Hi,

There is no build in service for sorting…you have to write a java service for it…or you can build on the logic in flow too

Here is a sample how you can do it…

input:
itemList(document List)
keyField(String)
sortDecending(String)

output:
itemList(document List)
sorted(String)

IData[] sortedItemList = null; 
 
// pipeline 
IDataCursor pipelineCursor = pipeline.getCursor(); 
IData[] itemList = IDataUtil.getIDataArray( pipelineCursor, "itemList" ); 
String keyField = IDataUtil.getString( pipelineCursor, "keyField" ); 
boolean sortDescending =  
   (Boolean.valueOf(IDataUtil.getString( pipelineCursor,  
   "sortDescending" ))).booleanValue(); 
pipelineCursor.destroy(); 
 
if(itemList != null) 
{ 
    sortedItemList =  
       IDataUtil.sortIDataArrayByKey(itemList,  
       keyField,  
       IDataUtil.COMPARE_TYPE_COLLATION,  
       null,  
       sortDescending); 
} 
 
// pipeline 
pipelineCursor = pipeline.getCursor(); 
IDataUtil.put( pipelineCursor,  
   "sorted", sortedItemList==null ? "false" : "true"); 
pipelineCursor.destroy();
