org.gcube.informationsystem.resourceregistry.client.ResourceRegistryClientImpl
All Implemented Interfaces:
org.gcube.informationsystem.resourceregistry.api.request.RequestInfo, ResourceRegistryClient
public class ResourceRegistryClientImpl extends org.gcube.informationsystem.resourceregistry.api.request.BaseRequestInfo implements ResourceRegistryClient
Default ResourceRegistryClient implementation. Talks to the Resource Registry service over HTTP via GXHTTPStringRequest, translating each interface method into the corresponding /access/... request, applying the client-side query parameter configuration (metadata policy, hierarchical mode, include-contexts, pagination) inherited from BaseRequestInfo, and unmarshalling the JSON response into model objects. A ContextCache and a TypesKnowledge base are used to avoid round-trips for context and type lookups; the *FromServer methods bypass both caches and always hit the server directly.

      • Supports pagination and metadata inclusion based on client configuration
      • Returns strongly-typed Context objects with role-appropriate detail level.
      Query Parameters limit (configurable via client configuration):

      • IS-Manager and Infrastructure-Manager see all contexts in the system
      • Context-Manager sees contexts within their management scope
      • Other users see contexts they have explicit access to.
      Authorization Requirements:
      • All users must have a valid token and basic read permissions to list contexts they have access to.
      Example Usage: 
       ResourceRegistryClient client = ResourceRegistryClientFactory.create();

      It reads the context from server by UUID string. The cache used for contexts is bypassed and not updated. Corresponding REST API: GET /access/contexts/{context-uuid}[?includeMeta={true|false}] Operation Behavior:
      • Retrieves the context with the specified UUID from the system
      • Returns the complete context object with all accessible properties
      • Direct UUID-based context retrieval without additional processing.
      Query Parameters includeMeta (configurable via client configuration):
      • Whether to include metadata in the response instance
      • Default value: false (basic information only)
      • Usage: client.setIncludeMeta(true)
      • Values: true (includes metadata with role-based filtering) | false (basic information only)
      • Query parameter: InstancePath.METADATA_POLICY_QUERY_PARAMETER
      • Restriction: IS-Manager, Infrastructure-Manager, and Context-Manager see complete metadata including sensitive information (createdBy, lastUpdatedBy); other users see filtered metadata with sensitive fields obfuscated.
      Input Processing:
      • Accepts a properly formatted UUID object
      • No additional processing or conversion required
      • Direct UUID-based context retrieval.
      Context Access:
      • The context must be accessible to the current user based on authorization level
      • IS-Manager and Infrastructure-Manager can retrieve any context without restrictions
      • Context-Manager can retrieve contexts within their management scope
      • Other users can retrieve contexts they have explicit access to.
      Authorization Requirements:
      • All users must have a valid token and read permissions for the specific context to retrieve it.
      Example Usage: 
       ResourceRegistryClient client = ResourceRegistryClientFactory.create();
 
 UUID contextUuid = UUID.fromString("c0f314e7-2807-4241-a792-2a6c79ed4fd0");
 
 // Basic usage - read context
 Context context = client.getContext(contextUuid);
 System.out.println("Context name: " + context.getName());
 
 // With metadata for non-admin users
 client.setIncludeMeta(true);
 Context contextWithMeta = client.getContext(contextUuid);
      Parameters:
      uuid - the UUID string of the context to retrieve
      Returns:
      the Context read from server
      Throws:
      org.gcube.informationsystem.resourceregistry.api.exceptions.contexts.ContextNotFoundException - if the context is not found

      Retrieves the type DAG node for a specific type identified by its model element class. The DAG node contains the type definition and its hierarchical position within the type system.

      Invocation-specific options and immutable response metadata are available through RequestInfo.serverResponses().

      Specified by:

    • queryTypes

      public String queryTypes(String jsonQuery) throws org.gcube.informationsystem.resourceregistry.api.exceptions.queries.InvalidQueryException, org.gcube.informationsystem.resourceregistry.api.exceptions.ResourceRegistryException
      Executes a read-only JSON Query-By-Example payload against the global Types collection. The payload must be a non-null JSON object targeting ResourceSchema, FacetSchema, IsRelatedToSchema, ConsistsOfSchema, or PropertySchema. Every authenticated role may invoke the operation and no Context-scoped token is required.

      ResourceRegistryRequestOptions may override limit (default 10, maximum 50), offset (default 0), depth (default -1), and metadataPolicy (default none) for one invocation. Plain name, source, and target filters use depth. An _emit payload returns flat, native-typed aliases and supersedes metadata inclusion. Per-request options take precedence over this client's pagination and metadata defaults.

      The method has no local cache or mutation side effects. It returns [] when no definition matches. Pagination links and parameter/projection warnings are available through RequestInfo.serverResponses().

      Specified by:
      queryTypes in interface ResourceRegistryClient
      Parameters:
      jsonQuery - non-null JSON object describing the Type definitions to search for
      Returns:
      JSON array string containing full Type definitions or flat projection rows; never null
      Throws:
      org.gcube.informationsystem.resourceregistry.api.exceptions.queries.InvalidQueryException - if the payload is malformed, structurally invalid, or targets an unsupported Type category
      org.gcube.informationsystem.resourceregistry.api.exceptions.ResourceRegistryException - if request construction, transport, response processing, or server-side persistence fails
