Examples of com.google.code.gaeom.ObjectStoreSession.load()

com.google.code.gaeom.ObjectStoreSession.load()
Begins a {@link LoadById} command to load instances of {@code type}. The load command must be terminated by a call to now() or later() to specify synchronous or asynchronous operation. You will need to specify the id values (not keys) to the command before terminating. @param type the class of the instances you want to load @return the {@link LoadById} command instance
