->coll clj

(->coll x)

Coerces x into a collection - if x is already a collection it is returned, otherwise a singleton collection containing x.

assoc-if clj

(assoc-if m condition k v)

Associates v with the key k in the associative structure m if condition is truthy, otherwise returns m.

eager-split-at clj

(eager-split-at n xs)

Version of split-at that eagerly consumes the first n items of the source sequence. split-at returns two lazy sequences which means the head of the input sequence must be retained if. Usually the prefix is the shorter sequence so this function eagerly constructs the prefix sequence and leaves the remainder to be lazily evaluated.

equals-ignore-case? clj

(equals-ignore-case? s1 s2)

Whether two string are equal ignoring case differences. Nil references are considered equal.

filter-values clj

(filter-values pred m)

Filters a map given a predicate on the values.

get-declared-method clj

(get-declared-method cls method-name arg-types)

hex-digits clj

ignore-exceptions clj macro

(ignore-exceptions & body)

invoke-method clj

(invoke-method method args)

(invoke-method method receiver args)

Invokes the given Method instance with the given arguments and receiver if one is specified. Unwraps the inner exception if an InvocationTargetException is thrown.

liberal-concat clj

(liberal-concat & seqs)

Version of concat which avoids holding onto the heads of the argument functions

liberal-mapcat clj

(liberal-mapcat f s)

Version of mapcat which avoids holding onto the heads of the generated subsequences.

map-keys clj

(map-keys f m)

Transforms the keys in a map according to the given function.

map-values clj

(map-values f m)

Transforms the values in a map according to the given function.

non-negative? clj

(non-negative? x)

Whether the given value is a non-negative number.

normalise-uri clj multimethod

Does path and scheme-based normalisation for HTTP and HTTPS URIs, path-based normalisation for other URIs.

owning-iterator clj

(owning-iterator source factory-fn)

Returns an iterator which takes ownership of source and uses it to construct an inner iterator via factory-fn. Automatically closes source when the inner iterator is exhausted, or if an exception is thrown during the iteration.

parse-hex-string clj

(parse-hex-string string-value)

Parses a hex string into a byte array

partition-keys clj

(partition-keys source-map ref-keys)

Splits a source map into two sub-maps - the first contain the keys in both source-map and ref-keys, the second contains the keys in source-map which do not exist in ref-keys.

percent-decode clj

(percent-decode s)

Decodes a percent-encoded string. Assumes all characters in the input are in the ASCII range. Throws an IllegalArgumentException if the input is malformed.

percent-encode clj

(percent-encode s)

(percent-encode s charset)

Percent-encodes the bytes in the given string.

percent-unreserved-chars clj

remove-fragment clj

(remove-fragment uri)

Sets the fragment on a URI to nil.

resolve-uri clj

(resolve-uri base-uri rel)

Resolves the given string against a base URI. This differs from java.net.URI/resolve in that empty strings are ignored and return the base URI is returned unaltered.

select-keys-as clj

(select-keys-as m key-mapping)

Selects keys from the source map m, renaming them to the mapped keys in the result map e.g.

(select-keys-as {"foo" 1 "bar" 2} {"foo" :a "quux" :b}) => {:a 1}

set-fragment clj

(set-fragment uri fragment)

Sets the fragment on a URI to the given value.

to-hex-string clj

(to-hex-string arr)

Returns the hex representation of a byte array
