missinterpret.flows.schema — io.github.missinterpret/flows 1.0.5

add-meta clj

(add-meta o m)

Adds the map keys to the existing metadata of the object.

closed? clj

(closed? schema)

compatible? clj

(compatible? src dest)

Does a value which conforms to the source schema validate against the destination schema?

NOTE: The source schema MUST be able to generate a value via mg/generate.

empty-trace clj

(empty-trace)

extract-integrity clj

(extract-integrity wf)

If the workflow's metadata contains the schema integrity it is returned. Otherwise nil.

in-schema clj

(in-schema {:schema/keys [in]})

integrity clj

(integrity wf)

io clj

(io o)

Returns the input/output schema of an object when added as metadata that matches the missinterpret.flows.spec/Defn* schema. (i.e. {:schema/in, :schema/out})

Impl Note:

When defn evaluates it generates a class with name as per (munge fn-symbol). The demunge function will reverse this operation.

From the class name of a Fn object we can get the symbol back, and from the symbol, we look up the var which has the metadata attached to it.

lowest-rank clj

(lowest-rank chain)

Returns the lowest ranking in the chain of flow integrity entities.

For example: [:strict :conflict] would return :conflict

NOTE: Skips :no-schema when evaluating

map-schema? clj

(map-schema? schema)

merge-trace clj

(merge-trace trace {:keys [no-schema runtime passed conflict]})

merge-traces clj

(merge-traces chain)

Collects and merges the :no-schema, runtime, passed and conflict traces from the chain.

rank clj

(rank score)

rank-flow clj

(rank-flow chain {:flow/keys [id] :as flow})

score clj

(score rank)

Converts a rank into an integer that preserves the ordering.

trace-key clj

(trace-key chain kw)

Traces the origin on the keyword to a previous entity in the chain.

It searches by working backward from the last entity in the chain applying the heuristic:

• Entity does not have a schema - skipped
• Entity has a closed schema before key is found -> {:conflict #{ID-of-entity}} Note this does not conform to the general trace schema
• A schema of an entity has the keyword -> {:passed {KW ID}}
• The end of the chain is reached without finding the keyword -> {:runtime #{kw}}

underspecified? clj

(underspecified? integrity)

Does the chain contain one non no-schema integrity rank?

unspecified? clj

(unspecified? chain)

Are all links in the chain :no-schema?

with-io clj

(with-io o m)

Attaches the io schema to the object
