Examples of 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 $

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.

      Arrays.asList(1),
      Arrays.asList(2),
      Arrays.asList(3)
    }, 2));
    BufferManager bm = BufferManagerFactory.getStandaloneBufferManager();
    TupleBuffer tb = bm.createTupleBuffer(Arrays.asList(new ElementSymbol("x")), "test", TupleSourceType.PROCESSOR);
    bi.setBuffer(tb, true);  //$NON-NLS-1$
    bi.nextTuple();
    bi.mark();
    bi.nextTuple();
    bi.reset();
