clojure.algo.generic.comparison — org.clojure/algo.generic 0.1.3

Generic comparison interface This library defines generic versions of = not= < > <= >= zero? as multimethods that can be defined for any type. Of the greater/less-than relations, types must minimally implement >.

< clj multimethod

(< x)

(< x y)

(< x y & more)

Return true if each argument is smaller than the following ones. The minimal implementation for type ::my-type is the binary form with dispatch value [::my-type ::my-type]. A default implementation is provided in terms of >.

<= clj multimethod

(<= x)

(<= x y)

(<= x y & more)

Return true if each arguments is smaller than or equal to the following ones. The minimal implementation for type ::my-type is the binary form with dispatch value [::my-type ::my-type]. A default implementation is provided in terms of >.

= clj multimethod

(= x)

(= x y)

(= x y & more)

Return true if all arguments are equal. The minimal implementation for type ::my-type is the binary form with dispatch value [::my-type ::my-type].

> clj multimethod

(> x)

(> x y)

(> x y & more)

Return true if each argument is larger than the following ones. The minimal implementation for type ::my-type is the binary form with dispatch value [::my-type ::my-type].

>= clj multimethod

(>= x)

(>= x y)

(>= x y & more)

Return true if each argument is larger than or equal to the following ones. The minimal implementation for type ::my-type is the binary form with dispatch value [::my-type ::my-type]. A default implementation is provided in terms of <.

max clj

(max x)

(max x y)

(max x y & more)

Returns the greatest of its arguments. Like clojure.core/max except that is uses generic comparison functions implementable for any data type.

min clj

(min x)

(min x y)

(min x y & more)

Returns the least of its arguments. Like clojure.core/min except that is uses generic comparison functions implementable for any data type.

neg? clj multimethod

(neg? x)

Return true of x is negative.

not= clj

(not= & args)

Equivalent to (not (= ...)).

pos? clj multimethod

(pos? x)

Return true of x is positive.

zero? clj multimethod

(zero? x)

Return true of x is zero.
