Class EquivalenceGraphUpdate

java.lang.Object

org.atlasapi.equivalence.EquivalenceGraphUpdate

public class EquivalenceGraphUpdate
extends Object

Represents the result of processing an equivalence assertion. One graph, containing the subject of the assertion will be updated, it will have either have had other graphs split out, other graphs merged in, or both.

Graphs split out are created. Graphs merged in are deleted.

If an assertion only changes internal edges in a graph, i.e. the actual membership of the graph is unchanged, then both created and updated are empty.

e.g. assuming a, b, c, d are separate to begin with:

1. a -> b, c : a is updated, b, c are deleted.
2. a -> c, d : a is updated, b is created, d is deleted.
3. a -> ∅ : a is updated, c, d are created.
