  • Method Details

    • tableName

      String tableName()
      Gets the name of the Cloud Spanner table.
      Returns:
      the name of the table.

    • columns

      Set<String> columns()

      Returns:
      the column names.

    • getPrimaryKeyProperties

      SpannerPersistentProperty[] getPrimaryKeyProperties()

      getIdProperty in interface org.springframework.data.mapping.PersistentEntity<T,SpannerPersistentProperty>

    • doWithInterleavedProperties

      void doWithInterleavedProperties(org.springframework.data.mapping.PropertyHandler<SpannerPersistentProperty> handler)
      Applies the given PropertyHandler to all SpannerPersistentPropertys contained in this SpannerPersistentProperty that are collections of child entities.
