给这个函数加中文注释：static getCompilationHookscompilation if !compilation instanceof Compilation throw new TypeError The compilation argument must be an instance of Compilation ; let hooks = compi

/**

• 获取编译钩子函数
• @param {Compilation} compilation 编译对象
• @returns {Object} 钩子函数对象 */ static getCompilationHooks(compilation) { // 如果参数 compilation 不是 Compilation 的实例，则抛出类型错误 if (!(compilation instanceof Compilation)) { throw new TypeError( "The 'compilation' argument must be an instance of Compilation" ); } // 从 compilationHooksMap 中获取钩子函数对象 let hooks = compilationHooksMap.get(compilation); if (hooks === undefined) { // 如果没有获取到，则创建新的钩子函数对象 hooks = { linkPreload: new SyncWaterfallHook(["source", "chunk"]), linkPrefetch: new SyncWaterfallHook(["source", "chunk"]) }; // 将钩子函数对象存储到 compilationHooksMap 中 compilationHooksMap.set(compilation, hooks); } // 返回钩子函数对象 return hooks;
