public class ITER_HTTPGet extends fr.mines_stetienne.ci.sparql_generate.iterator.IteratorStreamFunctionBase
Iterator function iter:HTTPGet binds the responses of regular GET operations to a HTTP(s) URL.

See Live example

  • Param 1: (a URI or String) the Web URI where regular GET operations are operated;
  • Param 2: (a positive Integer) the number of seconds between successive calls to the Web API;
  • Param 3 (optional): the total number of calls to make (a positive Integer). If not provided, the iterator never ends.

Example:

The clause

ITERATOR iter:HTTPGet(<https://example.org/room1/temperature>,60) AS ?temperature

will fetch the temperature of room 1 every 60 seconds, indefinetely.
