Entity Name

Name of the JavaScript transformation. Maximum length is 32 characters.

Description

Description of the JavaScript transformation. Maximum length is 256 characters.

JavaScript Functions

JavaScript transformation program to transform records and insert delimiters. The program must include the filter function that applies the transformations. Maximum length is 4000 characters.

Read operations from the input and write operations to the output without an intermediate byte array-to-string conversion. Use simple read and write operations if you want to only append or prepend strings to the input.
Read the byte array from the input as a string and write the string to the output as a byte array. Use read and write operations that convert from and to a byte array form if you want to transform the data.
Transform the record.

function transform(input, output, utility){
     //TODO:Add your function code here
    }

input

Input data stream in byte array form.

output

ByteArrayOutputStream

object to which you write transformed data as a byte array.

utility

Built-in utility class that includes methods for the read and write operations that you require to transform data and methods to append LF and CRLF delimiters.

The

utility

class includes the following Java methods:

getBytes(String str)
. Convert a text string to a byte array.
getString(byte[] bytes)
. Convert a byte array to a text string.
getBytesForLF()
. Get the raw byte sequence of the line feed delimiter.
getBytesForCRLF()
. Get the raw byte sequence of the carriage return line feed delimiter.

You can also use your own methods instead of the methods in the

utility

class. For example, you can add a method if you want to add delimiters other than the line feed and carriage return line feed delimiters. Define your own methods in the

transform

function, and then call the methods from the

transform

function, as shown in the following example:

function transform(input, output, utility)
{
//funtion body
// Call to custom function MyFunction1
   myFunction1();
// Call to custom function MyFunction2
   myFunction2();

   // Definition of custom function myFunction1
   function myFunction1(a,b){
   // myFunction1 body
   }
   // Definition of custom function myFunction2
function myFunction2(c,d){
   // myFunction2 body
   }
}

Apply Transformation On

Select the source service, target service, or aggregator on which you want to apply the transformation.

Statistics

You can collect and monitor the following statistics:

Events Received
Bytes Received
Events Generated
Bytes Sent
Time Taken for Transformation (Milliseconds)

function transform(input, output, utility)
{
var string = utility.getString(input);
var textToAdd = "myString ";
var newString = textToAdd.concat(string);
output.write(utility.getBytes(newString));
}
