I have a base class and derived a class from the base class, i want to print & read the data for the object created for the derived class,so i have overloaded both the << and >> operators and also have done the foward declaration.
Below is the code snippet,

Hello,
i am using the sigaction function to handle the SIGCHLD signal.Is it possible to use a class member function as the handler function (the sa_handler member of the sigaction structure)?
The function's signature is:
void (*sa_handler)(int);so i don't think i can use a static member function... (2 Replies)

Hi friends,
The derived class cannot access the base class's variables in my program. You can have a look at my code, I am actually using class templates.
#include <iostream>
using namespace std;
template <class T>
class Sum

friend void Check(Sum &s, T a, T b)
{
T x,... (2 Replies)

I have the following class and thought that when I call the set command to set a member, I always use value. Would that be fine?

Hi all!
I am trying to register a device in an existing device class, but I am
having trouble getting the pointer to an existing class.
I can create a class in a module, get the pointer to it and then use
it to register the device with:

I have the two class definition as follows.
class A { public: int a; };
class B : virtual public A{ };
The size of class A is shown as 4, and size of class B is shown as 16. Why is this effect ?. (2 Replies)

There is base class B, and two derived classes D1 and D2 derived from Base. Base class B, have two data members ( public or protected or private or if any). D1 should inherit both these data members, and D2 should be deriving only one member from Base class. Is this kind of design possible without... (1 Reply)

Why, here the size of class 'Derived' is 8 ?

};

SOAP::WSDL::XSD::Typelib::SimpleType(3pm) User Contributed Perl Documentation SOAP::WSDL::XSD::Typelib::SimpleType(3pm) NAME
SOAP::WSDL::XSD::Typelib::SimpleType - simpleType base class DESCRIPTION
This module implements a base class for designing simple type classes modelling XML Schema simpleType definitions. SYNOPSIS
# example simpleType derived by restriction # XSD would be: # <simpleType name="MySimpleType"> # <restriction base="xsd:string" /> # </simpleType> package MySimpleType; use Class::Std::Fast::Storable constructor => 'none'; # restriction base implemented via inheritance use SOAP::WSDL::XSD::Typelib::Builtin; use SOAP::WSDL::XSD::Typelib::SimpleType; use base qw( # derive by restriction 'SOAP::WSDL::XSD::Typelib::SimpleType::restriction', # restriction base 'SOAP::WSDL::XSD::Typelib::Builtin::string' ); # example simpleType derived by list. # XSD would be: # <simpleType name="MySimpleListType"> # <list itemTipe="xsd:string" /> # </simpleType> package MySimpleListType; use Class::Std::Fast::Storable constructor => 'none'; # restriction base implemented via inheritance use SOAP::WSDL::XSD::Typelib::Builtin; use base ('SOAP::WSDL::XSD::Typelib::SimpleType', 'SOAP::WSDL::XSD::Typelib::Builtin::list', # derive by list 'SOAP::WSDL::XSD::Typelib::Builtin::string' # list itemType ); How to write your own simple type Writing a simple type class is easy - all you have to do is setting up the base classes correctly. The following rules apply: o simpleType derived via list simpleType classes derived via list must inherit from these classes in exactly this order: SOAP::WSDL::XSD::Typelib::SimpleType SOAP::WSDL::XSD::Typelib::Builtin::list # derive by list The::List::ItemType::Class # list itemType The::List::ItemType::Class can either be a builtin class (see SOAP::WSDL::XSD::Builtin) or another simpleType class (any other class implementing the right methods is supported too, but not for the faint of heart). o simpleType derived via restriction simpleType classes derived via restriction must inherit from these classes in exactly this order: SOAP::WSDL::XSD::Typelib::SimpleType # you may leave this out SOAP::WSDL::XSD::Typelib::SimpleType::restriction # derive by restriction The::Restriction::Base::Class # restriction base The::Restriction::Base::Class can either be a builtin class (see SOAP::WSDL::XSD::Builtin) or another simpleType class. The slight inconsistency between the these variants is caused by the restriction element, which has different meanings for simpleType and complexType definitions. BUGS AND LIMITATIONS
o Thread safety SOAP::WSDL::XSD::Typelib::SimpleType uses Class::Std::Fast::Storable which uses Class::Std. Class::Std is not thread safe, so SOAP::WSDL::XSD::Typelib::SimpleType is neither. o union union simple types are not supported yet. o XML Schema facets No facets are implemented yet.
