Last taxon state object from a get_*
function call
Description
Last taxon state object from a get_*
function call
Usage
taxon_last()
taxon_clear()
Details
-
taxon_last()
: get the lasttaxon_state
object in use -
taxon_clear()
: clear any data from lasttaxon_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 runget_*
function interfering with anotherget_*
function call - you have to explicitly pass ataxon_state
object to usetaxon_state
The passed in
taxon_state
object must have a$class
matching that of theget_*
function being called. For example, you can only pass ataxon_state
with$class
ofgbifid
toget_gbifid()
, and so on.If you run
taxon_clear()
while aget*
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
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
