=head1 NAME
VM::EC2::NetworkInterface::Attachment -- Object representing attachment of a network interface to an instance
=head1 SYNOPSIS
use VM::EC2;
my $ec2 = VM::EC2->new(...);
my $instance = $ec2->describe_instances('i-123456');
my @interfaces = $instance->network_interfaces();
for my $i (@interfaces) {
my $attachment = $i->attachment;
my $att_id = $attachment->attachmentId;
my $ins_id = $attachment->instanceId;
my $instance = $attachment->instance;
my $device = $attachment->device;
my $status = $attachment->status;
my $time = $attachment->attachmentTime;
my $delete = $attachment->deleteOnTermination;
}
=head1 DESCRIPTION
This object describes the attachment of a elastic network interface
(ENI) to an instance, and allows you to manipulate the attachment.
Please see L<VM::EC2::Generic> for methods shared by all VM::EC2
objects.
=head1 METHODS
These object methods are supported:
attachmentId -- ID of the attachment
instanceId -- ID of the instance
instanceOwnerId -- ID of the owner of the instance
deviceIndex -- Ethernet device number, e.g. "0" for eth0
status -- Always "attached"; see below.
attachmentTime -- Time this ENI was attached to the instance, as a DateTime
deleteOnTermination -- If true, this ENI will be deleted when the instance terminates.
Amazon does not document the network interface attachment object well,
and many of these fields are inferred by inspection of EC2 REST
responses. In particular, the status field always seems to be
"attached", but there may be another state, such as "pending", which
is too short lived to be apparent.
In addition, this object supports the following convenience methods:
instance -- The VM::EC2::Instance to which the ENI is attached.
=head1 STRING OVERLOADING
When used in a string context, this object will be interpolated as the
attachmentId.
