Package org.gcube.informationsystem.resourceregistry.persistence

Interface ERManagement

All Known Implementing Classes:
ConsistsOfManagement, EntityManagement, FacetManagement, IsRelatedToManagement, RelationManagement, ResourceManagement
public interface ERManagement
Contract shared by the OrientDB persistence classes for both Entity Relationship categories — Entities (Resource/Facet, via EntityManagement) and Relations (ConsistsOf/IsRelatedTo, via RelationManagement). Covers Avalanche Effect context-membership propagation (addToContext(UUID) / removeFromContext(UUID), with cycle-prevention via the shared getVisited() set), and the read-path knobs (contexts-map membership view, hierarchical/active-only-hierarchical reads, context inclusion) that the Instances Policy Enforcement Point configures before delegating to a concrete implementation.

  • Method Details

    • getPropagationMode

      org.gcube.informationsystem.resourceregistry.api.rest.PropagationMode getPropagationMode()
      Returns the propagation mode for context sharing.
      Returns:
      the propagation mode

    • setPropagationMode

      void setPropagationMode(org.gcube.informationsystem.resourceregistry.api.rest.PropagationMode propagationMode)
      Sets the propagation mode for context sharing.
      Parameters:
      propagationMode - the propagation mode to set

    • isForceAddToContext

      boolean isForceAddToContext()
      Gets whether the operation should force add to context even if the instance is not in source context.
      Returns:
      true if force add, false otherwise

    • setForceAddToContext

      void setForceAddToContext(boolean forceAddToContext)
      Sets whether the operation should force add to context even if the instance is not in source context.
      Parameters:
      forceAddToContext - true to force add, false otherwise

    • getAffectedInstances

      Map<UUID,org.gcube.com.fasterxml.jackson.databind.JsonNode> getAffectedInstances()
      Returns the map of affected instances during the operation, mapped by their UUID to their JSON representation.
      Returns:
      the map of affected instances

    • setWorkingContext

      void setWorkingContext(UUID contextUUID)
      Sets the Context the instance is looked up in, in place of the token Context: the Context a Remove from Context acts on, and with isHierarchical() its descendants too.
      Parameters:
      contextUUID - the UUID of the Context, or null for the token Context

    • setSourceInstanceEnvironment

      void setSourceInstanceEnvironment(InstanceEnvironment source)
      Sets the source InstanceEnvironment used to evaluate addToContext
      Parameters:
      source - the source security context

    • getSourceInstanceEnvironment

      InstanceEnvironment getSourceInstanceEnvironment()
      Returns the source InstanceEnvironment used to evaluate context sharing operations.
      Returns:
      the source instance environment

    • setVisited

      void setVisited(Set<UUID> visited)
      Sets the shared, mutable set of UUIDs (entities and relations alike) already visited during the current addToContext(UUID) cascade. Checked and populated unconditionally by every ERManagement instance in the cascade, regardless of PropagationMode — cycle-safety is kept orthogonal to whatever each mode otherwise decides about re-visiting an already-present instance, so it does not need to be re-derived if propagation semantics change later.
      Parameters:
      visited - the shared visited-UUID set; the same instance must be threaded through the whole cascade of a single addToContext(UUID) call

    • getVisited

      Set<UUID> getVisited()
      Returns the shared, mutable set of UUIDs already visited during the current addToContext(UUID) cascade.
      Returns:
      the shared visited-UUID set, or null if not yet initialised
