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;

Class::DBI::Test::SQLite(3pm) User Contributed Perl Documentation Class::DBI::Test::SQLite(3pm)
NAME
Class::DBI::Test::SQLite - Base class for Class::DBI tests
SYNOPSIS
use base 'Class::DBI::Test::SQLite';
__PACKAGE__->set_table('test');
__PACKAGE__->columns(All => qw/id name film salary/);
sub create_sql {
return q{
id INTEGER PRIMARY KEY,
name CHAR(40),
film VARCHAR(255),
salary INT
}
}
DESCRIPTION
This provides a simple base class for Class::DBI tests using SQLite. Each class for the test should inherit from this, provide a
create_sql() method which returns a string representing the SQL used to create the table for the class, and then call set_table() to create
the table, and tie it to the class.
METHODS
set_table
__PACKAGE__->set_table('test');
This combines creating the table with the normal Class::DBI table() call.
create_sql (abstract)
sub create_sql {
return q{
id INTEGER PRIMARY KEY,
name CHAR(40),
film VARCHAR(255),
salary INT
}
}
This should return, as a text string, the schema for the table represented by this class.
