      Determine whether or not given signature denotes a reference type.
      Parameters:
      signature - a signature
      Returns:
      true if signature denotes a reference type, false otherwise

    • getNumSlotsForType

      public static int getNumSlotsForType(String sig)
      Return how many stack frame slots a type whose signature is given will occupy. long and double values take 2 slots, while all other kinds of values take 1 slot.
      Parameters:
      sig - a type signature
      Returns:
      number of stack frame slots a value of the given type will occupy
