lib:base

See the current Perl documentation for lib:base.

Here is our local, out-dated (pre-5.6) version:


base - Establish IS-A relationship with base class at compile time



    package Baz;
    use base qw(Foo Bar);



Roughly similar in effect to

    BEGIN {
        require Foo;
        require Bar;
        push @ISA, qw(Foo Bar);
    }

Will also initialize the %FIELDS hash if one of the base classes has it. Multiple inheritance of %FIELDS is not supported. The 'base' pragma will croak if multiple base classes has a %FIELDS hash. See fields for a description of this feature.

When strict 'vars' is in scope base also let you assign to @ISA without having to declare @ISA with the 'vars' pragma first.

This module was introduced with Perl 5.004_04.

[Corion]: ambrus: Yeah, at least that's what I think I'll start with. A timer and potentially the dummy IO function that never is ready
[ambrus]: That only lets you invoke the main loop from Prima->run;, not from AnyEvent->condvar- >recv; but that shouldn't matter
[Corion]: ambrus: Details ;)
[ambrus]: Like <c>{ package AnyEvent::Impl:: Prima; use Prima; sub io{ my($s,%r)=@_; Prima::File->new( file=>$r{fh},mask =>("w"eq$r{poll}? fe::Write():fe:: Read())|fe:: Exception,onRead =>$r{cb},onWrite =>$r{cb}, onException=>$r{cb }) } sub timer { ... } push @AnyEvent::REGI
[ambrus]: argh, too long, let me try on scratchpad
