Android Studio HPROF参考树元素颜色代表什么? [英] What do the Android Studio HPROF reference tree element colours represent?

问题描述

有人可以告诉我Android Studio中HPROF Viewer中的粗体，蓝色1和红色1位置到底是什么意思吗?

Can someone tell me what does bold, blue one and red one positions in HPROF Viewer in Android Studio means exactly ?

我在参考树"面板中询问了一个.

I ask about one in Reference Tree panel.

最诚挚的问候.

推荐答案

我找不到关于此的任何文档，但是通过查看一些堆转储，它们似乎是这样的:

I can't find any documentation on this, but from looking through a few heap dumps this is what they seem to be:

• blue-最接近顶部的实例的统治者右窗格.
• bold-GC根，例如，应该收集 not 的深度为0的实例. 此答案具有有关GC根目录是什么的更多信息，并且

• blue - The closest dominator of the instance selected in the top-right pane.
• bold - A GC root, eg an instance with depth 0 that should not be collected. This answer has more information on what a GC root is, and this answer lists the types of things that are roots.
• red - I haven't actually seen these, but I would guess it indicates an instance that should be garbage collected, but hasn't been yet.

再次，这里的免责声明是这可能都是错误的，并且我实际上找不到任何官方信息，但这似乎与我在使用堆探查器时的观察结果相符.

Again, a disclaimer here is that this could all be wrong and I can't actually find any official information about this, but it does seem to match up with my observations when using the heap profiler.
