     * filter. </li> <li> <p><code>vpc-id</code> - The ID of the VPC for the
     * subnet. </li> </ul>

     * Returns a reference to this object so that method calls can be chained together.
     *
     * @param filters One or more filters. <ul> <li> <p><code>availabilityZone</code> - The
     *         Availability Zone for the subnet. You can also use
     *         <code>availability-zone</code> as the filter name. </li> <li>
     *         <p><code>available-ip-address-count</code> - The number of IP
     *         addresses in the subnet that are available. </li> <li>
     *         <p><code>cidrBlock</code> - The CIDR block of the subnet. The CIDR
     *         block you specify must exactly match the subnet's CIDR block for
     *         information to be returned for the subnet. You can also use
     *         <code>cidr</code> or <code>cidr-block</code> as the filter names.
     *         </li> <li> <p><code>defaultForAz</code> - Indicates whether this is
     *         the default subnet for the Availability Zone. You can also use
     *         <code>default-for-az</code> as the filter name. </li> <li>
     *         <p><code>state</code> - The state of the subnet (<code>pending</code>
     *         | <code>available</code>). </li> <li> <p><code>subnet-id</code> - The
     *         ID of the subnet. </li> <li>
     *         <p><code>tag</code>:<i>key</i>=<i>value</i> - The key/value
     *         combination of a tag assigned to the resource. </li> <li>
     *         <p><code>tag-key</code> - The key of a tag assigned to the resource.
     *         This filter is independent of the <code>tag-value</code> filter. For
     *         example, if you use both the filter "tag-key=Purpose" and the filter
     *         "tag-value=X", you get any resources assigned both the tag key Purpose
     *         (regardless of what the tag's value is), and the tag value X
     *         (regardless of what the tag's key is). If you want to list only
     *         resources where Purpose is X, see the
     *         <code>tag</code>:<i>key</i>=<i>value</i> filter. </li> <li>
     *         <p><code>tag-value</code> - The value of a tag assigned to the
