histogram objects vs dominator tree entries [message #904498]

I'm using MAT 1.2. While examining some heap dumps I noticed that for a particular class the dominator_tree shows 8,435 entries (242,152 filtered) and the Histogram shows the same class with 251,900 objects. Any ideas on why they are displayed differently and what entries mean compared to objects?

Thanks.

I believe I have found my answer. The 8,435 entries are the number of those specific objects (as seen when using a reg exp in the dominator_tree for a specified class name). The 251,900 objects represents the retained set that the 8,435 specific entries (instances of the specific class) keep around.
