Class LookupChain

java.lang.Object

com.neurosys.etl.common.TransformerChain

com.neurosys.etl.common.LookupChain

All Implemented Interfaces:

Chain, Lookup, FunctionTransformer, Serializable, Consumer, Function, Supplier, org.apache.commons.collections.Transformer

public class LookupChain
extends TransformerChain
implements Lookup, Chain

Allow chaining of multiple Lookups
TransformerChain.isChainOutput() is ignored for this implementation, as lookup operations are sequential and the next depends on previous.
