Method Detail

transformJavac

public static boolean transformJavac(InstructionContainer ic,
                                     StructuredBlock last)

Transforms the code

   DUP
   POP.getClass()
 

to a CheckNullOperator. This is what javac generates when it calls ".new" on an operand.

transformJikes

public static boolean transformJikes(IfThenElseBlock ifBlock,
                                     StructuredBlock last)

Transforms the code

   DUP
   if (POP == null) {
       throw null
   }
 

to a CheckNullOperator. This is what jikes generates when it calls ".new" on an operand.
