mozilla::services namespace 编辑

The services C++ namespace offers an easy and efficient alternative for obtaining a service as compared to the indirect XPCOM approach: GetService(), CallGetService(), etc methods are expensive and should be avoided when possible.

To use it, you first need to include the header into your C++ file:

#include "mozilla/Services.h"

Then you can obtain references to services by simply accessing them from the mozilla::services namespace. For example, to obtain a reference to the IOService:

nsCOMPtr<nsIIOService> ioService = mozilla::services::GetIOService();

Provided service getters

More services will be added as needed.
