      • getBundleIdFromURL

        public java.lang.String getBundleIdFromURL​(java.net.URL url)
        Description copied from interface: IWeavingContext
        In an OSGi environment, determin which bundle a URL originated from. In a non-OSGi environment, implementors should return null.
        Specified by:
        getBundleIdFromURL in interface IWeavingContext
        Returns:
        null as we are not in an OSGi environment (therefore no bundles)

        getClassLoaderName in interface IWeavingContext
        Returns:
        classname@hashcode

        public boolean isLocallyDefined​(java.lang.String classname)
        Description copied from interface: IWeavingContext
        Return true if the classloader associated with this weaving context is the one that will define the class with the specified name. In a delegating classloader hierarchy this might check the parent won't define it and the child will - in OSGi it will do something else.
        Specified by:
        isLocallyDefined in interface IWeavingContext
        Parameters:
        classname - name of the class, eg. "java.lang.String"
        Returns:
        true if the associated classloader will define the class

        Specified by:
        getDefinitions in interface IWeavingContext
        Parameters:
        weaver -
        loader -
