org.hibernate.ogm.datastore.neo4j.dialect.impl.Neo4jSequenceGenerator
Generates the next value of an id sequence as represented by {@link IdSourceKey}.
Both, {@link IdSourceType#TABLE} and {@link IdSourceType#SEQUENCE} are supported. For the table strategy, nodes inthe following form are used (the exact property names and the label value can be configured using the options exposed by {@link OgmTableGenerator}):
```
 (:hibernate_sequences:TABLE_BASED_SEQUENCE { sequence_name = 'ExampleSequence', current_value : 3 }) 
```
For the sequence strategy, nodes in the following form are used (the sequence name can be configured using the option exposed by {@link OgmSequenceGenerator}):
```
 (:SEQUENCE { sequence_name = 'ExampleSequence', next_val : 3 }) 
```
Sequences are created at startup.
A write lock is acquired on the node every time the sequence needs to be updated. @author Davide D'Alto <davide@hibernate.org> @author Gunnar Morling
