=head1 NAME
VM::EC2::Group - Object describing an Amazon EC2 security group name
=head1 SYNOPSIS
use VM::EC2;
$ec2 = VM::EC2->new(...);
$instance = $ec2->describe_instances(-instance_id=>'i-12345');
my @groups = $instance->groups;
for my $g (@groups) {
my $id = $g->groupId;
my $name = $g->groupName;
# get the security group details
my $sg = $ec2->describe_security_group($g);
my $permissions = $sg->ipPermissions;
}
=head1 DESCRIPTION
This object represents the name and ID of a security group. It is
returned by an instance's groups() method. This object does not
provide any of the details about the security group, but you can use
it in a call to VM::EC2->describe_security_group() to get details about
the security group's allowed ports, etc.
=head1 METHODS
These object methods are supported:
groupId -- the group ID
groupName -- the group's name
For convenience, the object also provides a permissions() method that
will return the fully detailed VM::EC2::SecurityGroup:
$details = $group->permissions()
See L<VM::EC2::SecurityGroup>
=head1 STRING OVERLOADING
When used in a string context, this object will interpolate the
groupId.
