Class BufferManagerFactory

java.lang.Object
  com.metamatrix.common.buffer.BufferManagerFactory

public class BufferManagerFactory
extends java.lang.Object

Factory for BufferManager instances. One method will get a server buffer manager, as it should be instantiated in a running MetaMatrix server. That BufferManager is configured mostly by the passed in properties.

The other method returns a stand-alone, in-memory buffer manager. This is typically used for either in-memory testing or any time the query processor component is not expected to run out of memory, such as within the modeler.
