Info steps tab

Info steps tab

As the GetRow() method returns the first row from any input stream (either input stream or info stream), the Info steps table is used when the rowMeta input and rowMeta information vary.

Read or get all the data values from the information stream before calling the getRow() method, as shown in the following code example:

if (first){
 first = false;
 
 /* TODO: Your code here. (Using info fields)
 
 FieldHelper infoField = get(Fields.Info, "info_field_name");
 
 RowSet infoStream = findInfoRowSet("info_stream_tag");
 
 Object[] infoRow = null;
 
 int infoRowCount = 0;
 
 // Read all rows from info step before calling getRow() method, which returns first row from any
 // input rowset. As rowMeta for info and input steps varies getRow() can lead to errors.
 while((infoRow = getRowFrom(infoStream)) != null){
 
   // do something with info data
   infoRowCount++;
 }
 */
}
 
Object[] r = getRow();
 
if (r == null) {
       setOutputDone();
       return false;
}
