org.soulspace.overarch.domain.model — org.soulspace.clj/overarch 0.9.0-SNAPSHOT

Functions for the definition and handling of the overarch model.

aggregable-relation? clj

(aggregable-relation? m r1 r2)

Returns true, if the relations r1 and r2 are aggregable.

all-elements clj

(all-elements m)

Returns a set of all elements.

build-id->parent clj

(build-id->parent coll)

(build-id->parent m p coll)

Returns a map of child id to parent element for the elements in coll.

build-registry clj

(build-registry elements)

Returns a map with the original elements and a registry by id for lookups.

The map has the following shape:

:elements -> the given data :registry -> a map from id to element :parents -> a map from id to parent element :referrer -> a map from id to set of relations where the id is the referrer (:from) :referred -> a map from id to set of relations where the id is referred (:to)

children clj

(children m e)

Returns the children of the element e.

get-model-element clj

(get-model-element m id)

Returns the model element with the given id.

get-model-elements clj

(get-model-elements m)

Returns the collection of model elements.

get-parent-element clj

(get-parent-element m e)

Returns the parent of the element e.

id->element clj

(id->element)

(id->element acc)

(id->element acc e)

Adds the association of the id of the element e to the map acc.

id->parent clj

(id->parent)

(id->parent acc)

(id->parent [res p] e)

Adds the association from the id of element e to the parent p to the map acc.

id-set clj

(id-set coll)

Returns a set of id's for the elements in coll.

model-elements clj

(model-elements coll)

Filters the given collection of elements coll for model elements.

parent clj

(parent m e)

Returns the parent of the element e.

referred-id->rel clj

(referred-id->rel)

(referred-id->rel acc)

(referred-id->rel acc r)

Adds the relation r to the set associated with the id of the :to reference in the map acc.

referrer-id->rel clj

(referrer-id->rel)

(referrer-id->rel acc)

(referrer-id->rel acc e)

Adds the relation r to the set associated with the id of the :from reference in the map acc.

related clj

(related m coll)

Returns the related elements for the given collection of relations

related-nodes clj

(related-nodes m coll)

Returns the set of nodes of the model m that are part of at least one relation in the coll.

relations-of-nodes clj

(relations-of-nodes m coll)

Returns the relations of the model m connecting nodes from the given collection of model nodes.

resolve-element clj

(resolve-element m e)

Resolves the model element for the ref e.

resolve-ref clj

(resolve-ref m r)

Resolves the model element for the ref r.

traverse clj

(traverse select-fn step-fn coll)

Traverses the coll of elements and returns the elements selected by the select-fn and transformed by the step-fn.

select-fn - a predicate on the current element step-fn - a function with three signatures [], [acc] and [acc e]

The no args signature of the step-fn should return an empty accumulator, the one args signature extracts the result from the accumulator on return and the 2 args signature receives the accumulator and the current element and should add the transformed element to the accumulator.
