Class BufferServiceImpl

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

All Implemented Interfaces:

java.io.Serializable, BufferService

public class BufferServiceImpl
extends java.lang.Object
implements BufferService, java.io.Serializable

Implement the BufferService for the DQP Embedded component. This implementation may use either an all-memory model (which is prone to OutOfMemoryErrors) or a mixed disk/memory model which requires use of a directory on the disk for file service access.
