when constructor being called

[ermithun]

please refer the code below,

    /**
     * Constructs an empty std::list
     */
    LDAPControlSet();

only this much is there in its respective class,LDAPControlSet. i want to understand that how does it create an empty list from std when nothing's there in its below constructors?? Moreover, the below constructors are the copy-constructors..

Please help!!

LDAPControlSet::LDAPControlSet(){
}

LDAPControlSet::LDAPControlSet(const LDAPControlSet& cs){
    DEBUG(LDAP_DEBUG_CONSTRUCT,"LDAPControlSet::LDAPControlSet(&)" << endl);
    data=cs.data;
}

LDAPControlSet::LDAPControlSet(LDAPControl** controls){
    DEBUG(LDAP_DEBUG_CONSTRUCT,"LDAPControlSet::LDAPControlSet()" << endl);
    if(controls != 0){
        LDAPControl** i;
        for( i=controls; *i!=0;i++) {
            add(LDAPCtrl(*i));
        }
    }
}

ermithun,

Never post source code without bb code tags. Your source code must be suddounded with BB code tags - Read - How to use BB code tags.

Does the class-declaration already have a member of type std::list ?
If so, The list is created there itself and doesn't require any explicit modifications.

I pretty-much did not understand your question very well. Would you mind rephrasing it .

[ermithun]

I apologize adatapost, i have used BB codes now..

Sky Diploma,
I have rephrased my statements as well now..

i meant to ask that the class declaration does not have any member like std::list but only the typedef statement,
typedef std::list<LDAPCtrl> CtrlList;

the below constructors are actually the copy constructors

LDAPControlSet::LDAPControlSet(){
}

LDAPControlSet::LDAPControlSet(const LDAPControlSet& cs){
DEBUG(LDAP_DEBUG_CONSTRUCT,"LDAPControlSet::LDAPControlSet(&)" << endl);
data=cs.data;
}

in the above code, where the 'data' comes from?

LDAPControlSet::LDAPControlSet(LDAPControl** controls){
DEBUG(LDAP_DEBUG_CONSTRUCT,"LDAPControlSet::LDAPControlSet()" << endl);
if(controls != 0){
LDAPControl** i;
for( i=controls; *i!=0;i++) {
add(LDAPCtrl(*i));
}
}
}

Hello Sky Diploma

i confirm that the class-declaration doesnt have a member of type std::list, so how do I declare or create this list?

please help
Thanks.

Hey Post down the whole code or the class declaration just in case,

[ermithun]

yeah sure, please refer the class LDAPControlSet below,

class LDAPControlSet {
    typedef CtrlList::const_iterator const_iterator;
    public :
        LDAPControlSet();

        LDAPControlSet(const LDAPControlSet& cs);

        LDAPControlSet(LDAPControl** controls);

        ~LDAPControlSet();

        size_t size() const ;

        bool empty() const;

        const_iterator begin() const;

        const_iterator end() const;

        void add(const LDAPCtrl& ctrl);

        LDAPControl** toLDAPControlArray()const ;
        static void freeLDAPControlArray(LDAPControl **ctrl);
    private :
        CtrlList data;
} ;

[Sky Diploma]

Well this answers it,

private:
CtrlList data;

This is the empty list that will be created, If I am not wrong, I think we have gone through the typedef definition of CtrlList in one of the other Threads that you have started :)

Many thanks Sky diploma. yes i got your point now.
