NAME

Amon2::Trigger - Trigger system for Amon2

SYNOPSIS

    package MyClass;
    use parent qw/Amon2::Trigger/;

    __PACKAGE__->add_trigger('Foo');
    __PACKAGE__->call_trigger('Foo');

This is a trigger system for Amon2. You can use this class for your class using trigger system.

"__PACKAGE__->add_trigger($name:Str, \&code:CodeRef)"

"$obj->add_trigger($name:Str, \&code:CodeRef)"

You can register the callback function for the class or object.

When you register callback code on object, the callback is only registered to object, not for class.

Return Value: Not defined.

"__PACKAGE__->call_trigger($name:Str);"

"$obj->call_trigger($name:Str);"

This method calls all callback code for $name.

Return Value: Not defined.

"__PACKAGE__->get_trigger_code($name:Str)"

"$obj->get_trigger_code($name:Str)"

You can get all of trigger code from the class and ancestors.

WHY DON'T YOU USE Class::Trigger?: Class::Trigger does not support get_trigger_code.
