Example 11 with EventContext

use of io.spine.core.EventContext in project core-java by SpineEventEngine.

the class EventFactory method createEvent.

/**
 * Creates an event for the passed event message.
 *
 * <p>The message passed is validated according to the constraints set in its Protobuf
 * definition. In case the message isn't valid, an {@linkplain ValidationException
 * exception} is thrown.
 *
 * <p>In the message is an instance of {@code Any}, it is unpacked for validation.
 *
 * <p>It is recommended to use a corresponding {@linkplain io.spine.validate.ValidatingBuilder
 * ValidatingBuilder} implementation to create a message.
 *
 * @param messageOrAny the message of the event or the message packed into {@code Any}
 * @param version      the version of the entity which produces the event
 * @throws ValidationException if the passed message does not satisfy the constraints
 *                             set for it in its Protobuf definition
