IWalk clj protocol

-walk clj

(-walk coll f)

If coll is a collection, applies f to each element of the collection and returns a collection of the results, of the same type and order as coll. If coll is not a collection, returns it unchanged. "Same type" means a type with the same behavior. For example, a hash-map may be returned as an array-map, but a a sorted-map will be returned as a sorted-map with the same comparator.

maybe-meta clj

(maybe-meta o)

meta? clj

(meta? o)

postwalk clj

(postwalk f form)

Performs a depth-first, post-order traversal of form. Calls f on each sub-form, uses f's return value in place of the original. Recognizes all Clojure data structures. Consumes seqs as with doall.

preserving-meta clj

(preserving-meta o o')

preserving-postwalk clj

(preserving-postwalk f form)

preserving-walk clj

(preserving-walk inner outer form)

walk clj

(walk inner outer form)

Traverses form, an arbitrary data structure. inner and outer are functions. Applies inner to each element of form, building up a data structure of the same type, then applies outer to the result. Recognizes all Clojure data structures. Consumes seqs as with doall.
