    com.google.cloud.datastore.Value<D>
    getValue(Object pojo, SaveContext ctx, Path containerPath)
    Get the value for the property and translate it into datastore format.
    void
    load(com.google.cloud.datastore.FullEntity<?> container, LoadContext ctx, Path containerPath, P intoPojo)
    Gets the appropriate value from the container and sets it on the appropriate field of the pojo.
    void
    save(P onPojo, boolean index, SaveContext ctx, Path containerPath, com.google.cloud.datastore.FullEntity.Builder<?> into)
    Gets the appropriate field value from the pojo and puts it in the container at the appropriate prop name and with the appropriate indexing.
    void
    setValue(Object pojo, com.google.cloud.datastore.Value<D> value, LoadContext ctx, Path containerPath)
    Set this raw datastore value on the relevant property of the pojo, doing whatever translations are necessary.
    String
    toString()
    This is easier to debug if we have a string value

      Gets the appropriate value from the container and sets it on the appropriate field of the pojo.
      Specified by:
      load in interface Populator<P>
      Parameters:
      container - is the part of the native datastore entity tree we are transforming.
      ctx - holds state information during an entity load.
      containerPath - is the current path to this POJO

      public void setValue(Object pojo, com.google.cloud.datastore.Value<D> value, LoadContext ctx, Path containerPath) throws SkipException
      Set this raw datastore value on the relevant property of the pojo, doing whatever translations are necessary.
      Throws:
      SkipException

    • save

      public void save(P onPojo, boolean index, SaveContext ctx, Path containerPath, com.google.cloud.datastore.FullEntity.Builder<?> into)
      Gets the appropriate field value from the pojo and puts it in the container at the appropriate prop name and with the appropriate indexing.
      Specified by:
      save in interface Populator<P>
      Parameters:
      onPojo - is the parent pojo which holds the property we represent
      index - is the default state of indexing up to this point
      containerPath - is the path to the container; each property will extend this path.

    • getValue

      public com.google.cloud.datastore.Value<D> getValue(Object pojo, SaveContext ctx, Path containerPath)
      Get the value for the property and translate it into datastore format.
