr    )     failtrace_begin; expr; failtrace_end;
 

If the expr throws an exception, this macro rethrows it, but records the filename and line number in the Exception reason.

Definition at line 139 of file mexception.h.

#define failtrace_begin   try {
 

Failtrace and trywith.

Definition at line 126 of file mexception.h.

#define failtrace_end
 

Value:

} catch (Exception e) { \
        throw forwarded_failure (format ("%s\n%%ERR: Exception forwaded at %s[%d]:%s()", \
                                         (CONSTR) e.what(), __FILE__, __LINE__, __FUNCTION__)); \
    }

Definition at line 127 of file mexception.h.

#define trywith (  expr,
err    ) 
 

Value:

try { \
        expr; \
    } catch (Exception e) { \
        throw forwarded_failure (format ("%s\n%%ERR: Exception forwaded at %s[%d]:%s()\n%%ERR: %s", \
                                         (CONSTR) e.what(), __FILE__, __LINE__, __FUNCTION__, (CONSTR) err)); \
    }
Much like failtrace(expr).

If the expr throws an exception, this macro rethrows it, but records the filename and line number in the Exception reason, as well as additional explanation.

Enumeration Type Documentation

enum assertmodes
 

The Application and ASSERT framework supports many ways of handling assertion fails.

It is, for example, very useful to crash the program (ASSERT_CRASH) if you are running the program under debugger.

Just include in your Main line:

assertmode = ASSERT_CRASH;

Definition at line 166 of file mexception.h.

Function Documentation

void assertwith (  const char *    filename,
int    lineno,
const char *    funcname,
const char *    condition = NULL,
const char *    message = NULL
) 
 

Internal for ASSERT and ASSERTWITH.
