Functions to run rules until completion.

execute clj/s≠

(execute rules db-store)

clj

Inputs: [rules :- #:s{Str DynamicRule} db-store :- StorageType] Returns: [(s/one StorageType "Final value of storage") (s/one #:s{Str s/Num} "Map of rule name to execution count")]

Executes a program. Data is retrieved from and inserted into db-store.

cljs

Inputs: [rules :- {s/Str DynamicRule} db-store :- StorageType] Returns: [(s/one StorageType "Final value of storage") (s/one {s/Str s/Num} "Map of rule name to execution count")]

Executes a program. Data is retrieved from and inserted into db-store.

extract-dirty-pattern clj/s

(extract-dirty-pattern [p status-atom])

Inputs: [[p status-atom] :- StatusMapEntry] Returns: (s/maybe ss/EPVPattern)

Takes a key and value pair (from a status map) and determines if the value (a ConstraintData) is marked dirty. If it is dirty, then return the key (an EPVPattern).

initialize-rules clj/s≠

(initialize-rules rules)

clj

Inputs: [rules :- #:s{Str Rule}] Returns: #:s{Str DynamicRule}

Takes rules with calculated dependencies, and initializes them

cljs

Inputs: [rules :- {s/Str Rule}] Returns: {s/Str DynamicRule}

Takes rules with calculated dependencies, and initializes them

mark-rule-cleaned-with-latest-count! clj/s≠

(mark-rule-cleaned-with-latest-count! dirty-patterns counted-set status)

clj

Inputs: [dirty-patterns :- [ss/EPVPattern] counted-set :- #:ss{EPVPattern ss/EPVPattern} status :- StatusMap]

Reset the pattern status, making it clean. Uses meta from resolve-count (above). Result should be ignored.

cljs

Inputs: [dirty-patterns :- [ss/EPVPattern] counted-set :- {ss/EPVPattern ss/EPVPattern} status :- StatusMap]

Reset the pattern status, making it clean. Uses meta from resolve-count (above). Result should be ignored.

resolve-count clj/s

(resolve-count storage status p)

Inputs: [storage :- StorageType status :- StatusMap p :- ss/EPVPattern] Returns: (s/maybe ss/EPVPattern)

Resolve a pattern against storage, and set the :resolution meta data if the result is different from the last resolution. Requires a status map in order to lookup the last-count.

run clj/s≠

(run config {:keys [rules axioms]})

clj

Inputs: [config :- #:s{Keyword s/Any} {:keys [rules axioms]} :- Program] Returns: [(s/one StorageType "Resulting data store") (s/one #:s{Str s/Num} "Execution stats") (s/one (s/maybe [s/Any]) "Delta IDs")]

Runs a program against a given configuration

cljs

Inputs: [config :- {s/Keyword s/Any} {:keys [rules axioms]} :- Program] Returns: [(s/one StorageType "Resulting data store") (s/one {s/Str s/Num} "Execution stats") (s/one (s/maybe [s/Any]) "Delta IDs")]

Runs a program against a given configuration

schedule-downstream-queue clj/s≠

(schedule-downstream-queue rules remaining-queue downstream)

clj

Inputs: [rules :- #:s{Str DynamicRule} remaining-queue :- PQueueType downstream :- [RulePatternPair]]

Adds all downstream rules to the queue. The queue will adjust order according to salience, if necessary. Also marks relevant patterns in the downstream rule bodies as dirty.

cljs

Inputs: [rules :- {s/Str DynamicRule} remaining-queue :- PQueueType downstream :- [RulePatternPair]]

Adds all downstream rules to the queue. The queue will adjust order according to salience, if necessary. Also marks relevant patterns in the downstream rule bodies as dirty.
