<p>The scope at which the extensions are visible and usable in CloudFormation operations.</p> <p>Valid values include:</p> <ul> <li> <p> <code>PRIVATE</code>: Extensions that are visible and usable within this account and region. This includes:</p> <ul> <li> <p>Private extensions you have registered in this account and region.</p> </li> <li> <p>Public extensions that you have activated in this account and region.</p> </li> </ul> </li> <li> <p> <code>PUBLIC</code>: Extensions that are publicly visible and available to be activated within any Amazon Web Services account. This includes extensions from Amazon Web Services, in addition to third-party publishers.</p> </li> </ul> <p>The default is <code>PRIVATE</code>.</p>

<p>For resource types, the provisioning behavior of the resource type. CloudFormation determines the provisioning type during registration, based on the types of handlers in the schema handler package submitted.</p> <p>Valid values include:</p> <ul> <li> <p> <code>FULLY_MUTABLE</code>: The resource type includes an update handler to process updates to the type during stack update operations.</p> </li> <li> <p> <code>IMMUTABLE</code>: The resource type doesn't include an update handler, so the type can't be updated and must instead be replaced during stack update operations.</p> </li> <li> <p> <code>NON_PROVISIONABLE</code>: The resource type doesn't include create, read, and delete handlers, and therefore can't actually be provisioned.</p> </li> </ul> <p>The default is <code>FULLY_MUTABLE</code>.</p>

<p>The deprecation status of the extension that you want to get summary information about.</p> <p>Valid values include:</p> <ul> <li> <p> <code>LIVE</code>: The extension is registered for use in CloudFormation operations.</p> </li> <li> <p> <code>DEPRECATED</code>: The extension has been deregistered and can no longer be used in CloudFormation operations.</p> </li> </ul>

The type of extension.

<p>Filter criteria to use in determining which extensions to return.</p> <p>Filters must be compatible with <code>Visibility</code> to return valid results. For example, specifying <code>AWS_TYPES</code> for <code>Category</code> and <code>PRIVATE</code> for <code>Visibility</code> returns an empty list of types, but specifying <code>PUBLIC</code> for <code>Visibility</code> returns the desired list.</p>

The maximum number of results to be returned with a single call. If the number of available results exceeds this maximum, the response includes a <code>NextToken</code> value that you can assign to the <code>NextToken</code> request parameter to get the next set of results.

If the previous paginated request didn't return all the remaining results, the response object's <code>NextToken</code> parameter value is set to a token. To retrieve the next set of results, call this action again and assign that token to the request object's <code>NextToken</code> parameter. If there are no remaining results, the previous response object's <code>NextToken</code> parameter is set to <code>null</code>.
