  • Method Details

    • tableName

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

      Set<String> columns()
      Gets the column names stored for this entity.
      Returns:
      the column names.
    • getPrimaryKeyProperties

      SpannerPersistentProperty[] getPrimaryKeyProperties()
      Gets the primary key properties in order. Embedded object properties containing key parts are represented as a single property.
      Returns:
      an array of the properties comprising the primary key in order.
    • getFlattenedPrimaryKeyProperties

      List<SpannerPersistentProperty> getFlattenedPrimaryKeyProperties()
      Gets the primary key properties in order. Embedded object properties containing key parts are flattened into their multiple primary key properties.

      an array of the properties comprising the primary key in order.
    • getSpannerMappingContext

      SpannerMappingContext getSpannerMappingContext()
      Gets the SpannerMappingContext that can be used to create persistent entities of types that appear as properties of this entity.

      the SpannerMappingContext instance
    • getSpannerEntityProcessor

      SpannerEntityWriter getSpannerEntityProcessor()
      Gets a SpannerEntityProcessor that can be used to create Cloud Spanner keys from one or more persistent properties.
      Returns:
      a SpannerEntityProcessor.
    • getIdProperty

      Specified by:
      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.
      Parameters:
      handler - must not be null.
    • doWithColumnBackedProperties

      void doWithColumnBackedProperties(org.springframework.data.mapping.PropertyHandler<SpannerPersistentProperty> handler)

      Returns:
      true if the entity has a muti-field key
    • getPrimaryKeyColumnName

      String getPrimaryKeyColumnName()
      Returns a primary key column name; if there are multiple primary key columns, returns first one. In case of embedded keys it works recursively.
      Returns:
      a primary key column name
    • hasEagerlyLoadedProperties

      boolean hasEagerlyLoadedProperties()
      Returns true if the entity has at least one eagerly load interleaved property.
