java.lang.Object

org.apache.flink.table.codesplit.DeclarationRewriter

所有已实现的接口:

CodeRewriter

@Internal
public class DeclarationRewriter
extends Object
implements CodeRewriter

Extract and rename local variables into member variables.

This rewriter only deals with functions without return values. Functions with return values should have been converted by ReturnValueRewriter.

Before

 public class Example {
     public void myFun1(int[] arr) {
         int a = 1;
         for (int b : arr) {
             System.out.println(b);
         }
     }
     public void myFun2() {
         int a = 2;
     }
 }
 

After

 public class Example {
     int a;
     int local$0;
     int local$1;
     public void myFun1(int[] arr) {
         a = 1;
         for (int b : arr) {
             local$0 = b;
             System.out.println(local$0);
         }
     }
     public void myFun2() {
         local$1 = 2;
     }
 }
