java.lang.Object

com.neurosys.etl.common.transformers.GenerateListTransformer

All Implemented Interfaces:

FunctionTransformer, Function, org.apache.commons.collections.Transformer

public class GenerateListTransformer
extends Object
implements FunctionTransformer

Generate a List or Array from a given input
