  • Method Details

    • getId

      java.lang.String getId()
      Returns the id of this source which must be unique within the system, so there must only be exactly one data source with that id.
      Returns:
      the id of this data source

    • getName

      java.lang.String getName()
      Returns the name of this data source which might be used as a label, but never for referencing it.
      Returns:
      the name of this data source

    • getDescription

      java.lang.String getDescription()
      Returns the optional description for this data source.
      Returns:
      the description of this data source

    • findDataObjectByLookupIdAndDefinitionId

      DataObjectInstanceVariableContainer findDataObjectByLookupIdAndDefinitionId​(java.lang.String lookupId, java.lang.String definitionId)
      Lookup a single data object given by its lookup id and definition id.
      Parameters:
      lookupId - the lookup id of the data object to be returned
      definitionId - the data object definition id to load a data object for
      Returns:
      the data object instance, if found, null otherwise

    • findDataObjectByLookupIdAndDefinitionKey

      DataObjectInstanceVariableContainer findDataObjectByLookupIdAndDefinitionKey​(java.lang.String lookupId, java.lang.String definitionKey)
      Lookup a single data object given by its lookup id and definition key.
      Parameters:
      lookupId - the lookup id of the data object to be returned
      definitionKey - the data object definition key to load a data object for
      Returns:
      the data object instance, if found, null otherwise

    • createDataObjectInstanceBuilder

      DataObjectInstanceVariableContainerBuilder createDataObjectInstanceBuilder()
      Creates a new data object instance builder object used to create new data object instances and persist them.
      Returns:
      the data object instance builder object

    • createDataObjectModificationBuilder

      DataObjectModificationBuilder createDataObjectModificationBuilder​(java.lang.String definitionId)
      Creates a new data object modification builder used to modify an existing data object with strong type support. If needed by the data source implementation, the builder might load and hold the current data object first to allow modified data to be applied directly, specially, if partial updates are not supported as the modification builder might only update partial data of the object.
      Parameters:
      definitionId - the data object definition id to create a new modification builder for
      Returns:
      the data object modification builder

    • deleteDataObjectInstance

      void deleteDataObjectInstance​(java.lang.String lookupId, java.lang.String definitionId)
      Deletes the specified data object given by its lookup id and specified by the data object definition and model.
      Parameters:
      lookupId - the lookup id of the data object to be deleted
      definitionId - the data object definition id to delete an object instance for
