Class ResourceRegistryQueryTemplateClientImpl

java.lang.Object
org.gcube.informationsystem.resourceregistry.api.request.BaseRequestInfo
org.gcube.informationsystem.resourceregistry.queries.templates.ResourceRegistryQueryTemplateClientImpl
All Implemented Interfaces:
org.gcube.informationsystem.resourceregistry.api.request.RequestInfo, ResourceRegistryQueryTemplateClient
public class ResourceRegistryQueryTemplateClientImpl extends org.gcube.informationsystem.resourceregistry.api.request.BaseRequestInfo implements ResourceRegistryQueryTemplateClient
Default implementation of ResourceRegistryQueryTemplateClient, backed by HTTP calls to the Resource Registry service. Unlike the sibling Context/Schema clients, this implementation keeps no local cache: every operation is a direct round-trip to the server.

      Throws:
      org.gcube.informationsystem.resourceregistry.api.exceptions.queries.templates.QueryTemplateNotFoundException - If no query template is found with the specified name
      org.gcube.informationsystem.resourceregistry.api.exceptions.ResourceRegistryException - If an error occurs during template deletion

    • delete

      public boolean delete(String queryTemplateName) throws org.gcube.informationsystem.resourceregistry.api.exceptions.queries.templates.QueryTemplateNotFoundException, org.gcube.informationsystem.resourceregistry.api.exceptions.ResourceRegistryException
      Deletes an existing query template from the Resource Registry by its name.

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

      Specified by:
      delete in interface ResourceRegistryQueryTemplateClient
      Parameters:
      queryTemplateName - The name of the query template to delete; must not be null or blank
      Returns:
      true if the query template was successfully deleted
      Throws:
      org.gcube.informationsystem.resourceregistry.api.exceptions.queries.templates.QueryTemplateNotFoundException - If no query template is found with the specified name
      org.gcube.informationsystem.resourceregistry.api.exceptions.ResourceRegistryException - If an error occurs during template deletion

    • jsonQuery

      public String jsonQuery(String query) throws org.gcube.informationsystem.resourceregistry.api.exceptions.queries.InvalidQueryException, org.gcube.informationsystem.resourceregistry.api.exceptions.ResourceRegistryException
      Executes a JSON Query against the Query Template collection itself (e.g. by name), as opposed to ResourceRegistryQueryTemplateClient.run(String), which executes a named template's own stored query.

      Invocation-specific options and immutable response metadata are available through RequestInfo.serverResponses(). Request options configured via ResourceRegistryRequestOptions may specify pagination (limit, offset) and metadataPolicy.

      Specified by:
      jsonQuery in interface ResourceRegistryQueryTemplateClient
      Parameters:
      query - JSON object describing the Query Template structure to search for; must not be null or blank
      Returns:
      JSON array string of matching query template definitions, or empty array string "[]" if none match
      Throws:
      org.gcube.informationsystem.resourceregistry.api.exceptions.queries.InvalidQueryException - if the query syntax is invalid
      org.gcube.informationsystem.resourceregistry.api.exceptions.ResourceRegistryException - if the lookup fails

    • jsonQuery

      public List<org.gcube.informationsystem.queries.templates.reference.entities.QueryTemplate> jsonQuery(org.gcube.com.fasterxml.jackson.databind.JsonNode jsonNode) throws org.gcube.informationsystem.resourceregistry.api.exceptions.queries.InvalidQueryException, org.gcube.informationsystem.resourceregistry.api.exceptions.ResourceRegistryException
      Executes a JSON Query against the Query Template collection itself and deserializes the matching definitions. See ResourceRegistryQueryTemplateClient.jsonQuery(String) for the underlying contract.

      Invocation-specific options and immutable response metadata are available through RequestInfo.serverResponses(). Request options configured via ResourceRegistryRequestOptions may specify pagination (limit, offset) and metadataPolicy.

      This method is a type-safe wrapper that delegates to jsonQuery(String) for implementation details.
      Specified by:
      jsonQuery in interface ResourceRegistryQueryTemplateClient
      Parameters:
      jsonNode - JsonNode describing the Query Template structure to search for; must not be null
      Returns:
      the matching query template definitions, or an empty list if none match
      Throws:
      org.gcube.informationsystem.resourceregistry.api.exceptions.queries.InvalidQueryException - if the query syntax is invalid
      org.gcube.informationsystem.resourceregistry.api.exceptions.ResourceRegistryException - if the lookup fails

    • query

      public List<org.gcube.informationsystem.queries.templates.reference.entities.QueryTemplate> query(String query) throws org.gcube.informationsystem.resourceregistry.api.exceptions.queries.InvalidQueryException, org.gcube.informationsystem.resourceregistry.api.exceptions.ResourceRegistryException
      Executes a JSON Query against the Query Template collection itself and returns the matching definitions.

      Convenience alias delegating to ResourceRegistryQueryTemplateClient.jsonQuery(String) followed by deserialization to a list of QueryTemplate entities.

      Invocation-specific options and immutable response metadata are available through RequestInfo.serverResponses(). Request options configured via ResourceRegistryRequestOptions may specify pagination (limit, offset) and metadataPolicy.

      Specified by:
      query in interface ResourceRegistryQueryTemplateClient
      Parameters:
      query - JSON Query-By-Example string describing the Query Template structure to search for; must not be null or blank
      Returns:
      a list of matching query templates, or an empty list if no query templates match
      Throws:
      org.gcube.informationsystem.resourceregistry.api.exceptions.queries.InvalidQueryException - if the query syntax is invalid
      org.gcube.informationsystem.resourceregistry.api.exceptions.ResourceRegistryException - if the lookup fails or an error occurs during retrieval
