如何获得内容辅助“ for循环”。 Eclipse中的任何地方？ [英] How to get content assist for "for loop" anywhere in Eclipse?
问题描述
在Eclipse中，在这样的一行之后：
In Eclipse, after a line like this:
列表列表= new ArrayList（）;
List list = new ArrayList();
在下面键入 for，然后键入 ctrl-space（默认情况下），将带来几个有助于完成此 for循环的选项：
Typing "for" just beneath, and followed by "ctrl-space" (by default), will bring several options that can help completing this "for loop":
但是，如果声明变量 list的位置远离此处（例如，作为类字段），则可能无法从此上下文中直接推断出，或者声明了很多列表，那么该帮助无法正常工作：
But if the variable "list" is declared far from here (e.g. as a class field) which may not be directly inferred from this context, or there are many Lists declared,then the assistance doesn't work well:
@@分割线---
@@ split line ---
在某些情况下，Eclipse可以提供帮助，但不要不适用于成员变量。例如。手动键入另一个，并在：之后输入ENTER并不能说服Eclipse猜测它。...。
In some cases, Eclipse can assist, but just don't work for member variable. E.g. manually type "another" and ENTER after the ":" didn't persuade Eclipse to guess about it....
（PS适用情况：
自动猜测
输入想要的名称，然后按ENTER，效果很好
Entered wanted name, and ENTER, works great
）
有人有小费吗？要在这种情况下使此帮助有效？
Does anyone have any tip to make this assistance work under such scenarios?
推荐答案
我通常为解决for循环的内容帮助而做的事情如下：
What I usually do to solve the content assist with for loop is the following:
-
通过输入声明在上方的集合变量和分号来创建局部变量：
create a local variable by typing collection variable that is declared far above and a semicolon:
list;
按Ctrl + 2 L
press Ctrl+2 L
Eclipse生成一个新的局部变量声明，如下所示：
Eclipse generates a new local variable declaration which looks like this:
List list2 = list;
输入我的foreach并使用Ctrl + space自动完成，得到以下内容：
type my foreach and autocomplete with Ctrl+space getting the following:
List list2 = list;
for (Object object : list2) {
}
place将光标放在for循环声明中的list2上，然后按Alt + Shift + I表示内联变量。
place cursor on list2 in the for loop declaration and press Alt+Shift+I which stands for inline variable.
这将导致您想要实现。经过一些练习后，工作量很小：
this results in what you want to achieve. The effort is minimal after some practicing:
for (Object object : list) {
}
