Single ton class operator

Hi,

I have the following problem:

I have a singleton of a class and this class has just NEN <<operator. But while compiling I get the following error:

Code:

error C2296: '<<' : illegal, left operand has type 'class CLog *'
error C2297: '<<' : illegal, right operand has type 'char [5]'

Here's the code:

Code:

// CLog.h
class CLog
{
public:
    static CLog      *getInstance   (void) { return (&m_Instance); }

    void setFile (const char *FileName = "Protokoll.htm");

    CLog& operator<< (void* n);

private:
    CLog (void);

    static  CLog    m_Instance;

    std::ofstream   m_Stream;
}; 

the cpp:

Code:

#include "CLog.h"

CLog CLog::m_Instance;

CLog::CLog(void)
{
}

CLog& CLog::operator<< ( void* n )
{    
    this->m_Stream << n;

    return (*this);
} 

and here the main.cpp:

Code:

#include "CLog.h"

int main (void)
{
    CLog            *p_Protokoll;
    p_Protokoll     = CLog::getInstance ();

    p_Protokoll << "Test" << std::endl;

    return(false);
}

I have to rebuild the Singleton or how I get the <<operators, to the run it? : Confused:

 

you work with in the refernzen or dereferenzierst pointer

Code:

int main (void)
{
    CLog            *p_Protokoll;
    p_Protokoll     = CLog::getInstance ();

    *p_Protokoll << "Test" << std::endl;

    return(false);
}  

ahja

Code:

CLog            *p_Protokoll;
    p_Protokoll     = CLog::getInstance (); 

Although this rule does not apply when buldins, the link is preventive

false becomes a convertiert and returned in the return-value of main means anything other than 0, but an error

 

How can you ahja std:: endl stream in your clogs?

 

Thanks for the info. would put on the change, oh yeah, this is the pointer just fine, but no gibbet "elegant" solution?

For write this is extremely ugly at the beginning:

Code:

*p_Protokoll << "Test" << "test2";	

Is there the possibility that some things done this:

Code:

Protokoll << "Test" << "Test2";	

 

Code:

CLog & Protokoll = *CLog::getInstance();

I would also modify the type of return of getInstanz from pointer to reference

 

Sure!

Code:

CLog &Protokoll = *CLog::getInstance();

Protokoll << "muhkuh"; 

 

Hm, so I've now made the getInstance Ner reference, but there are still errors.

Code:

static CLog      &getInstance   (void) { return (m_Instance); }

and I get on the line here:

Code:

CLog &Protokoll = *CLog::getInstance();

this error:

Code:

error C2100: illegal indirection	

 

If you give back ne reference do not need to dereference (leave out the *)

 

sorry but your operator <<is the biggest waste. Look at you n little in STL Source to take next, or the best book on hand.

 

Hi,

if I write:

Code:

CLog &Protokoll = *CLog::getInstance();

smears from the program

 

Yes, because you dereferenzierst. You shall leave out the *

 

if I omit it compiles without error, but when running it from a functional smears

 

habs got done ", thx for the help

@ LasT:
such as you would <The operator <do? : Confused:

 

Code:

template<class T>
CLog& operator<<(T& t)
{
m_Stream << t; 

Your probably not even work yet
