Expression result ( CodeChunk . Generator codeGenerator ) { Expression accessChain = buildAccessChain ( base , codeGenerator , chain . iterator ( ) ) ; if ( unpackFunction == null ) { return accessChain ; } else { return accessType . unpackResult ( accessChain , unpackFunction ) ; } }
Returns a code chunk representing the entire access chain . Null - safe accesses in the chain generate code to make sure the chain is non - null before performing the access .
