Memory Analyzer uses several indexes to enable access to different parts of the snapshot.
- IDENTIFIER
- IntToLong - object ID to object address
- O2CLASS
- object ID to class ID
- A2SIZE
- array object ID (or other non-fixed size object) to encoded size (32-bits)
- INBOUND
- object ID to list of object IDs
- OUTBOUND
- object ID to list of object IDs
- DOMINATED
- Dominated: object id to N dominated object ids
- O2RETAINED
- object ID to long
- DOMINATOR
- Dominator of: object id to the id of its dominator
- I2RETAINED
- cache of size of class, classloader (read/write)
