Method Summary final public static  ObjectContainer openMemoryFile(MemoryFile memoryFile)      Operates just like ExtDb4o.openMemoryFile(ConfigurationMemoryFile) , but uses the global db4o Configuration Configuration context. opens an ObjectContainer for in-memory use . In-memory ObjectContainers are useful for maximum performance on small databases, for swapping objects or for storing db4o format data to other media or other databases. Be aware of the danger of running into OutOfMemory problems or complete loss of all data, in case of hardware or JVM failures. Parameters:   memoryFile - a MemoryFile MemoryFile to store the raw byte data. final public static  ObjectContainer openMemoryFile(Configuration config, MemoryFile memoryFile)      opens an ObjectContainer for in-memory use . In-memory ObjectContainers are useful for maximum performance on small databases, for swapping objects or for storing db4o format data to other media or other databases. Be aware of the danger of running into OutOfMemory problems or complete loss of all data, in case of hardware or JVM failures. Parameters:   config - a custom Configuration Configuration instance to be obtained via Db4o.newConfiguration Parameters:   memoryFile - a MemoryFile MemoryFile to store the raw byte data.
