pullupmethod.java

emacs的一个非常有用的插件,叫xrefactory,可以实现source insight里的那种函数跳转.和cscope(跳回来不方便)配合使用,非常的不错.

package com.xrefactory.refactorings;

/*
  1.)   Put  cursor inside  PullUpMethod  class  and  invoke 'Xref  ->
  Refactor'. Select 'Set Target  for Next Moving Refactoring' from the
  proposed menu.

  2.)  Move  cursor onto  the definition of  the method to  move (onto
  'method' name), invoke 'Xref ->  Refactor' once more time and select
  'Pull Up Method'.

class PullUpMethod {
    int x = 0;
    int y = 0;
    // set target here:

}

class InferClass extends PullUpMethod {
    int y = 1;

    // put cursor on 'method' name
    void method() {
        System.out.println("x == " + x);
        System.out.println("this.x == " + this.x);
        System.out.println("this.y == " + this.y);
