How to get CURRENT version label number through DFC code? - version-control

Question

public static IDfCollection getVersions() {
IDfQuery query = clientX.getQuery();// obtain an idfObject
query.setDQL(
"select r_object_id,object_name,r_version_label,owner_name from dm_document(all) where i_chronicle_id='090008868006d5be'");
IDfCollection collection = null;
try {
collection = query.execute(SessionFile.getSession(), IDfQuery.DF_READ_QUERY);
} catch (DfException e) {
e.printStackTrace();
}
return collection;
}
public class Versions {
public static void main(String[] args) {
IDfCollection collection = AllOperations.getVersions();
try {
int versionsCount = collection.getValueCount("r_object_id");
//IDfSysObject dfSysObject=(IDfSysObject) SessionFile.getSession().getObject(new DfId("09000886800a143e"));
while (collection.next()) {
//String versionNum = dfSysObject.getVersionLabels().getImplicitVersionLabel();
int i = 0;
while (i < versionsCount) {
System.out.println(collection.getRepeatingValue("r_version_label", i));
i++;
}
}
} catch (DfException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
Output of the above code is:
1.0,
1.1,
1.2,
CURRENT
in place of "CURRENT" label, I want to "get version number" like 2.0 or 3.0 etc which is latest document version number.
needed output like below :

Answer 1

First of all, this line:
int versionsCount = collection.getValueCount("r_object_id");
should rather be
int versionsCount = collection.getValueCount("r_version_label");
and has to be in the while(collection.next()) loop, this way it will properly iterate over all r_version_label values, so the code will now output:
1.0
1.1
1.2
CURRENT
2.0
you can now get rid of CURRENT (or in general get rid of all non values which can't be parsed to a float number).

Answer 2

IDfDocument doc = (IDfDocument) session.getObject(colDocuments.getId("r_object_id"));
String versionLabel = doc.getAllRepeatingStrings("r_version_label", null);
