The generic function
remove-items
removes from
the
collection
collection
those items determined by
list-or-predicate
.
If list-or-predicate is list, then the items removed are those matching some element of list-or-predicate , compared by the test-function of collection . Otherwise, the items removed are those for which the function list-or-predicate returns true.
This is logically equivalent to recalculating the collection items and then calling
(setf collection-items)
. However,
remove-items
is more efficient and causes less flickering on screen.
remove-items
can only be used when the collection has the default
items-get-function
svref
.
