Test2::Event::V2(3pm) Perl Programmers Reference Guide Test2::Event::V2(3pm)

Test2::Event::V2 - Second generation event.

This is the event type that should be used instead of Test2::Event or its legacy subclasses.

USING A CONTEXT

    use Test2::API qw/context/;
    sub my_tool {
        my $ctx = context();
        my $event = $ctx->send_ev2(info => [{tag => 'NOTE', details => "This is a note"}]);
        $ctx->release;
        return $event;
    }

USING THE CONSTRUCTOR

    use Test2::Event::V2;
    my $e = Test2::Event::V2->new(
        trace => {frame => [$PKG, $FILE, $LINE, $SUBNAME]},
        info  => [{tag => 'NOTE', details => "This is a note"}],
    );

This class inherits from Test2::Event.

$fd = $e->facet_data()
This will return a hashref of facet data. Each facet hash will be a shallow copy of the original.
$about = $e->about()
This will return the 'about' facet hashref.

NOTE: This will return the internal hashref, not a copy.

$trace = $e->trace()
This will return the 'trace' facet, normally blessed (but this is not enforced when the trace is set using "set_trace()".

NOTE: This will return the internal trace, not a copy.

MUTATION

$e->add_amnesty({...})
Inherited from Test2::Event. This can be used to add 'amnesty' facets to an existing event. Each new item is added to the END of the list.

NOTE: Items ARE blessed when added.

$e->add_hub({...})
Inherited from Test2::Event. This is used by hubs to stamp events as they pass through. New items are added to the START of the list.

NOTE: Items ARE NOT blessed when added.

$e->set_uuid($UUID)
Inherited from Test2::Event, overridden to also vivify/mutate the 'about' facet.
$e->set_trace($trace)
Inherited from Test2::Event which allows you to change the trace.

Note: This method does not bless/clone the trace for you. Many things will expect the trace to be blessed, so you should probably do that.

LEGACY SUPPORT METHODS

These are all imported from Test2::Util::Facets2Legacy, see that module or Test2::Event for documentation on what they do.

This object consumes Test2::Util::ExternalMeta which provides a consistent way for you to attach meta-data to instances of this class. This is useful for tools, plugins, and other extensions.
