在Eclipse Debugger（for Java）中，有没有办法检查任意值？

Question

I'm wondering if there is a way to look at the values of non-declared variables as they get passed into a function, after that function has been executed . For example, if I am debugging and the line

foo.setBar(baz.getBar());

has already been passed (but is still within scope), how can I see the value of what got passed in to setBar() ? I know that I can see this many other ways, for instance by stepping into the setBar() call, or by assigning baz.getBar() to a temporary variable - but that's not what I'm asking.

Edit: Basically, I feel penalized (by losing the ability to see certain information) while debugging, just because I'm not declaring every variable.

And, I know I could inspect bar after the fact (if I know it hadn't changed) but in this case it's not so simple because I'm dealing with objects that aren't just POJOs or JavaBeans (the object that brought this question up is an HTTP request - and yes, I already did try inspecting it).

Answer 1

在Debug透视图中，打开显示窗口（Window => Show View => Display），编写要显示的代码（例如， baz.getBar() ），选择它，然后右键单击并选择“Display”或使用快捷方式显示其值。

Answer 2

A by far easier way is to select an expression (here: baz.getBar()) and press CTRL+SHIFT+I (for inspect). This opens a tooltip like window with all you want to know.

Answer 3

当然，您可以使用“表达式”视图（窗口 - >显示视图 - >表达式）。

Answer 4

in your Expressions view, add the following expression

baz.getBar()

and it will be dispayed while debugging (if it is visible to the debugger ofcourse)
