=head1 NAME

Test2::Event::Generic - Generic event type.

=head1 DESCRIPTION

This is a generic event that lets you customize all fields in the event API.
This is useful if you have need for a custom event that does not make sense as
a published reusable event subclass.

=head1 SYNOPSIS

    use Test2::API qw/context/;

    sub send_custom_fail {
        my $ctx = shift;

        $ctx->send_event('Generic', causes_fail => 1, summary => 'The sky is falling');

        $ctx->release;
    }

    send_custom_fail();

=head1 METHODS

=over 4

=item $e->facet_data($data)

=item $data = $e->facet_data

Get or set the facet data (see L<Test2::Event>). If no facet_data is set then
C<< Test2::Event->facet_data >> will be called to produce facets from the other
data.

=item $e->callback($hub)

Call the custom callback if one is set, otherwise this does nothing.

=item $e->set_callback(sub { ... })

Set the custom callback. The custom callback must be a coderef. The first
argument to your callback will be the event itself, the second will be the
L<Test2::Event::Hub> that is using the callback.

=item $bool = $e->causes_fail

=item $e->set_causes_fail($bool)

Get/Set the C<causes_fail> attribute. This defaults to C<0>.

=item $bool = $e->diagnostics

=item $e->set_diagnostics($bool)

Get/Set the C<diagnostics> attribute. This defaults to C<0>.

=item $bool_or_undef = $e->global

=item @bool_or_empty = $e->global

=item $e->set_global($bool_or_undef)

Get/Set the C<diagnostics> attribute. This defaults to an empty list which is
undef in scalar context.

=item $bool = $e->increments_count

=item $e->set_increments_count($bool)

Get/Set the C<increments_count> attribute. This defaults to C<0>.

=item $bool = $e->no_display

=item $e->set_no_display($bool)

Get/Set the C<no_display> attribute. This defaults to C<0>.

=item @plan = $e->sets_plan

Get the plan if this event sets one. The plan is a list of up to 3 items:
C<($count, $directive, $reason)>. C<$count> must be defined, the others may be
undef, or may not exist at all.

=item $e->set_sets_plan(\@plan)

Set the plan. You must pass in an arrayref with up to 3 elements.

=item $summary = $e->summary

=item $e->set_summary($summary_or_undef)

Get/Set the summary. This will default to the event package
C<'Test2::Event::Generic'>. You can set it to any value. Setting this to
C<undef> will reset it to the default.

=item $int_or_undef = $e->terminate

=item @int_or_empty = $e->terminate

=item $e->set_terminate($int_or_undef)

This will get/set the C<terminate> attribute. This defaults to undef in scalar
context, or an empty list in list context. Setting this to undef will clear it
completely. This must be set to a positive integer (0 or larger).
