Interface EquivalenceRelation

All Known Implementing Classes:
SameLabel, SameShortId
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface EquivalenceRelation
Binary predicate that decides whether two ElementViews belong to the same equivalence class and should therefore be merged.

Implementations must be reflexive, symmetric, and transitive. CompositionOperator applies this relation to compute the partition automatically — callers do not need to drive the pairing loop themselves.

The parameter type is ElementView rather than SourcedElement so that the same relation can be applied both during Phase 1 composition (where inputs are SourcedElements) and during Phase 4 unification in Unifier (where inputs are ElementCreationCommands). Both types implement ElementView.
