This class is a hack to workaround the need to rewrite the entire
org.apache.lucene.store.db package after Sleepycat radically changed its
Java API from version 4.2.52 to version 4.3.21.
The code below extracts the package-accessible internal handle instances
that were the entrypoint objects in the pre-4.3 Java API and that wrap the
actual Berkeley DB C objects via SWIG. |
