question: protected void restoreFromContinuationData ( Map < String , Object > data ) { localProxyBuilder . set ( ( FactoryBuilderSupport ) data . get ( "proxyBuilder" ) ) ; contexts . set ( ( LinkedList < Map < String , Object > > ) data . get ( "contexts" ) ) ; }
target:  Restores the state of the current builder to the same state as an older build. Caution, this will destroy rather than merge the current build context if there is any,
