## Class CPlanOpRewriter

- java.lang.Object
- - org.apache.sysds.hops.codegen.template.CPlanOpRewriter

-     public class CPlanOpRewriter
      extends Object

  This cplan rewriter is meant to be the central place for any cplan enhancements before code generation. These rewrites do not aim to handle reorderings or other algebraic simplifications but rather focus on low-level simplifications to produce better code, while keeping the cplan construction of the individual templates clean and without unnecessary redundancy. Assumption: This rewriter should be called before CSE as these rewrites potentially destroy common subexpressions.
