java.lang.Objectorg.jacorb.orb.BufferManager
public final class 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.
