  • Field Details

    • PROPERTY_SEPARATOR

      public static final String PROPERTY_SEPARATOR
      Some arbitrary characters that hopefully are not used in a @Property. We use them to separate the properties in composite primary keys when passing them through the existing API. This constant is not to be used outside OGM.

  • Method Details

    • joinPrimaryIndexAttributesIfNecessary

      public static String joinPrimaryIndexAttributesIfNecessary(String defaultPrimaryIndex, Object id)
      This method concatenates the keys of an id into one string in case the id is a map, aka a composite key.

      This method is the obverse of splitPrimaryIndexAttributes(String)

      Parameters:
      defaultPrimaryIndex - The default primary index to use (the one applicable when the id is not a composite key)
      id - The actual id
      Returns:
      The concatenated keys or the default, primary index to use (the name of the property annotated with @Id.

    • splitPrimaryIndexAttributes

      public static String splitPrimaryIndexAttributes(String property)
      This joins properties separated by PROPERTY_SEPARATOR into a literal map to be used to match on..
      Parameters:
      property - The property that may contain multiple, separated properties.
      Returns:
      A literal map or a single property reference

    • findOneByType

      public PagingAndSortingQuery findOneByType(String label, ID id, int depth)
      Description copied from interface: QueryStatements
      construct a query to fetch a single object with the specified id of a specific type
