Calculate Naive Retained Heap Size

Calculates all of the objects retained (referenced) by a given object, ignoring the fact that some of those objects might also be referenced by other parts of the application.

Naively sum the shallow heap sizes of all outgoing references of an object. This may be useful if you know that some object is self-contained and the 'source' of all outgoing references, but that some other object(s) have references into said object's graph (therefore, its retained heap will not include the retained heaps of those references). A similar analysis can be done using a Customized Retained Set with an exclude list.
