asami.durable.decoder — org.clojars.quoll/asami 2.3.2

Encodes and decodes data for storage. Clojure implementation

as-byte clj

(as-byte n)

bigdec-decoder clj

(bigdec-decoder ext paged-rdr pos)

bigint-decoder clj

(bigint-decoder ext paged-rdr pos)

blob-decoder clj

(blob-decoder ext paged-rdr pos)

bytes->long cljs

(bytes->long bytes)

bytes->str cljs

(bytes->str bytes)

date-decoder clj/s

(date-decoder ext paged-rdr pos)

decode-length clj/s≠

(decode-length ext paged-rdr pos)

clj

Reads the header to determine length. ext: if true (bit is 0) then length is a byte, if false (bit is 1) then length is in either a short or an int pos: The beginning of the data. This has skipped the type byte. returns: a pair of the header length and the data length.

cljs

Reads the header to determine length. ext: if 0 then length is a byte, if 1 then length is in either a short or an int

decode-length-node clj/s≠

clj

(decode-length-node data)

Reads the header to determine length. data: The complete buffer to decode, including the type byte. returns: the length, or a lower bound on the length

cljs

(decode-length-node b)

default-decoder clj/s

(default-decoder ext paged-rdr pos)

This is a decoder for unsupported data that has a string constructor

double-decoder clj

(double-decoder ext paged-rdr pos)

encapsulated-node? clj/s

(encapsulated-node? id)

extract-long clj

(extract-long id)

Extract a long number from an encapsulating ID

extract-node clj

(extract-node id)

extract-sstr clj

(extract-sstr id)

Extract a short string from an encapsulating ID

instant-decoder clj/s

(instant-decoder ext paged-rdr pos)

instant-length clj/s

keyword-decoder clj/s

(keyword-decoder ext paged-rdr pos)

lneg-bits clj

long-bytes-compare clj/s

(long-bytes-compare type-left left-header left-body left-object right-bytes)

Compare data from 2 values that are the same type. If the data cannot give a result then return 0. Operates on an array, expected to be in an index node.

long-decoder clj/s

(long-decoder ext paged-rdr pos)

long-nbit clj

map-decoder clj

(map-decoder ext paged-rdr pos)

A decoder for maps. Returns the map and the bytes read.

nybble-mask clj

partials-len clj

(partials-len bs)

(partials-len bs len)

Determine the number of bytes that form a partial character at the end of a UTF-8 byte array. The len argument is the defined length of the full string, but that may be greater than the bytes provided.

read-keyword clj/s

(read-keyword paged-rdr pos len)

read-long clj

(read-long paged-rdr pos len)

Raw reading of big-endian bytes into a long

read-object clj/s

(read-object paged-rdr pos)

Reads an object from a paged-reader, at id=pos

read-object-size clj

(read-object-size paged-rdr pos)

Reads an object from a paged-reader, at id=pos. Returns both the object and it's length.

read-str clj/s

(read-str paged-rdr pos len)

read-uri clj/s

(read-uri paged-rdr pos len)

seq-decoder clj

(seq-decoder ext paged-rdr pos)

This is a decoder for sequences of data. Use a vector as the sequence.

string-decoder clj/s

(string-decoder ext paged-rdr pos)

string-style-compare clj

(string-style-compare left-s right-bytes)

Compare the string form of an object with bytes that store the string form of an object

type-info clj/s≠

clj

(type-info b)

Returns the type information encoded in a header-byte

cljs

(type-info data)

type-nybble-shift clj

typecode->decoder clj/s≠

clj

Map of type codes to decoder functions. Returns object and bytes read.

cljs

Map of type codes to decoder functions

unencapsulate-id clj/s≠

clj

(unencapsulate-id id)

Converts an encapsulating ID into the object it encapsulates. Return nil if it does not encapsulate anything.

cljs

(unencapsulate-id x)

uri-decoder clj/s

(uri-decoder ext paged-rdr pos)

uuid-decoder clj/s

(uuid-decoder ext paged-rdr pos)

uuid-length clj/s

xsd-decoder clj

(xsd-decoder ext paged-rdr pos)
