Examples of BufferManager

com.mysql.clusterj.tie.DbImpl.BufferManager
org.apache.fop.system.BufferManager
org.eclipse.jdt.internal.core.BufferManager
The buffer manager manages the set of open buffers. It implements an LRU cache of buffers.
org.jacorb.orb.BufferManager
A BufferManager is used to share a pool of buffers and to implement a buffer allocation policy. This reduces the number of memory allocations and deallocations and the overall memory footprint. Buffers are generally created on demand. The BufferManager uses a singleton pattern, so will only be a single shared BuffferManager across all ORBs in a process. @author Gerald Brose, FU Berlin @version $Id: BufferManager.java,v 1.29 2009-04-25 10:10:35 andre.spiegel Exp $
org.jboss.forge.shell.integration.BufferManager
A BufferManager is responsible for managing a shell buffer in Forge. @author Mike Brock
org.modeshape.jcr.query.BufferManager
A manager of temporary buffers used in the query system. @author Randall Hauch (rhauch@redhat.com)
org.teiid.common.buffer.BufferManager
The buffer manager controls how memory is used and how data flows through the system. It uses {@link StorageManager storage managers}to retrieve data, store data, and transfer data. The buffer manager has algorithms that tell it when and how to store data. The buffer manager should also be aware of memory management issues.
