本文整理了Java中org.rocksdb.RocksDB.loadLibrary方法的一些代码示例，展示了RocksDB.loadLibrary的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。RocksDB.loadLibrary方法的具体详情如下：
包路径：org.rocksdb.RocksDB
类名称：RocksDB
方法名：loadLibrary

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。
