Sorting a Notes Document Collection in Java

As I searched in net and could not find a sorted document collection in Java, basically it is available in lotus script. So I rewritten the same in Java.

I written a class by name sortCollection with methods on this like

GetEmptyDocumentCollection,

SortDocumentCollection ( the function takes a document collection as its argument and returns a sorted document collection in assending order).

class SortCollection {

Session session;

AgentContext agentContext;

Database currentDB;

SortCollection() throws NotesException

{

try {

session = NotesFactory.createSession();

agentContext = session.getAgentContext();

currentDB = agentContext.getCurrentDatabase();

} catch( NotesException e) {

throw e;

}

}

// gets an empty notes document collection

public DocumentCollection GetEmptyDocumentCollection() throws NotesException

{

DocumentCollection dc = currentDB.getProfileDocCollection("xxxxxxx");

try

{ if(dc.getCount() > 0 )

dc.removeAll(true);

return dc;

} catch( NotesException e) {

throw e;

}

}

// this method takes a unsorted notes document collection and returns a sorted collection.

public DocumentCollection SortDocumentCollection (DocumentCollection dc ) throws NotesException

{

System.out.println("SortDocumentCollection process Started");

try

{ int count;

count = dc.getCount();

if( count <= 1)

return dc;

Document docs[] = new Document[count];

Document loopDoc;

loopDoc = dc.getFirstDocument();

int i = 0;

while (loopDoc != null)

{

docs[i] = loopDoc;

loopDoc = dc.getNextDocument(loopDoc);

i= i+1;

}

Document outerLoopDoc;

Document innerLoopDoc;

DateTime outerLoopDocLastModDate;

DateTime innerLoopDocLastModDate;

for( int j=0; j <>

{

outerLoopDoc = docs[j];

for(int k=0; k <>

{

innerLoopDoc = docs[k];

innerLoopDocLastModDate = innerLoopDoc.getLastModified();

outerLoopDocLastModDate = outerLoopDoc.getLastAccessed();

if( innerLoopDocLastModDate.timeDifference(outerLoopDocLastModDate) > 0 )

{

Document tempDoc;

tempDoc = docs[j];

docs[j]= docs[k];

docs[k] = tempDoc ;

}

}

}

DocumentCollection returnDocColl;

returnDocColl = GetEmptyDocumentCollection();

for(int j=0; j

returnDocColl.addDocument(docs[j]);

System.out.println("SortDocumentCollection process Finished");

return returnDocColl;

} catch( NotesException e)

{ throw e;

}

}

}
