Question

我使用Pentaho ddata集成的5.0.1版。使用UDJC，我以特定的方式操纵数据。当我预先确定UDJC步骤中的数据时，数据是正确的。但如果将输出复制到虚拟步骤，则数据与UDJC步骤中预先设定的数据不同。

由于 java代码如下：

import java.util.*;
long current_id=-1;
long tmp_id=-1;
long i=0;
Object[] out_row1 =null; 
public boolean processRow(StepMetaInterface smi, StepDataInterface sdi) throws KettleException
{
   // Read current Line
Object[] r = getRow();

if (r == null) {

    setOutputDone();
    return false;
}

String tmp = get(Fields.In, "date_mod").getString(r);
Long modif_id = get(Fields.In, "id").getInteger(r);
Long tmp_id = get(Fields.In, "items_id").getInteger(r);
Long id_search_option = get(Fields.In, "id_search_option").getInteger(r);
Long is_requester = get(Fields.In, "is_requester").getInteger(r);
String itemtype_link = get(Fields.In, "itemtype_link").getString(r);
String date_from = get(Fields.In, "date_from").getString(r);
String date_to = get(Fields.In, "date_to").getString(r);

if ( current_id==tmp_id )
{

    //No change
    if(null==tmp)  

        {
        Object[] out_row = createOutputRow(r, data.outputRowMeta.size());
        putRow(data.outputRowMeta, out_row);

        return true;
    }
        //A change Occure

    else 
    {

        //add modif            
        String tmp1 = get(Fields.In, "date_mod").getString(out_row1);
        Long modif_id1 = get(Fields.In, "id").getInteger(out_row1);
        String status=get(Fields.Out, "statusvalue").getString(out_row1);
        Long technicien=get(Fields.Out, "technicien").getInteger(out_row1);
        Long technical_group=get(Fields.Out, "technical_group").getInteger(out_row1);
        Long requester_group=get(Fields.Out, "requester_group").getInteger(out_row1);
        //New modif date
        if (modif_id1!=modif_id) 
        {                

            Object[] out_row= createOutputRow(r, data.outputRowMeta.size());
            get(Fields.Out, "date_from").setValue(out_row1,tmp);    
            out_row=out_row1;
            putRow(data.outputRowMeta, out_row);    
            date_to=get(Fields.Out, "date_from").getString(out_row1);
            get(Fields.Out, "date_to").setValue(out_row1,date_to);
            get(Fields.Out, "id").setValue(out_row1,modif_id);
        } 
        //The same modif date (Two CASE: same modif for multiple data set OR many modif 
        //for a data set
            if (id_search_option==12)//modif status
            {

                status = get(Fields.In, "old_value").getString(r);

Answer 1

如果我在输出行之前添加等待时间，则所有数据都是正确的。这可以解决我的问题但会降低我的表现。任何建议。

使用PDI输出UDJC
