io.randomseed.bankster.util — io.randomseed/bankster 1.2.13

Support functions and macros.

bytes-concat clj

(bytes-concat)

(bytes-concat bary)

(bytes-concat bary & byte-arys)

bytes-to-string clj

(bytes-to-string b)

Converts bytes into a string

bzero clj

char-ranges->set clj

(char-ranges->set & ranges)

Returns a set of characters defined as a collection of collections with start and stop character, e.g.: [\A \Z][\0 \9]

count-digits clj

(count-digits n)

current-thread clj

(current-thread)

current-thread-id clj

(current-thread-id)

current-thread-name clj

(current-thread-name)

ensure-keyword clj

(ensure-keyword id)

ensure-keyword-having-ns clj

(ensure-keyword-having-ns id ns)

gen-digits clj

(gen-digits num)

(gen-digits num rng)

Generates the given number of random digits and converts all into a single string. When the second argument is present it should be an instance of random number generator used to get the digits.

get-rand-int clj

(get-rand-int n)

(get-rand-int n rng)

Like rand-int but optionally uses random number generator.

get-rand-nth clj

(get-rand-nth v)

(get-rand-nth v rng)

Returns a random element of the given vector. When the second argument is present it should be an instance of random number generator used to get the random position.

inferred-contains? clj

(inferred-contains? coll k)

Just like the contains? but if the keyword is namespace-qualified it also checks if the collection contains the same keyword as its key but without a namespace.

inferred-get clj

(inferred-get coll k)

(inferred-get coll k default)

Just like the get function but if the keyword is namespace-qualified it first attempts to look for the value associated with it. If that fails it uses the variant of the keyword without any namespace.

is clj macro

(is pred val & body)

is-not clj macro

(is-not pred val & body)

juxt-seq clj

(juxt-seq & functions)

Like juxt but returns a lazy sequence.

lazy-iterator-seq clj

(lazy-iterator-seq coll)

(lazy-iterator-seq coll iter)

Returns a lazy sequence as an interface to the given iterable Java object.

must-have-ns clj

(must-have-ns id ns)

ns-infer clj

(ns-infer ns-name k)

(ns-infer ns-name k use-infer)

Takes a string of namespace name and a keyword. If the given keyword is not namespace-qualified it returns a new keyword with the given namespace added. If the given keyword is already equipped with a namespace it returns it.

random-digits-len clj

(random-digits-len x iteration shrink-now)

(random-digits-len x iteration shrink-now rng)

For 0 or 1 it returns its argument. For other positive numbers it returns a random natural number from 1 to this number (inclusive) in 50% cases. In other 50% cases it returns its argument.

replace-in-set clj

(replace-in-set s old-val new-val)

some-string clj

(some-string s)

text-to-bytes clj

(text-to-bytes t)

to-bytes clj

(to-bytes obj)

to-long clj

(to-long s default)

try-null clj macro

(try-null & body)

Evaluates body and if NullPointerException exception is caught it returns nil. Otherwise it returns the value of last expression in the body.

try-parse-int clj

(try-parse-int s)

Returns integer from an object or nil if the given object does not contain valid integer.

try-parse-long clj

(try-parse-long s)

Returns long from an object or nil if the given object does not contain valid long.

try-upper-case clj

(try-upper-case s)

uuid clj

(uuid s)

when-not-empty clj macro

(when-not-empty val & body)

Evaluates body when the given value is a non-empty collection.

with-not-empty clj

(with-not-empty obj)

Returns the collection if it's not empty. Otherwise returns nil.
