NAME
parent - Establish an ISA relationship with base classes at compile time
SYNOPSIS
DESCRIPTION
Allows you to both load one or more modules, while setting up inheritance from those modules at the same time. Mostly similar in effect to
By default, every base class needs to live in a file of its own. If you want to have a subclass and its parent class in the same file, you can tell parent
not to load any modules by using the -norequire
switch:
package
Foo;
sub
exclaim {
"I CAN HAS PERL"
}
package
DoesNotLoadFooBar;
# will not go looking for Foo.pm or Bar.pm
This is equivalent to the following code:
package
Foo;
sub
exclaim {
"I CAN HAS PERL"
}
package
DoesNotLoadFooBar;
push
@DoesNotLoadFooBar::ISA
,
'Foo'
,
'Bar'
;
This is also helpful for the case where a package lives within a differently named file:
This is equivalent to the following code:
If you want to load a subclass from a file that require
would not consider an eligible filename (that is, it does not end in either .pm
or .pmc
), use the following code:
package
MySecondPlugin;
require
'./plugins/custom.plugin'
;
# contains Plugin::Custom
HISTORY
