package org.eclipse.osgi.service.resolver;


This class represents a native code specification.  A 
native code specification is different from other 
specification constraints which typically are resolved against
suppliers provided by other bundles.   A native code 
specification supplies it own suppliers which are matched
against the platform properties at resolve time and the 
supplier with the best match is selected.

 This interface is not intended to be implemented by clients. The StateObjectFactory should be used to construct instances. 


Since:3.4
