List all object ids for a resource on a ArcGIS Enterprise MapServer

Source: R/list_object_ids.R
list_object_ids.Rd

This function lists all object ids for a given resource on a ArcGIS Enterprise.

Usage

list_object_ids(source, resource = get_default_resource(source))

Arguments

source

(Required) Character string indicating the source of the data to fetch. Currently supported data sources: rato will fetch RATO data and wfl will fetch data from the province of West Flanders.

resource

The resource to query. Defaults to the default resource for the given source.

Value

Integer vector of (all) object ids.

Fetching all objects

Downloading all data for a resource consists of a two step process. First all object ids for a resource are queried. Then the objects are fetched from that resource by their id.

Caching

The returned id's are cached by default, but this can be overwritten by calling memoise::forget(list_object_ids) which will remove the cache and ensure the next call queries the database (but will reinstate the cache for any follow up calls).
