          $sn->state,"\n",
          $sn->vpcId,"\n",

DESCRIPTION

This object supports the EC2 Virtual Private Cloud subnet interface. Please see VM::EC2::Generic for methods shared by all VM::EC2 objects.

METHODS

These object methods are supported:

 subnetId   -- the ID of the subnet
 state      -- The current state of the subnet, either "pending" or "available"
 vpcId      -- The ID of the VPC the subnet is in.
 cidrBlock  -- The CIDR block assigned to the subnet.
 availableIpAddressCount -- The number of unused IP addresses in the subnet.
 availableZone -- This subnet's availability zone.
 defaultForAz  -- Indicates if this is the default subnet for the Availability Zone
 mapPublicIpOnLaunch -- Indicates if instances launched in this subnet automatically receive a
                        public IP address

This class supports the VM::EC2 tagging interface. See VM::EC2::Generic for information.

In addition, this object supports the following convenience methods:

 vpc()                -- Return the associated VM::EC2::VPC object.
 zone()               -- Return the associated VM::EC2::AvailabilityZone object.
 refresh()            -- Refreshes the object from its current state in EC2.
 current_state()      -- Refreshes the object and returns its current state.
 create_route_table() -- Create a new route table, associates it with this subnet, and
                         returns the corresponding VM::EC2::VPC::RouteTable
                         object.
 associate_route_table($table)
                      -- Associates a route table with this subnet, returning true if
                         sucessful.
 disassociate_route_table($table)
                      -- Removes the association of a route table with this subnet. Produces
                         a fatal error if $table is not associated with the subnet. Returns true
                         on success.
 associate_network_acl($network_acl_id)
                      -- Associates a network ACL with this subnet, returning the new
                         association ID on success.
 disassociate_network_acl()
                      -- Removes the association of a network ACL with this subnet. The subnet
                         will then be associated with the default network ACL.  Returns the
                         the association ID.

STRING OVERLOADING

When used in a string context, this object will be interpolated as the subnet ID.
