aritiesclj
(arities f)Returns a vector of numbers describing the arities of (multi-bodied):
- anonymous functions like
#()and(fn []). - defined functions like
mapor#'+. - macros, by passing a var like
#'->.
Includes ##Inf (Double/POSITIVE_INFINITY) if the function/macro
is variadic.
Returns a vector of numbers describing the arities of (multi-bodied): - anonymous functions like `#()` and `(fn [])`. - defined functions like `map` or `#'+`. - macros, by passing a var like `#'->`. Includes `##Inf` (`Double/POSITIVE_INFINITY`) if the function/macro is variadic.
fake-aritiesclj
(fake-arities arity f)Returns a function g wrapping f so that (arities g)
returns arity instead of f's'original arity.
arity can be a number or a sequence of numbers.
Uses ##Inf (Double/POSITIVE_INFINITY) to signify a variadic
arity.
Note that this function is orthogonal to Clojure's native arity
checks and its only intended use is to force the return value of
arities.
Returns a function `g` wrapping `f` so that `(arities g)` returns `arity` instead of `f`'s'original arity. `arity` can be a number or a sequence of numbers. Uses `##Inf` (`Double/POSITIVE_INFINITY`) to signify a variadic arity. Note that this function is orthogonal to Clojure's native arity checks and its only intended use is to force the return value of [[arities]].
max-arityclj
(max-arity f)Returns the maximum arity of f with the same semantics as
arities.
Returns the maximum arity of `f` with the same semantics as `arities`.
min-arityclj
(min-arity f)Returns the minimum arity of f with the same semantics as
arities.
Returns the minimum arity of `f` with the same semantics as `arities`.
