Context value

[Former Member]

Hi All,

How to read the second value of a context supressing the first one:

for eg:

<N1>1,2<N1>

<N2>3,4<N2>

output will be 2 and 4.Please give your inputs not able to do with graphical?

Hi Kumar,

Create a Value user defined function and name it as GetAfterComma. Take one argument as a.

Add this code:

Imports: java.*;

//write your code here

int k = a.length();

int i = a.indexOf(".");

i = i +1;

a = a.substring(i,k);

return(a);

Map like this:

Input field --> UDF --> target field.

So if input is 2,4 then you will have ouput as 4.

You can write simpe udf. Another way to achieve this.....

// pass input String as method argument and return type String

int index1 = input.indexOf(",");
String output = input.substring(index1+1, input.length());
return output;

use standard function copyvalue

You can use standard function copyvalue

You can use CopyValue() to copy the value of a position in the source structure and assign it to a target field

see this link for an perfect example

Hi KUMAR,

USE the below UDF with execution type All values of context

also make sure input to this UDF .........no contextchange between your four or two values.

public void calculate(String[] var1, ResultList result, Container container) throws StreamTransformationException{

if(var1.length>=4)
{
result.addValue(var1[1]);
result.addValue(var1[3]);
}
else
{
result.addValue(var1[1]);
}
}

Please let know if its helps you

Hi NKumar1,

If your values are numbers, you can use the graphical mapping as below:

N1

Constant (",") -> replaceString() -> ceil() -> {target field}

Constant (".")

Best Regards.
