Class FieldInitMover

java.lang.Object
  at.dms.kjc.sir.EmptyStreamVisitor
      at.dms.kjc.sir.lowering.FieldInitMover

All Implemented Interfaces:

StreamVisitor

public class FieldInitMover
extends EmptyStreamVisitor

This class converts joint field definition/assignment statements to a field decl and a corresponding field assignment statement in the init function. Eg

 int i = 5;
 

into

 int i;
 i = 5;
