    Description copied from interface: Populator
    
    Loads the content of the specified datastore node into an existing 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
  - save
```
public void save(P onPojo,
                 boolean index,
                 SaveContext ctx,
                 Path containerPath,
                 com.google.cloud.datastore.FullEntity.Builder<?> into)
```
    Description copied from interface: Populator
    
    Saves data from the POJO into the entity builder.
    
    Specified by:
    
    save in interface Populator<P>
    
    Parameters:
    
    onPojo - is an object from the pojo entity graph; possibly the whole graph or possibly just a leaf field.
    
    index - is whether the instruction so far is to index or not index property values
    
    containerPath - is the path that we have taken to get here, which could be long due to re-entrant translators (ie, an embedded pojo that also has a reference to the same class).
