Mapping problem in context handling

[Former Member]

Hi experts,

I am doing a file to file scenario in which i have to change the queue context is it possible? for simple context change we use ResultList.CC in advance UDF but what to do if we want to add a queue cahnge .To dig more deep into the problem i am explaining my scenario.

my output structure is <GROUP> .....(1 to unbounded)

<Records>....(1 to unbounded)

field1

field2

..

..

..

field13

In one group there can be many records and there will be multiple Groups.Suppose in my udf i want to add a queue change to add some field in other group then how will i achive it ? please guide me with ur inputs

The solution i got by appending as many space as the suprressed values

[GabrielSagaya]

function myudf(String a[], ResultList result, Container container)

{

for(int i=0;i<a.length;i++)

{

if(!a<i>.equals(""))

result.addValue(a<i>);

else

result.addContextChange();

}

}

[GabrielSagaya]

have addContextChange() in your UDF

function myudf(String a[], ResultList result, Container container)

{

for(int i=0;i<a.length;i++)

{

if(!a[<i>].equals(""))

result.addValue(a[<i>]);

else

result.addContextChange();

}

}

Hi,

context object is a generic term used to make a reference to message heder fileds in the XML file (also vth XPATH). Context of an element is nothing but just the level (with reference to its parent node) where the XML tag appears in the given XML document.

Hi Mario,

Thanks for ur quick reply,but when i used it i got the error" non-static method addContextChange() cannot be referenced from a static context ResultList.addContextChange();".please tell me if i have to do any other setting to use this code.Secondly hope u understand my requirement i have to add context change to move to diffrent queue not simple context change.

Please feel free to ask any question if u have not understood clearly .

Regards,

Saueabh

You can use result.addContextChange()

Hi Saurabh,

to force a context change in UDF, use:

ResultList.addContextChange();
