Re: Constructor call constructor

Tech-Archive recommends: Speed Up your PC by fixing your registry

Personnaly, I choose to place all the code in the constructor with all the
parameters.

The constructors with minder parameters are only "shortcuts" for the full
constructor

Hi,

IMO it's better to concentrate all the code in only one constructor,
otherwise you may get errors as you include some code in one variant and
not
the other, cause remember that you usually do more than just assign values
to variables.

In your example, what happens with "FromLog " if the first constructor is
called?
because of that yours contructor with partial parameters should call the
constructor with all the parameters and there you do your init:

public SystemEvent(DateTime p_Heure, String p_Porte, String p_TypeEvt)
:
this (p_Heure, p_Porte, p_TypeEvt, false, false)
{}

public SystemEvent(DateTime p_Heure,String p_Porte,String p_TypeEvt,
bool p_FromLog,bool p_WithVerifEvent) {
this.p_FromLog = p_FromLog;
this.p_WithVerifEvent;
this.p_Heure = pHeure;
this.p_Porte = p_Porte;
this.p_TypeEvt = p_TypeEvt;
}

You can do it either way round with constructor chaining:


public class SystemEvent
{

public SystemEvent(DateTime p_Heure, String p_Porte, String
p_TypeEvt)
{
this.p_Heure = pHeure;
this.p_Porte = p_Porte;
this.p_TypeEvt = p_TypeEvt;
}

public SystemEvent(DateTime p_Heure,String p_Porte,String p_TypeEvt,
bool p_FromLog,bool p_WithVerifEvent) : this (p_Heure, p_Porte,
p_TypeEvt)
{
this.p_FromLog = p_FromLog;
this.p_WithVerifEvent;
}

}


Or you can do it the way round you have it, with the constructor with
the
smaller parameter list calling the one with the larger, with default
values. This generates efficient code; calling common methods doesn't.
