Class TypeDefCache

java.lang.Object
org.odpi.openmetadata.adapters.repositoryservices.xtdb.repositoryconnector.cache.TypeDefCache
public class TypeDefCache extends Object
A shadow cache of all typeDef information. This is necessary to maintain due to fact that caching in the OMRSRepositoryContentManager does not occur until AFTER the OMRSMetadataCollection operation (i.e. addTypeDef) is fully completed: making it impossible to use the repositoryHelper inside any method that addTypeDef itself may call.

      public static AttributeTypeDef getAttributeTypeDef(String typeDefGUID)
      Retrieve the attribute type definition for the given GUID.
      Parameters:
      typeDefGUID - unique identifier of the attribute type definition

      AttributeTypeDef that matches the GUID, or null if there is no such attribute type definition

    • removeAttributeTypeDef

      public static void removeAttributeTypeDef(String typeDefGUID)
      Remove the cached attribute type definition.
      Parameters:
      typeDefGUID - unique identifier of the attribute type definition to remove from the cache

    • getAllSuperTypes

      public static List<TypeDefLink> getAllSuperTypes(String typeDefGUID)
      Retrieve a list of all supertypes of the provided type definition.
      Parameters:

      public static Map<String,PropertyKeywords> getAllPropertyKeywordsForTypeDef(String typeDefGUID)
      Retrieve a map of all property keywords for the provided type definition.
      Parameters:
      typeDefGUID - unique identifier of the type definition for which to retrieve all properties
      Returns:
      Map<String, PropertyKeywords> keyed by unqualified (simple) property name with the qualified property keywords as the value

    • getPropertyKeywords

      public static PropertyKeywords getPropertyKeywords(String typeDefGUID, String propertyName)
      Retrieve the property keywords for the provided property in the specified type definition.

      Parameters:
      actualTypeName - name of the entity type
      expectedTypeName - name of the expected type
      Returns:
      boolean if they match (a null in actualTypeName results in false; a null in expectedType results in true)
