- org.springframework.jdbc.support.lob.TemporaryLobCreator

All Implemented Interfaces:
Closeable, AutoCloseable, LobCreator
```
public class TemporaryLobCreator
extends Object
implements LobCreator
```
LobCreator implementation based on temporary LOBs, using JDBC 4.0's Connection.createBlob() / Connection.createClob() mechanism.
Used by DefaultLobHandler's DefaultLobHandler.setCreateTemporaryLob(boolean) mode. Can also be used directly to reuse the tracking and freeing of temporary LOBs.
Since:
3.2.2
Author:
Juergen Hoeller

```
    Description copied from interface: LobCreator
    Set the given content as bytes on the given statement, using the given parameter index. Might simply invoke PreparedStatement.setBytes or create a Blob instance for it, depending on the database and driver.
    Specified by:
    setBlobAsBytes in interface LobCreator
    Parameters:
    ps - the PreparedStatement to the set the content on
    paramIndex - the parameter index to use
    content - the content as byte array, or null for SQL NULL
    Throws:
    SQLException - if thrown by JDBC methods

  - close
```
public void close()
```
    Description copied from interface: LobCreator
    Close this LobCreator session and free its temporarily created BLOBs and CLOBs. Will not need to do anything if using PreparedStatement's standard methods, but might be necessary to free database resources if using proprietary means.
    NOTE: Needs to be invoked after the involved PreparedStatements have been executed or the affected O/R mapping sessions have been flushed. Otherwise, the database resources for the temporary BLOBs might stay allocated.
