NAME

Reflex::Callback::CodeRef - Callback adapter for plain code references

VERSION

This document describes version 0.100, released on April 02, 2017.

SYNOPSIS

Used within Reflex:

        use Reflex::Callbacks qw(cb_coderef);

        my $ct = Reflex::Interval->new(
                interval    => 1 + rand(),
                auto_repeat => 1,
                on_tick     => cb_coderef {
                        print "coderef callback triggered\n";
                },
        );

        $ct->run_all();

Low-level usage:

        sub callback {
                my $arg = shift;
                print "hello, $arg->{name}\n";
        }

        use Reflex::Callback;
        my $cb = Reflex::Callback::CodeRef->new( code_ref => \&code );
        $cb->deliver(greet => { name => "world" });

DESCRIPTION

Reflex::Callback::CodeRef maps the generic Reflex::Callback interface to plain coderef callbacks. Reflex::Callbacks' cb_coderef() function and other syntactic sweeteners hide the specifics.

new

Reflex::Callback::CodeRef's constructor takes a single named parameter, "code_ref", which should contain the coderef to be called by deliver().

deliver

Reflex::Callback::CodeRef's deliver() method invokes the coderef supplied during the callback's construction. deliver() takes two positional parameters: an event name (which is not currently used for coderef callbacks), and a hashref of named parameters to be passed to the callback.

deliver() returns whatever the coderef does.
