Can someone tell me how to do this?
Just a thought that entered my mind when learning about structs.
First thought was:
struct one
{
struct two;
}
struct two
{
three;
}
one->two->three
would this be how you would access "three"? (1 Reply)

Hi,
Time for me to take a formal class/course on Perl. I was wondering if someone here can recommend an on-line class. My institution will cover the expenses, and therefore, I am not worry about the cost. I am lookin for a beginner course with possibilities to take intermediate and advance... (2 Replies)
Hi,
I have received an application that stores some properties in a file. The existing struct looks like this:
struct TData
{
UINT uSizeIncludingStrings;
// copy of Telnet data struct

// basic properties:

UINT iPortNr;

Hi,
I believe the next code is wrong:
class Egg {
Egg e;
int i;
Egg(int ii=0) : i(ii) {}
};
because you would end up with an endless definition (memory allocation) of Egg objects, thus int i.
Ok, so God Eckel proposes for a singleton:
class Egg {
static Egg e;

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:
*cl = class_create(THIS_MODULE, className);... (0 Replies)
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)

MakeMethods::Emulator::Struct(3pm) User Contributed Perl Documentation MakeMethods::Emulator::Struct(3pm)NAME
Class::MakeMethods::Emulator::Struct - Emulate Class::Struct
SYNOPSIS
use Class::MakeMethods::Emulator::Struct;
struct (
simple => '$',
ordered => '@',
mapping => '%',
obj_ref => 'FooObject'
);
DESCRIPTION
This module emulates the functionality of Class::Struct by munging the provided field-declaration arguments to match those expected by
Class::MakeMethods.
It supports the same four types of accessors, the choice of array-based or hash-based objects, and the choice of installing methods in the
current package or a specified target.
EXAMPLE
The below three declarations create equivalent methods for a simple hash-based class with a constructor and four accessors.
use Class::Struct;
struct (
simple => '$',
ordered => '@',
mapping => '%',
obj_ref => 'FooObject'
);
use Class::MakeMethods::Emulator::Struct;
struct (
simple => '$',
ordered => '@',
mapping => '%',
obj_ref => 'FooObject'
);
use Class::MakeMethods (
-MakerClass => 'Standard::Array',
'new' => 'new',
'scalar' => 'simple',
'array -auto_init 1' => 'ordered',
'hash -auto_init 1' => 'mapping',
'object -auto_init 1' => '-class FooObject obj_ref'
);
COMPATIBILITY
This module aims to offer a "95% compatible" drop-in replacement for the core Class::Struct module for purposes of comparison and code
migration.
The "class-struct.t" test for the core Class::Struct module is included with this package. The test is unchanged except for the a direct
substitution of this emulator's name in the place of the core module.
However, there are numerous internal differences between the methods generated by the original Class::Struct and this emulator, and some
existing code may not work correctly without modification.
SEE ALSO
See Class::MakeMethods for general information about this distribution.
See Class::MakeMethods::Emulator for more about this family of subclasses.
See Class::Struct for documentation of the original module.
See Class::MakeMethods::Standard::Hash and Class::MakeMethods::Standard::Array for documentation of the created methods.
