RAdapter 类 |
Platform adapter to bridge platform specific objects to HTML Renderer core library.
Core uses abstract renderer objects (RAdapter/RControl/REtc...) to access platform specific functionality, the concrete platforms implements those objects to provide concrete platform implementation. Those allowing the core library to be platform agnostic.
