    • addObjectsAsSlot

      protected void addObjectsAsSlot(StructurePointer methodClass, HashMap<String,String> renameFields) throws CorruptDataException
      It walks through each field in this structure that is represented by methodClass and registers each field as a slot into ClassWalkerCallBack It uses the StructureDescriptor of J9DDR to get the FieldDescriptor of a structure. The name, type and address are found in the FieldDescriptor. The name, type and address are guaranteed to match the current core file, since they are taken from it.
      Parameters:
      methodClass - pointer class that is generated for the VM structure
      renameFields - list of names to rename the original field names in the structure
      Throws:
      CorruptDataException
