Method Detail

load

public void load(com.google.cloud.datastore.FullEntity<?> node,
                 LoadContext ctx,
                 Path path,
                 Object into)

Description copied from interface: Populator

Loads the content of the specified datastore node into an existing POJO.

Specified by:

load in interface Populator<Object>

Parameters:

node - is the part of the native datastore entity tree we are transforming.

ctx - holds state information during an entity load.

path - is the current path to this POJO

save

public void save(Object pojo,
                 boolean index,
                 SaveContext ctx,
                 Path path,
                 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<Object>

Parameters:

pojo - 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

path - 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).
