BufferServiceImpl (Runtime Engine 10.3.1 API)

java.lang.Object
- org.teiid.services.BufferServiceImpl

All Implemented Interfaces:

Serializable, org.teiid.dqp.service.BufferService
```
public class BufferServiceImpl
extends Object
implements org.teiid.dqp.service.BufferService, Serializable
```
Implements the BufferService. This implementation may use either an all-memory model (which is typically only for testing) or a mixed disk/memory model which requires use of a directory on the disk for file service access.
