Groovy reference

Ziggizag

Hi,

It seems it is impossible to find Groovy lang scripting reference for RapidMiner.
Is it available? How to know what packages are implemented and how to access them?

I cannot find any clue how to use JsonOutput class in Execute Stript object!

But my question is general - where the hell is the scripting guide???

Hi,

if you plan to do any complex coding it might be easier to just write an extension (and then copy a code snippet from there into an Execute Script operator if needed).

Do you mean this JsonOutput class?

https://github.com/apache/groovy/blob/master/subprojects/groovy-json/src/main/java/groovy/json/JsonOutput.java

Either import the class via

import groovy.json.JsonOutput
JsonOutput.toJson(new java.util.Date())

or use the fully qualified name to access the class

groovy.json.JsonOutput.toJson(new java.util.Date())
