------------------------------------
Summary: Use explicit ArcId in GraphChangeHandler methods
Key: CAY-2555
URL: https://issues.apache.org/jira/browse/CAY-2555
Project: Cayenne
Issue Type: Improvement
Components: Core Library
Reporter: Nikita Timofeev
Assignee: Nikita Timofeev
Fix For: 4.2.M1
{{GraphChangeHandler}} uses plain {{Object}} as arc identifier:
{code:java}
..
void arcCreated(Object nodeId, Object targetNodeId, Object arcId);
void arcDeleted(Object nodeId, Object targetNodeId, Object arcId);
..
{code}
We can introduce {{ArcId}} object instead that can hold forward and reverse arc
names:
{code:java}
public class ArcId {
private final String forwardArc;
private final String reverseArc;
// ...
}
{code}
This change should simplify code maintenance and refactoring.
