MergeAction (Neo4j Cypher DSL (Core) 2021.3.4 API)

java.lang.Object
- org.neo4j.cypherdsl.core.MergeAction

All Implemented Interfaces:

Visitable
```
@API(status=EXPERIMENTAL,
     since="2020.1.2")
public final class MergeAction
extends Object
implements Visitable
```
An action or event that happens after a MERGE clause. It can either be one of two types: MergeAction.Type.ON_CREATE or MergeAction.Type.ON_MATCH.
Both events supports the setting of properties, but not removing or adding labels. Multiple properties should be set in one action, but Cypher and openCypher allow for multiple merge actions, with the same or different types.

Since:

2020.1.2
