Process of Creating Custom Transformer

1. Creating Custom
Transformer
- By Rahul Kumar

2. Creating Custom Transformer
Create your own Filter implementation by
Implementing org.mule.transformer.AbstractTransformer interface
Overriding the standard implementations of org.mule.transformer.AbstractTransformer like
org.mule.transformer.codec.Base64Encoder,
org.mule.transformer.simple.ObjectToString,
org.mule.transformer.simple.ObjectToOutputHandler and many mores

3. Snippet for Custom
Transformer
package org.rahul.mule.transformer;
import org.mule.api.transformer.TransformerException;
import org.mule.transformer.AbstractTransformer;
public class KeyTransformer extends AbstractTransformer {
@Override
protected Object doTransform(Object src, String enc)
throws TransformerException {
return "Hello " + src.toString().substring(1);
}
}

4. Snippet for Custom
Transformer
The snippet shown will create a Transformer which will ado simple String
operations on the original payload and return the modified payload

5. Configuration
Provide this class in Custom Transformer component from the palette.
Your custom Transformer is now ready to use!
