EmbedSavepoint (Apache Derby V10.14 Internals)

java.lang.Object
- org.apache.derby.impl.jdbc.ConnectionChild
- - org.apache.derby.impl.jdbc.EmbedSavepoint

All Implemented Interfaces:

java.sql.Savepoint
```
final class EmbedSavepoint
extends ConnectionChild
implements java.sql.Savepoint
```
This class implements the Savepoint interface from JDBC 3.0. This allows to set, release, or rollback a transaction to designated Savepoints. Savepoints provide finer-grained control of transactions by marking intermediate points within a transaction. Once a savepoint has been set, the transaction can be rolled back to that savepoint without affecting preceding work.
Supports
- JSR169 - no subsetting for java.sql.Savepoint
- JDBC 3.0 - class introduced in JDBC 3.0
