org.axonframework.messaging.eventhandling.processing.streaming.segmenting.SegmentMatcher

@Internal
public final class SegmentMatcher
extends Object

Utility class that matches a resolved sequence identifier against a Segment.

The sequence identifier is expected to be resolved through EventHandlingComponent.sequenceIdentifierFor(org.axonframework.messaging.eventhandling.EventMessage, org.axonframework.messaging.core.unitofwork.ProcessingContext) before matching, so any fallback for a SequencingPolicy that resolves no identifier is applied in a single place. This guarantees that scheduling and handling route an event to the same segment.
