extract-keys clj

(extract-keys map kmap)

(extract-keys map kmap keep)

Like rename-keys, except that it will not include keys not included in the replacement map or the keep vector in the returned map. Takes a map and a map of key to replacement key. Takes an optional third argument, which is a convenience vector of keys to keep without renaming.

(extract-keys {:a 1 :b 2 :c 3} {:b ::b} [:c]) => {::b 2 :c 3}

filter-vals clj

(filter-vals pred)

(filter-vals pred m)

Takes a predicate and a map, and returns a map containing only the keys for which (pred val) returns true. Returns a transducer when no input map is provided.

map-vals clj

(map-vals f)

(map-vals f m)

Returns a map consisting of the result of applying f to each value in m. Returns a transducer when no input map is provided.
