Operator Chains

simon_knoll

Hello all,
im trying to create a Minig process with the javaApi of rapidminer

but in the moment im stuck with the operator chain. javadoc says me

An OperatorChain is an Operator that contains children which are again Operators and which it can execute once ore several times during its own execution.
As of RapidMiner 5.0, an OperatorChain does not directly contain nested Operators, but rather nested ExecutionUnits which in turn contain operators. Please refer to the RapidMiner tutorial for a description how to implement your own operator chain. 

but i cannot find any tutorials regarding operatorchains
any advice?

regards
simon knoll

Hi,

there is an example in the "How to Extend Rapidminer" whitepaper found here:

Cheers,
