get method
Gets the specified routine resource by routine ID.
Request parameters:
projectId - Required. Project ID of the requested routine
Value must have pattern ^\[^/\]+$.
datasetId - Required. Dataset ID of the requested routine
Value must have pattern ^\[^/\]+$.
routineId - Required. Routine ID of the requested routine
Value must have pattern ^\[^/\]+$.
readMask - If set, only the Routine fields in the field mask are
returned in the response. If unset, all Routine fields are returned.
$fields - Selector specifying which fields to include in a partial
response.
Completes with a Routine.
Completes with a commons.ApiRequestError if the API endpoint returned an error.
If the used http.Client completes with an error when making a REST call,
this method will complete with the same error.
