Class KeyValueRemover  

java.lang.Object
  com.trapezium.chisel.Optimizer
      com.trapezium.chisel.cleaners.InterpolatorMinimizer
          com.trapezium.chisel.cleaners.KeyValueRemover

public class KeyValueRemover

extends InterpolatorMinimizer

The KeyValueRemover removes keys and corresponding keyValues if the following conditions are encountered: 1. a key of the form: ... a a a .... ^ this middle value (one or more) and corresponding keyValue entries are removed. 2. a keyValue of the form ... a a a .... ^ this middle keyValue (one or more) and corresponding key entries are removed.
