How to use Eclipse Memory Analyser Tool (MAT) for analysing a hashmap

Question

I am facing a memory leak. So, I captured a heap dump for my application, and am trying to analyse it using Memory Analyser Tool (MAT). I clicked on Heap Dump Overview option in the menu of hprof file. Then , clicked on Class Histogram. It showed me a list of all objects, grouped by class, taking up the maximum meory. One of which is my cutom hashmap. Now, I want to analyse the entries of this hashmap.

Any idea how I can do so ? If I click on the custom hashmap name, then click on List Objects->with incoming references, it just shows list of all objects in the hashmap & the hierarchy by which these objects was created, & not the actual key-value pairs for the hashmap entries.

P.S. My custom Hashmap:

private Hashmap<Integer, TextCache> mCache;

class TextCache{
    Bitmap bitmap;
    int left;
    int right;
    int keyCode;
}

To answer my own question, I was trying to view the hprof file from Java/Debug Perspective. When I switch to Memory Analysis perspective, I could view the details of all objects, including key-value pairs for hashmap entries, in an Inspector -> Attributes window towards the left.

Edit: "key" attribute of the hashmap entries are still not visible. Only attributes of my custom hashmap entry object, which is the "value" part are visible. So, what I did is, for testing purpose, I put the key attribute (which is an integer), in the custom hashmap entry object, to be able to view it from the Inspector -> Attributes from the Memory Analysis perspective.

class TextCache{
    Bitmap bitmap;
    int left;
    int right;
    int keyCode;
    int key; // this is actually the key used to insert objects of TextCache into the hashmap.
}

If anybody finds out, how to directly view the "key" part from the hprof file, it would be great.
