taxon-state: Last taxon state object from a get_* function call

Description

Last taxon state object from a get_* function call

Usage

taxon_last()
taxon_clear()

Value

taxon_last() returns an object of class taxon_state, the last one used, else NULL if none found. taxon_clear() clears the saved state

Details

• taxon_last(): get the last taxon_state object in use

• taxon_clear(): clear any data from last taxon_state object

The taxon_state object is an R6 object that holds data and methods used for keeping track of results gathered within a get_* function. You shouldn't create taxon_state R6 objects yourself.

Behaviors to be aware of:

• If a taxon_state object is not passed you don't need to worry about a previously run get_* function interfering with another get_* function call - you have to explicitly pass a taxon_state object to use taxon_state

• The passed in taxon_state object must have a $class matching that of the get_* function being called. For example, you can only pass a taxon_state with $class of gbifid to get_gbifid(), and so on.

• If you run taxon_clear() while a get* function is running, you may lose track of any state known to this package before it was cleared

See the internal method progressor for information on how we control messages in get* functions

Examples

# NOT RUN {
spp <- names_list("species", 3)
res <- get_gbifid(spp)
z <- taxon_last()
z
z$taxa_remaining()
z$taxa_completed()
z$count # active binding; no parens needed

# cleanup
taxon_clear()
# }
