Examples of gov.nasa.arc.mct.platform.spi.Platform

gov.nasa.arc.mct.platform.spi.Platform
The Platform interface represents the support required in the underlying MCT core. This class allows the platform implementation to be encapsulated and used within external facing API components. An instance of this class will be made available as an OSGi service during runtime. This interface supports the use of delegation instead of extension allowing the API and platform code to be decoupled. This interface is designed for use only for code within this package and thus is outside the scope of compatibility guarantees for other APIs. This class is not intended to be used by component authors
