 org.jacorb.orb.BufferManager
| BufferManager | | final public class BufferManager (Code) | | 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.

| configure | | public static synchronized void configure(Configuration configuration)(Code) | | configures the BufferManager, in turn configures the singleton.
Must be called before getInstance() !

| getBuffer | | public byte[] getBuffer(int initial)(Code) | | |
| getBuffer | | public synchronized byte[] getBuffer(int initial, boolean cdrStr)(Code) | | getBuffer returns a new buffer.
Parameters:
initial - an int value
Parameters:
cdrStr - a boolean value to denote if CDROuputStream is caller(may use cache in this situation) a byte[] value |
| getPreferredMemoryBuffer | | public byte[] getPreferredMemoryBuffer()(Code) | | |
| release | | public synchronized void release()(Code) | | |
| returnBuffer | | public void returnBuffer(byte[] current)(Code) | | |
| returnBuffer | | public synchronized void returnBuffer(byte[] current, boolean cdrStr)(Code) | | Describe returnBuffer method here.
Parameters:
current - a byte[] value
Parameters:
cdrStr - a boolean value value to denote if CDROuputStream iscaller (may use cache in this situation) |
