Eclipse debugging HashMap: Logical Structure using Key and Value's toString() method

Question

I have recently started to use Eclipse after using IntelliJ for a few years. When debugging Map using IntelliJ, if the key or object implements toString(), a nice list of string representation of key-value is displayed.

In Eclipse, when I select Show Logical Structure, I see something like the following:

The problem with this view is that you will need to expand each entry to see the actual key and value. If you need to find something in a map of more than 10 elements, it becomes very tedious.

I understand that you can make custom Logical Structure and the default for Map look the this:

return entrySet().toArray();

Is there any way, either through custom Logical Structure or plugin to view Map Entries more useful than

ConcurrentHashMap$WriteThroughEntry (id=193)

Answer 1

You need to create a detail formatter on top of the logical structure. In the example screenshot you provided, your logical structure is ConcurrentHashMap$WriteThroughEntry. You can add the detail formatter by right clicking on a row containing a ConcurrentHashMap$WriteThroughEntry and selecting 'add detail formatter'.

I just knocked up this example using HashMap.

java.util.HashMap$Entry //  key + " - " + value

For a

HashMap<Integer,String> map;

.. I quickly populated with rubbish, I now see:
