java/eclipse中的数据断点
当使用 VS 开发 C++ 时，您会遇到数据断点这一令人惊奇的功能，当内存中某个地址的数据发生变化时，就会触发断点。
在eclipse中开发java有类似的功能吗？
谢谢！
编辑：关于“值更改时暂停”功能：我的印象是执行仍然必须到达断点所在的行。问题是我希望它在值发生变化时立即在任何地方触发。
when developing C++ with VS you have this amazing feature of data breakpoints, which trigger when the data at a certain address in memory changes.
is there a similar feature when developing java in eclipse?
thanks!
edit: about the "suspend when value changes" feature: i have the impression that the execution must still reach the line where the breakpoint is. the thing is i want it to trigger anywhere as soon as the value changes.

您可以在字段上设置观察点：将光标放在声明字段的行上，然后选择菜单
Run ->切换观察点或者只需双击该行的左边距即可设置断点。
添加观察点后，您可以更改观察点的属性，例如
在字段访问时暂停或在字段修改时暂停。只需右键单击左侧边距的观察点并选择Breakpoint Properties...搜索观察点的帮助以获取更多信息：
You can set a watchpoint on a field: put the cursor at the line where the field is being declared and select the menu
Run -> Toggle Watchpointor just set a breakpoint by double-clicking at the left margin on that line.
You can change the properties of the watchpoint like
suspend on field accessorsuspend on field modificationafter adding it. Just right-click on the watchpoint at the left margin and selectBreakpoint Properties...Search the help for watchpoint to get more information:
使用变量视图：
请注意，性能可能不如内存硬件断点（例如在 VC++ 中）。
Using the Variable view:
Note that the performance is probably not as good as with a memory hardware breakpoint (like in VC++ for example).
在断点属性下，您可以选择将其设置为有条件并选中单选按钮“值更改时暂停”。
Under breakpoint properties, you have the option of making it conditional and checking the radio button "Suspend when value changes".
右键单击断点并选择
断点属性。在打开的屏幕中，选择：
Conditional ->当值改变时暂停Right click on the Breakpoint and select
Breakpoint properties.In the opening screen, choose:
Conditional -> Suspend when value changes最接近的是编辑断点属性。您可以添加条件来检查不同的值。另一种方法是向 setter 方法添加断点。
您可以通过右键单击断点视图中已设置的断点来设置断点属性。
The closest thing would be editing the breakpoint properties. You could add conditions to check for distinct values. Another way could be adding a breakpoint to the setter method.
You can set the breakpoint properties by right-clicking on an already set breakpoint in the breakpoint view.
据我所知，Eclipse 中没有这样的通用功能。但是，您可以为现有断点指定一些条件：
在代码中的某处添加断点。然后，在“断点”视图中右键单击它，然后选择“断点属性”。在面板中，您可以添加必须验证的条件，以使应用程序在此断点处停止（例如
if (foo > 0)）。这并不完全是你想要的，但我不认为 Eclipse 提供这样的功能。
As far as I know, there is no such generic feature in Eclipse. However, you can give some conditions to an existing breakpoint:
Add a breakpoint somewhere in your code. Then, in the "Breakpoint" view, right click on it, then choose "Breakpoint properties". In the panel, you can add a condition that must be verified to make the application stops on this breakpoint (for example
if (foo > 0)).This is not exactly what you want, but I do not think Eclipse provides such feature.
