Description
The scrapes method returns a list of all defined
resources for the given data object that are scrapeable
i.e. that can be extracted from some external data
source.Details
The names of this list are suitable parameters to the
scrape method. The elements of the list are
themselves lists that contain parameters for
dbWriteTable: savemode ("w" for replacing, "u" for
updating), uniq (columns names which may appear only
once) dates and timestamps (column names that are
converted to character before writing to and after
loading from the datastore).
By default (XData), scrapes returns an empty list.
Inherited classes should override this method if
necessary.References
