[External] : RE: adding an interface to a class

[Chen Liang]

Might be that you have a class that's not java.lang.String but also has this simple name of String. Note that bere is not a technical support channel, and if you are reporting an issue, you should provide steps of reproduction or problem/code analysis.

Subject: [External] : RE: adding an interface to a class


I must be missing something.  This works:

      ClassDesc cd = ClassDesc.of(name); // (name is string containing binary name)

      ClassEntry ce = poolBuilder.classEntry(cd);



But this gets a compile error:

      Utf8Entry ue = poolBuilder.uft8Entry(name); // (name is string containing internal form)



daikon/dcomp/ClassGen24.java:103: error: cannot find symbol

    Utf8Entry ue = poolBuilder.uft8Entry(name);

                                                   ^

  symbol:   method uft8Entry(String)

  location: variable poolBuilder of type ConstantPoolBuilder



      ClassEntry ce = poolBuilder.classEntry(ue);



Thank you,

Mark

Correct.  (For bonus points, you should also check to make sure it is not already in the list of implemented interfaces.)

I might be missing something, but I see only a method to set all the interfaces of a class.  So to add an interface I have to get the current list of interfaces, add mine to it and then reset the entire list.  Is that correct?



Thank you,
