ComponentGraphUpdater ​

Helper to validate if the interfaceDefinition is still visible/invisible derived As InterfaceSpecificationVersion can be derived in a circle, this helper maintains a set of already visited nodes to identify circles A InterfaceSpecificationVersion is only derived if a path the origial source is identified

Cache used to ensure that only one instance of each Node is loaded by the algorithm

Nodes which should be deleted

Nodes which are updated and need to be saved This may contain nodes also present in deletedNodes

Helper for updating aggregated issues

Nodes which are updated and need to be saved Does not include any deleted nodes

derives InterfaceSpecificationVersion for a specified ComponentVersion derives via all incoming Relation Performs a transitive graph update

Updates the InterfaceSpecificationVersion derivation for a single Relation Does NOT perform a graph update Only derives additional InterfaceSpecificationVersion, but does not ensure that all already existing InterfaceDefinition on the end of the relation are still derived

Handles the graph update (InterfaceSpecificationVersion derivation) after a Relation has been created / updated Does NOT validate if the Relation can still exist Only ensures derivation of additional InterfaceSpecificationVersion, but does not validate that no longer derived InterfaceSpecificationVersion are updated/removed

Adds an InterfaceSpecificationVersion to a ComponentVersion Updates the InterfaceDefinition and creates it if necessary

Creates an Interface for an InterfaceDefinition, which has become visible

Called after a Relation has been created Handles the derivation of InterfaceSpecificationVersions

Deletes a Component

Deletes a ComponentVersion

Deletes an Interface Handles deletion of associated IntraComponentDependencyParticipants and, if necessary, IntraComponentDependencySpecifications

Deletes an InterfaceDefinition

Deletes an InterfaceSpecification

Deletes an InterfaceSpecificationVersion

Deletes a IntraComponentDependencySpecification and all its associated IntraComponentDependencyParticipants

Deletes a Relation

Derives an interfaceSpecificationVersion via a relation to a componentVersion Does not perform a graph update

Helper to

Finds all RelationPartners that are connected to a RelationPartner via incoming Relations. Also considers Interfaces of ComponentVersions.

Finds all RelationPartners that are connected to a RelationPartner via outgoing Relations. Also considers Interfaces of ComponentVersions.

Gets or creates if non-existing a InterfaceDefinition for a ComponentVersion and an InterfaceSpecificationVersion If created, adds it to the updated nodes

Handles the update of an InterfaceDefinition. Creates / deletes the associated Interface if necessary Deletes the provided InterfaceDefinition if necessary

Locks all incoming and outgoing RelationPartners of a RelationPartner

Removes an InterfaceSpecificationVersion from a ComponentVersion Updates the InterfaceDefinition and deletes it if necessary

Deletes all deletedNodes and saves all updatedNodes to the database

Called after the template of a Component has been updated Validates InterfaceDefinitions and Relations Does NOT handle updating SubTemplates

Called after the template of an InterfaceSpecification Validates InterfaceDefinitions and Relations oes NOT handle updating SubTemplates

Called after a template of a Relation has been updated Updates the derivation of InterfaceSpecificationVersions Does not validate if the Relation can still exist

Validates InterfaceDefinitions on componentVersion Removes / updates those if InterfaceSpecificationVersions are no longer derived Performs a graph update

Called after the template of a Component or an InterfaceSpecification was updated Validates that interfaceDefinition can still be present on the associated ComponentVersion, and if not, removes it (maybe partially) Does NOT perform any validation of the graph

Validates InterfaceDefinitions on a ComponentVersion Removes / updates those if InterfaceSpecificationVersions are no longer derived Uses CircularDerivationChecker to remove despite circular derivation Performs a graph update

Validates InterfaceDefinitions on ComponentVersions incoming-related to the provided componentVersion Removes / updates those if InterfaceSpecificationVersions are no longer derived Performs a graph update

Validates if a Relation an still exist after the template of either its start or end has been updated If not, deletes the relation and handles the resulting graph update

Validates both incoming and outgoing relations of a RelationPartner after the template of said RelationPartner has been updated Deletes Relations if necessary, and handles updates to InterfaceSpecificationVersion derivation Does NOT validate InterfaceSpecificationVersion derivation independent of Relation deletion
