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.

Mostvisitables
will render themselves into a Cypher fragment preceded with the actual classname. The representation however is not cached - in contrast to the ones for full statements. UsingtoString
is recommended for debugging purposes mainly, and not for production use.The concrete classname has been prepended to help debugging and actually to discourage using fragments to build queries without explicitly rendering them, either as statement or going through the renderer on purpose.
