Record Class ActivitySpec

java.lang.Object
java.lang.Record
com.graphhopper.jsprit.core.problem.solution.spec.ActivitySpec
Record Components:
jobId - the ID of the job this activity belongs to
type - which activity of the job (VISIT for single-stop, PICKUP/DELIVERY for shipments)
options - optional overrides (null = use defaults)
public record ActivitySpec(String jobId, ActivityType type, ActivityOptions options) extends Record
Specifies one activity in a route.

This is pure data - no actual Activity objects are referenced. The spec is materialized into real activities when building the solution.
