Description

Retrieves the names of all crawler resources in this Amazon Web Services account, or the resources with the specified tag. This operation allows you to see which resources are available in your account, and their names.

This operation takes the optional Tags field, which you can use as a filter on the response so that tagged resources can be retrieved as a group. If you choose to use tags filtering, only resources with the tag are retrieved.

Synopsis

Constructors

ListCrawlers'
Fields nextToken :: Maybe Text A continuation token, if this is a continuation request. maxResults :: Maybe Natural The maximum size of a list to return. tags :: Maybe (HashMap Text Text) Specifies to return only these tagged resources.

newListCrawlers :: ListCrawlers Source #

Create a value of ListCrawlers with all optional fields omitted.

Use generic-lens or optics to modify other optional fields.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:

$sel:nextToken:ListCrawlers', listCrawlers_nextToken - A continuation token, if this is a continuation request.

$sel:maxResults:ListCrawlers', listCrawlers_maxResults - The maximum size of a list to return.

$sel:tags:ListCrawlers', listCrawlers_tags - Specifies to return only these tagged resources.

Request Lenses

listCrawlers_nextToken :: Lens' ListCrawlers (Maybe Text) Source #

A continuation token, if this is a continuation request.

listCrawlers_maxResults :: Lens' ListCrawlers (Maybe Natural) Source #

The maximum size of a list to return.

listCrawlers_tags :: Lens' ListCrawlers (Maybe (HashMap Text Text)) Source #

Specifies to return only these tagged resources.

Destructuring the Response
