CommonServiceLocator的这条评论中环境这个词的含义是什么

我想猜测"环境容器"与它是一个静态类有关，但这只是一个猜测。

或者这指的是标准模式？（即我真的需要阅读GoF书的封面）

namespace Microsoft.Practices.ServiceLocation
{
    /// <summary>
    /// This class provides the ambient container for this application. If your
    /// framework defines such an ambient container, use ServiceLocator.Current
    /// to get it.
    /// </summary>
    public static class ServiceLocator
    {
        private static ServiceLocatorProvider currentProvider;
        /// <summary>
        /// The current ambient container.
        /// </summary>
        public static IServiceLocator Current
        {
            get { return currentProvider(); }
        }
        /// <summary>
        /// Set the delegate that is used to retrieve the current container.
        /// </summary>
        /// <param name="newProvider">Delegate that, when called, will return
        /// the current ambient container.</param>
        public static void SetLocatorProvider(ServiceLocatorProvider newProvider)
        {
            currentProvider = newProvider;
        }
    }
}
