RocksDB.loadLibrary介绍

[英]Loads the necessary library files. Calling this method twice will have no effect. By default the method extracts the shared library for loading at java.io.tmpdir, however, you can override this temporary location by setting the environment variable ROCKSDB_SHAREDLIB_DIR.
[中]加载必要的库文件。调用此方法两次将无效。默认情况下，该方法提取共享库以在java上加载。伊奥。然而，tmpdir可以通过设置环境变量ROCKSDB_SHAREDLIB_DIR来覆盖这个临时位置。
