Nested Class Summary

Nested Classes

Modifier and Type	Class	Description
class	SerializationMeasures.AllStatDetails	each instance of this class remembers a set of statDetail instances to do bulk operations against that set of the statistics
static class	SerializationMeasures.StatDetail	Statistical details There's instances of this class for - the main heap - the aux heaps - the string offsets, the string lengths Heap: xxxx [name-of-delta: [Total: <TotalBytes>(negative%) Histo: a(neg%) b(neg%) c(neg%) d(neg%) e(neg%)]] 2 styles: one uses only one counter, no delta - used for byte, short, and long heaps other is for main heap, uses 4 deltas.
