Session: Storing Entities

To store entities inside the session object, use one of the three store methods.

Syntax

First overload: Stores the entity in a session, then extracts the ID from the entity or generates a new one if it's not available.

void store(Object entity);

Second overload: Stores the entity in a session with given ID.

void store(Object entity, String id);

Third overload: Stores the entity in a session with given ID, forces concurrency check with given change vector.

void store(Object entity, String changeVector, String id);

Example

Employee employee = new Employee();
employee.setFirstName("John");
employee.setLastName("Doe");

// generate Id automatically
session.store(employee);

// send all pending operations to server, in this case only `Put` operation
session.saveChanges();
