Class MemsetEvaluator

java.lang.Object

org.apache.solr.client.solrj.io.eval.RecursiveEvaluator

org.apache.solr.client.solrj.io.eval.MemsetEvaluator

All Implemented Interfaces:

Serializable, StreamEvaluator, ValueWorker, Expressible

public class MemsetEvaluator
extends RecursiveEvaluator

The MemsetEvaluator reads a TupleStream and copies the values from specific fields into arrays that are bound to variable names in a map. The LetStream looks specifically for the MemsetEvaluator and makes the variables visible to other functions.
