Prismatic Schema type definitions

CharVec clj

An ordered sequence of characters of indeterminate length.

DatomMap clj

The Clojure map representation of a Datom.

Eid clj

Each entity in the DB is uniquely specified its Entity ID (EID). Indeed, allocation of a unique EID is what 'creates' an entity in the DB.

EnliveNode clj/s

An Enlive tree node

EntitySpec clj

An EntitySpec is used to uniquely specify an entity in the DB. It consists of either an EID or a LookupRef.

Fn clj/s

HttpRequest clj

KeyMap clj/s

List clj/s

An ordered sequence of items of indeterminate length (synonymous for Vec).

LookupRef clj

If an entity has an attribute with either :db.unique/value or :db.unique/identity, that entity can be uniquely specified using a lookup-ref (LookupRef). A lookup-ref is an attribute-value pair expressed as a tuple: [ <attribute> <value> ]

Map clj/s

MapEntry clj/s

MapList clj/s

Pair clj/s

Quad clj/s

Set clj/s

Either a Clojure hash-set or a java.util.HashSet

Single clj/s

Triple clj/s

Tuple clj/s

A specific type of sequential collection, typically a vector of constant length where each element has a pre-defined interpretation.

TupleList clj/s

A sequence of tuples (typically a vector of vectors)

TupleMap clj/s

TupleMaps clj/s

TupleSet clj/s

The result of any Datomic using the Entity API is logically a hash-set of tuples (vectors). The contents and order of each tuple is determined by the find clause:

 ----- query -----                         ----- tuples -----

(d/q '{:find [?e ?name ?age] ...) -> [?e ?name ?age]

Vec clj/s

An ordered sequence of items of indeterminate length (synonymous for List).
