=head1 NAME
VM::EC2::ElasticAddress - Object describing an Amazon EC2 Elastic Address
=head1 SYNOPSIS
use VM::EC2;
$ec2 = VM::EC2->new(...);
$addr = $ec2->allocate_address;
$ip = $addr->publicIp;
$domain = $addr->domain;
$allId = $addr->allocationId;
=head1 DESCRIPTION
This object represents an Amazon EC2 elastic address and is returned by
by VM::EC2->allocate_address().
=head1 METHODS
These object methods are supported:
publicIp -- Public IP of the address
domain -- Type of address, either "standard" or "vpc"
allocationId -- For VPC addresses only, an allocation ID
instanceId -- If the address is associated with an instance, the
ID of that instance.
associationId -- If the address is a VPC elastic IP, and associated
with an instance, then the ID of the association.
In addition, the following convenience methods are provided:
=head2 $result = $addr->associate($instance_id)
Associate this address with the given instance ID or
VM::EC2::Instance object. If successful, the result code will be
true for an ordinary EC2 Elastic IP,or equal to the associationId for
a VPC Elastic IP address.
=head2 $result = $addr->disassociate()
Disassociate this address with any instance it is already associated
with. If successful, this method will return true.
=head2 $addr->refresh()
This is an internal function called after associate() and
disassociate(), and is used to refresh the address object's contents.
=head1 STRING OVERLOADING
When used in a string context, this object will interpolate the
publicIp.
