本文整理了Java中org.eclipse.lsp4j.jsonrpc.Launcher类的一些代码示例，展示了Launcher类的具体用法。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。Launcher类的具体详情如下：
包路径：org.eclipse.lsp4j.jsonrpc.Launcher
类名称：Launcher

Launcher介绍

[英]This is the entry point for applications that use LSP4J. A Launcher does all the wiring that is necessary to connect your endpoint via an input stream and an output stream.
[中]这是使用LSP4J的应用程序的入口点。启动器完成通过输入流和输出流连接端点所需的所有连接。

代码示例

@Override

 LOG.debug("Created launcher for language server");
 launcher.startListening();
 LOG.debug("Started listening");
 LanguageServer remoteProxy = launcher.getRemoteProxy();
 LOG.debug("Got remote proxy");
 return remoteProxy;
}
