Interface LoadType<T>

All Superinterfaces:

Iterable<T>, LoadIds<T>, Query<T>, QueryExecute<T>, com.google.appengine.api.datastore.QueryResultIterable<T>, SimpleQuery<T>

public interface LoadType<T>
extends LoadIds<T>, Query<T>

Once you have narrowed your interest to a type (via load().type(SomeType.class)), the command pattern can diverge into two directions: Either defining a parent or ids (which corresponds to a batch get) or calling query-related methods (which will produce a query).

Method Detail

parent

LoadIds<T> parent(Object keyOrEntity)

Define a parent for a get-by-key operation. After this, you must define an id() or ids().

All command objects are immutable; this method returns a new object instead of modifying the current command object.

Parameters:

keyOrEntity - - a Key, datastore Key, or entity pojo of the relevant entity to use as the key parent

Returns:

the next immutable step in the command chain, which allows you to define ids.
