clj

Encodes and decodes data for storage. Clojure implementation

cljs

Encodes and decodes data for storage. ClojureScript implementation

*current-offset* clj

*entity-offsets* clj

*number-buffer* clj

*number-bytes* clj

byte-array cljs

(byte-array size-or-seq)

comparable-map clj

(comparable-map m)

Converts a map into a vector of the equivalent data, so it may be compared

concat-bytes clj

(concat-bytes bas)

Takes multiple byte arrays and returns an array with all of the bytes concattenated

constant-length? clj

The set of types that can be encoded in a constant number of bytes. Used for homogenous sequences.

empty-bytes clj

encapsulate-id cljs

(encapsulate-id x)

encapsulate-long clj

(encapsulate-long l)

Encapsulates a long value. If the long is too large to be encapsulated, then return nil.

encapsulate-sstr clj

(encapsulate-sstr s type-mask)

Encapsulates a short string. If the string cannot be encapsulated, then return nil.

FlatFile clj/s≠ protocol

body clj/s

(body this)

Returns a byte array containing the encoded data

comparable clj/s

(comparable this)

Returns a version of this data that can be compared

header clj/s

(header this len)

Returns a byte array containing a header

encapsulate-id clj

(encapsulate-id this)

Returns an ID that encapsulates the type

general-header clj/s

(general-header t len)

Takes a type number and a length, and encodes to the general header style. Lengths 0-255 [2r1110tttt length] Lengths 256-32k [2r1111tttt (low-byte length) (high-byte length)] Lengths 32k-2G [2r1111tttt (byte0 length) (byte1 length) (byte2 length) (byte3 length)]

map-body clj

(map-body this)

Common function for encoding the body of the various map types

map-header clj

(map-header this len)

Common function for encoding the header of the various map types

max-short-len clj

max-short-long clj

milli-nano clj

Number of nanoseconds in a millisecond

min-short-long clj

n-byte-number clj

(n-byte-number n x)

Returns an array of n bytes representing the number x. Must be initialized for the current thread.

num-bytes clj

(num-bytes n)

Determines the number of bytes that can hold a value. From 2-4 tests, this preferences small numbers.

registered-xsd-types clj

A map of types to encoding functions

str-constructor? clj

(str-constructor? c)

Tests if a class has a constructor that takes a string

to-bytes clj/s

(to-bytes o)

Returns a tuple of byte arrays, representing the header and the body

to-counted-bytes clj

(to-counted-bytes o)

Returns a tuple of byte arrays, representing the header and the body

type->code clj/s

type-code clj/s

(type-code o)

Returns a code number for an object

type-compare clj

(type-compare a b)

Provides a regular comparison of objects of potentially different types

zero-array clj

A single element byte array containing 0
