NAME

Rinchi::CIGIPP::EventNotification - Perl extension for the Common Image Generator Interface - Event Notification data packet. data packet. =head1 SYNOPSIS

  use Rinchi::CIGIPP::EventNotification;
  my $evt_ntc = Rinchi::CIGIPP::EventNotification->new();

  $packet_type = $evt_ntc->packet_type();
  $packet_size = $evt_ntc->packet_size();
  $event_ident = $evt_ntc->event_ident(37952);
  $event_data1 = $evt_ntc->event_data1(285);

  $event_data3 = $evt_ntc->event_data3(12715);

DESCRIPTION

The Event Notification packet is used to pass event data to the Host. The Host may enable and disable individual events using either the Component Control or Short Component Control packet.

This packet contains three user-defined 32-bit word values that may contain data describing the attributes of the event (e.g., time of occurrence, position). These data may be formatted as needed; however, they must be byte-swapped as 32-bit fields when byte swapping is necessary. Refer to the description of the Component Control packet for more information.

EXPORT

None by default.

new $evt_ntc = Rinchi::CIGIPP::EventNotification->new()

Constructor for Rinchi::EventNotification.

sub packet_type()

 $value = $evt_ntc->packet_type();

Data Packet Identifier.

This attribute identifies this data packet as the Event Notification packet. The value of this attribute must be 116.

sub packet_size()

 $value = $evt_ntc->packet_size();

Data Packet Size.

This attribute indicates the number of bytes in this data packet. The value of this attribute must be 16.

sub event_ident([$newValue])

 $value = $evt_ntc->event_ident($newValue);

Event ID.

This attribute indicates which event has occurred. Event ID assignments are IG-specific.

sub event_data1([$newValue])

Event Data 1.

This attribute is one of three 32-bit words used for user-defined event data. If this attribute is not needed to describe the event, this value is ignored.

Note: This attribute will be byte-swapped as a 32-bit value if the receiver and sender use different byte ordering schemes. If the attribute is used to store multiple 8- or 16-bit values, the data should be packed so that byte swapping will be performed correctly. Use event_data1_short1 and event_data1_short2 for 16-bit values, or event_data1_byte1, event_data1_byte2, event_data1_byte3, and event_data1_byte4 for 8-bit values.
