Retrieving category value

[matasa]

Hi everybody,
I'm trying to retrieve category values from a livelink object and I'm affraid I don't get the correct result, so I'm asking you a bit of help.

I get the results from GetObjectAttributesEx, then I list each category field with AttrListNames.
At this point all look fine, I'm able to see the list of keys from the category. But when I try to retrieve the values matching the keys I do not get the correct data: this final step is done using AttrGetValues.

I've past the corresponding code below just in case. Thanks in advance for your help.

   // input as integer:  oid and vcategoryid
   int status;

    LLValue attrValuePath = (new LLValue()).setAssocNotSet();
    LLValue attrValues = (new LLValue()).setList();
    LLValue attrValues2= (new LLValue()).setList();  
    LLValue objID = (new LLValue()).setAssocNotSet();
    LLValue catVersion2 = (new LLValue()).setAssocNotSet(); 
    LLValue catID= (new LLValue()).setAssocNotSet();
    LLValue catVersion = new LLValue();
    LAPI_ATTRIBUTES attr= new LAPI_ATTRIBUTES(session);
  
    objID.add("ID", oid);

    catID.add("ID", vcategoryid ); 
    catID.add("Version", 0);
 
    if (doc.FetchCategoryVersion(catID, catVersion) != 0)
    { 
      // display error 
      return 0;
    }

    status = doc.GetObjectAttributesEx(objID,catID,catVersion2);
    // test status ... 
    status = attr.AttrListNames(catVersion,attrValuePath,attrValues2);
    // test status ...
   
   for(int k = 0; k < attrValues2.size(); k++) 
   {
     String currfield = attrValues2.toValue(k).toString();
     status = attr.AttrGetValues(catVersion, currfield, attr.ATTR_DATAVALUES, attrValuePath, attrValues);
     System.out.println(currfield + "=" +  attrValues.toValue(0).toString());
   }

I am not sure about this but the documentation says that the AttrListNames should be used only if there is a "set" category in your category definition.Is that the case here.

Also to look at the values use the function called PrintTypeTree which is actually a very good way to understand the datatsructure.I rarely use the for loop method.

Code was written by Glenn Heyin,Sprint

private static void printTypeTree(LLValue inVal, String szSep, String szName) {
			System.out.println(szSep + szName + " - " + printLLValueType(inVal.type()) + "\t" + printLLValue(inVal));
			if(inVal.type() == LLValue.LL_ASSOC ||
					inVal.type() == LLValue.LL_RECORD ||
					inVal.type() == LLValue.LL_TABLE) {
				LLNameEnumeration enumValue;
				enumValue = inVal.enumerateNames();
				while(enumValue.hasMoreElements()) {
					String elValue = enumValue.nextElement().toString();
					printTypeTree(inVal.toValue(elValue), "\t" + szSep, elValue);
				}
			}
			else {
				if(inVal.type() == LLValue.LL_LIST) {
					for(int i = 0; i < inVal.size(); i++) {
						printTypeTree(inVal.toValue(i), "\t" + szSep, "" + i);
					}
				}
			}
		}

		private static String printLLValue(LLValue llVal)
		{
			String returnString = "";

			switch (llVal.type()) {
			case LLValue.LL_BOOLEAN :
				returnString = "" + llVal.toBoolean();
				break;
			case LLValue.LL_DATE :
				returnString = llVal.toDate().toString();
				break;
			case LLValue.LL_DOUBLE :
				returnString = "" + llVal.toDouble();
				break;
			case LLValue.LL_INTEGER :
				returnString = "" + llVal.toInteger();
				break;
			case LLValue.LL_STRING :
				returnString = llVal.toString();
				break;
			default :
				break;
			}
			return returnString;
		}

		private static String printLLValueType(int iType) {
			String returnString = " ";
			switch (iType) {
			case LLValue.LL_ASSOC :
				returnString = "Type is ASSOC";
				break;
			case LLValue.LL_BOOLEAN :
				returnString = "Type is BOOLEAN";
				break;
			case LLValue.LL_DATE :
				returnString = "Type is DATE";
				break;
			case LLValue.LL_DOUBLE :
				returnString = "Type is DOUBLE";
				break;
			case LLValue.LL_ERROR :
				returnString = "Type is ERROR";
				break;
			case LLValue.LL_INTEGER :
				returnString = "Type is INTEGER";
				break;
			case LLValue.LL_LIST :
				returnString = "Type is LIST";
				break;
			case LLValue.LL_NOTSET :
				returnString = "Type is NOTSET";
				break;
			case LLValue.LL_RECORD :
				returnString = "Type is RECORD";
				break;
			case LLValue.LL_STRING :
				returnString = "Type is STRING";
				break;
			case LLValue.LL_TABLE :
				returnString = "Type is TABLE";
				break;
			case LLValue.LL_UNDEFINED :
				returnString = "Type is UNDEFINED";
				break;
			default :
				returnString = "Type is Unknown";
				break;
			}
			return returnString;
		}//helper method ends

Well, if I called the wrong number, why did you answer the phone?

Thanks Appu,
Actually, AttrListNames give the correct list of category "keys" and I can replace this loop by a specific existing key e.g I have a field "version" in my category, so I try the following but did not get the expected string back in attrValues.

status = attr.AttrGetValues(catVersion, "version", attr.ATTR_DATAVALUES, attrValuePath, attrValues);

I tried this very useful code, thanks for the tip and I can see the whole content of GetObjectAttributesEx resulting data, so I have to figure how to find my own data in there
