Class MergeAction

java.lang.Object
org.neo4j.cypherdsl.core.MergeAction
All Implemented Interfaces:
Visitable
@API(status=STABLE, 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.
