    • getType

      public Type getType(int offset)
      Returns the type of the local variable that uses this local variable slot at the given bytecode offset. Care for legal bytecode offsets yourself, otherwise the return value might be wrong. May return 'null' if nothing is known about the type of this local variable slot at the given bytecode offset.
      Parameters:
      offset - bytecode offset.
      Returns:
      the type of the local variable that uses this local variable slot at the given bytecode offset.

    • getName

      public String getName(int offset)
      Returns the name of the local variable that uses this local variable slot at the given bytecode offset. Care for legal bytecode offsets yourself, otherwise the return value might be wrong. May return 'null' if nothing is known about the type of this local variable slot at the given bytecode offset.
      Parameters:
      offset - bytecode offset.
      Returns:
      the name of the local variable that uses this local variable slot at the given bytecode offset.

    • add

      public void add(String name, int startPc, int length, Type type) throws LocalVariableInfoInconsistentException
      Adds some information about this local variable (slot).
      Parameters:
      name - variable name
      startPc - Range in which the variable is valid.
      length - length of ...
      type - variable type
      Throws:
      LocalVariableInfoInconsistentException - if the new information conflicts with already gathered information.
