public class FindEntitiesByPropertyValueExecutor extends PageableEntityRepositoryExecutorBase
FindEntitiesByPropertyValueExecutor is the executor for the findEntitiesByPropertyValue request. This request can be issued in parallel - the call to each request potentially running in a different thread.

  • Constructor Details

    • FindEntitiesByPropertyValueExecutor

      public FindEntitiesByPropertyValueExecutor(String userId, String entityTypeGUID, String searchCriteria, int fromEntityElement, List<InstanceStatus> limitResultsByStatus, List<String> limitResultsByClassification, Date asOfTime, String sequencingProperty, SequencingOrder sequencingOrder, int pageSize, String localMetadataCollectionId, AuditLog auditLog, OMRSRepositoryValidator repositoryValidator, String methodName)
      Create the executor. The parameters provide the parameters for issuing the requests and combining the results.
      Parameters:
      userId - unique identifier for requesting user.
      entityTypeGUID - GUID of the type of entity to search for. Null means all types will be searched (could be slow so not recommended).
      searchCriteria - String expression contained in any of the property values within the entities of the supplied type.
      fromEntityElement - the starting element number of the entities to return. This is used when retrieving elements beyond the first page of results. Zero means start from the first element.
      limitResultsByStatus - By default, entities in all statuses are returned. However, it is possible to specify a list of statuses (eg ACTIVE) to restrict the results to. Null means all status values.
      limitResultsByClassification - List of classifications that must be present on all returned entities.
      asOfTime - Requests a historical query of the entity. Null means return the present values.
      sequencingProperty - String name of the property that is to be used to sequence the results. Null means do not sequence on a property name (see SequencingOrder).
      sequencingOrder - Enum defining how the results should be ordered.
      pageSize - the maximum number of result entities that can be returned on this request. Zero means unrestricted return results size.
      localMetadataCollectionId - unique identifier for the local repository - may be null if no local repository
      auditLog - logging destination
      repositoryValidator - validator for resulting relationships
      methodName - calling method

  • Method Details

    • getClone

      public CloneableRepositoryExecutor getClone()
      Return a clone of this executor with the same command parameters and accumulator instance. This is used when setting up the parallel execution of the work. Each clone executes the calls to a single open metadata repository.
      Returns:
      clone of this executor

    • issueRequestToRepository

      public boolean issueRequestToRepository(String metadataCollectionId, OMRSMetadataCollection metadataCollection)
      Perform the required action for the supplied repository.
      Specified by:
      issueRequestToRepository in interface RepositoryExecutor
      Specified by:
      issueRequestToRepository in class RepositoryExecutorBase
      Parameters:
      metadataCollectionId - unique identifier for the metadata collection for the repository
      metadataCollection - metadata collection object for the repository
      Returns:
      boolean true means that the required results have been achieved
