Request Syntax

response_iterator = paginator.paginate(
    MasterRegion='string',
    FunctionVersion='ALL',
    PaginationConfig={
        'MaxItems': 123,
        'PageSize': 123,
        'StartingToken': 'string'
    }
)

Parameters:

• MasterRegion (string) – For Lambda@Edge functions, the Amazon Web Services Region of the master function. For example, us-east-1 filters the list of functions to include only Lambda@Edge functions replicated from a master function in US East (N. Virginia). If specified, you must set FunctionVersion to ALL.

• FunctionVersion (string) – Set to ALL to include entries for all published versions of each function.

• PaginationConfig (dict) –

  A dictionary that provides parameters to control pagination.

  • MaxItems (integer) –

    The total number of items to return. If the total number of items available is more than the value specified in max-items then a NextToken will be provided in the output that you can use to resume pagination.

  • PageSize (integer) –

    The size of each page.

  • StartingToken (string) –

    A token to specify where to start paginating. This is the NextToken from a previous response.
