Help regarding udf

[Former Member]

Hi Experts ,

I have a requirement in which I have to pad an incoming string with spaces based on it's length so that it's size ultimately become 10 character...can anyone give me a udf code for the same.I have tried myself but it didn't work

Hi Deepak,

Try this

1. calculate the length of the string(str) = len

2.

while (len <= 10)

{

a) append a space to the string

b) len = str.len

}

logically this is very simple ...but i do not know java ...

so was finding it difficult to code ...was getting some error after another

I want leading spaces not zeroes ...

Hi Deepak,

Try this

int len = str.length();

while (len <= 10)

{

str = str + " ";

len = str.length();

}

result.addValue(str);

Hi ,

Got the following when I tried this code

usr/sap/JXS/DVEBMGS00/j2ee/cluster/server0/./temp/classpath_resolver/Maped3f5b80b6e511dba9a0001125a6778d/source/com/sap/xi/tf/_MM_Inbound_Delv_.java:888: cannot resolve symbol symbol : variable result location: class com.sap.xi.tf._MM_Inbound_Delv_ result.addValue(str); ^

Hi Deepak,

Ok remove the result.addValue st and put

return str;

instead of it.

Try it now....

Deepak,

understand that the 'return' statement is when you choose the Radio button 'Cache'

as 'Value'

and it is 'result.addValue()' when you choose Radio button 'Cache' as 'Context'

Hi ,

This code is not executing ..and it is taking forever ...

int len = str.length();

while (len <= 10)

{

str = str + " ";

}

return str;

Hi Deepak,

for sure it is an infinite loop, you have to recompute the value of the variable len inside the loop or do in this way:

while (str.length() <= 10)
  str = str + " ";

result.addValue(str);
//return str; *** depending on the type of function

without the need to declare a variable for string lenght.

Hi Deepak,

You need to reassign the len variable in the while loop with the new length. You missed one stmt !!!!

Deepak,

try this:

while (len <= 10)

{

str = str + " ";

len++;

}

return str;

this will do

Thanks akhshay ..i hope under no circumstances the length

will exceed 10 ...I have fixed file length on the other end

<i>>>>i hope under no circumstances the length will exceed 10</i>

You can guard against this by putting in another statement at the beginning:

if (str.length() > 10)
    return str.substring(0,10);

... rest of your original code

Deepak,

Just create a UDF and click on <b>Value</b> radio button. In the arguments name the Argument as <b>str</b>.

Then inside you put as given by sergio:

while (str.length() <= 10)

str = str + " ";

return str;

--> Save and close.

Then it will work.

Deepak,

This function will resolve your issue:

For e.g. if a string has to be padded with leading zeros to make it 10 character long.

while (String.length()<Integer.parseInt(Length))

{

String = Value+String;

}

return String;
