CachedMetadataProvider

  • Namespace: PPDS.Dataverse.Metadata
  • Assembly: PPDS.Dataverse
  • Kind: Class
  • Implements: ICachedMetadataProvider, IDisposable

Summary​

Provides cached access to Dataverse metadata, wrapping PPDS.Dataverse.Metadata.IMetadataQueryService with per-session caching to minimize round-trips.

Members​

Constructors​

CachedMetadataProvider(IMetadataQueryService metadataService)​

CachedMetadataProvider(IMetadataQueryService metadataService)

Creates a new PPDS.Dataverse.Metadata.CachedMetadataProvider.

  • Param metadataService: The underlying metadata service.

Methods​

Dispose​

void Dispose()

(inherited from System.IDisposable.Dispose)

GetAttributesAsync​

Task<IReadOnlyList<AttributeMetadataDto>> GetAttributesAsync(string entityLogicalName, CancellationToken ct)

Gets attributes for an entity. Lazy-loaded on first access and cached with a 5-minute TTL.

  • Param entityLogicalName: The entity logical name.

  • Param ct: Cancellation token.

  • Returns: List of attribute metadata.

GetEntitiesAsync​

Task<IReadOnlyList<EntitySummary>> GetEntitiesAsync(CancellationToken ct)

Gets all entities from cache. The entity list is populated by PPDS.Dataverse.Metadata.ICachedMetadataProvider.PreloadAsync(System.Threading.CancellationToken) and cached indefinitely for the session lifetime.

  • Param ct: Cancellation token.

  • Returns: List of entity summaries.

GetRelationshipsAsync​

Task<EntityRelationshipsDto> GetRelationshipsAsync(string entityLogicalName, CancellationToken ct)

Gets relationships for an entity. Lazy-loaded on first access and cached with a 5-minute TTL.

  • Param entityLogicalName: The entity logical name.

  • Param ct: Cancellation token.

  • Returns: Entity relationships grouped by type.

InvalidateAll​

void InvalidateAll()

Invalidates all cached metadata. The next access will re-fetch from Dataverse.

InvalidateEntity​

void InvalidateEntity(string entityLogicalName)

Invalidates cached metadata for a specific entity (attributes and relationships). The entity list cache is not affected.

  • Param entityLogicalName: The entity logical name to invalidate.

InvalidateEntityList​

void InvalidateEntityList()

Invalidates the cached entity list. The next call to PPDS.Dataverse.Metadata.ICachedMetadataProvider.GetEntitiesAsync(System.Threading.CancellationToken) will re-fetch from Dataverse. Use after table create/delete operations.

InvalidateGlobalOptionSets​

void InvalidateGlobalOptionSets()

Invalidates any cached global option set data. Currently a no-op since global option sets are not cached, but provides a stable API for cache invalidation after global choice create/update/delete operations.

PreloadAsync​

Task PreloadAsync(CancellationToken ct)

Eagerly loads the entity list into cache. Call this early (e.g., on environment connect) so that entity names are available for IntelliSense without delay.

  • Param ct: Cancellation token.
