BatchingConstraintUpdateManager (OpenJPA Parent POM 4.0.0 API)

java.lang.Object
- org.apache.openjpa.jdbc.kernel.AbstractUpdateManager
- - org.apache.openjpa.jdbc.kernel.ConstraintUpdateManager
  - - org.apache.openjpa.jdbc.kernel.BatchingConstraintUpdateManager

All Implemented Interfaces:

UpdateManager, Configurable
```
public class BatchingConstraintUpdateManager
extends ConstraintUpdateManager
```
Batch update manager that writes the SQL in object-level operation order. This update manager initiates a BatchPreparedStatementManagerImpl which will utilize the JDBC addBatch() and executeBatch() APIs to batch the statements for performance improvement.

This is the default plug-in class for UpdateManager to support statement batching. You can plug-in your own statement batch implementation through the following property:
```
   < property name="openjpa.jdbc.UpdateManager"
     value="org.apache.openjpa.jdbc.kernel.YourOperationOrderUpdateManager" />
 
```
