Unit of retained heap in eclipse?

Question

I am getting numeric value of 1294736 in 'retained Heap' column when I use Memory Analyzer in Eclipse-Helios, what is the unit of this numeric value ? is it bytes or kBytes?

Same query for shallow heap value.

Answer 1

I had the same question. It seems to be in bytes. You can confirm this by writing a simple java program that repeated add stuff to a list, then run it with "java -Xmx2m -XX:+HeapDumpOnOutOfMemoryError" to max its heap usage to 2M, and dump the heap when it becomes full, then load the hprof file into the tool to verify.

I can verify that indeed it is in bytes based on my observations and analysis. – Kisung
