Direct Method

empty-p

Returns t if there are no items in the container.

iterate-container
iterate-nodes

Applies function to each node in the container. If the container doesn't have nodes, then this is...

Other Method

Returns the item in items with the 'best' value of function where
'best' is determined by test. Y...

predicate. Predicate should be a funct...

finish

Tell Lisp that you are done with this iterator. Further calls to current-element, etc. will have ...

first-element
insert-new-item

Adds item to the container unless it is already there

insert-sequence

Adds each item in the sequence to the container in an
upspecified order.

iteratable-p

Returns true if thing knows how to iterate-nodes.

make-iterator
move
move-forward-to-next-element
move-p
next-element
nth-element

Returns the nth element in the container's 'natural' order.

print-container

Prints the contents of container (using PRINT). Returns the container.

print-iterator
reduce-container
reduce-elements
reduce-nodes
remove-items-if

Removes items from a container that satisfy the test. The
container is returned.

reset
search-for-element
search-for-item

Hunt for the item in the container. Key and Test
are as in member.

search-for-match

Hunt for an item in the container that satisfies
the predicate. Key is as in count-if.

Returns the first item in the container for which predicate
holds. Predicate should be a function...
