Description

https://hop.apache.org/manual/next/pipeline/transforms/userdefinedjavaclass.html is very sketchy.

Questions I have:

• if it's a class, which method(s) is (are) called to do the work?
• how do these methods access the input fields?
• Provide an example of such custom class

Questions on Options:

• "Info transforms": shouldn't this be "Source transforms" or "Input transforms"?
• "Info transforms" and "Target transforms": can both of these be multiple? If so, explain it
• What is "Tag" in relation to the Input and Target transforms?
• "Info transforms" and "Target transforms": the "userdefinedjavaclass" transform is placed on the canvas and connected to some transforms. Then why are these included in the Options?
• "Test class": what exactly happens?
