public interface Accountable

An object whose RAM usage can be computed.

NOTE: This API is for internal purposes only and might change in incompatible ways in the next release.

Method Summary

Modifier and Type	Method	Description
default Collection<Accountable>	getChildResources()	Returns nested resources of this class.
long	ramBytesUsed()	Return the memory usage of this object in bytes.

Method Detail

ramBytesUsed

long ramBytesUsed()

Return the memory usage of this object in bytes. Negative values are illegal.

getChildResources

default Collection<Accountable> getChildResources()

Returns nested resources of this class. The result should be a point-in-time snapshot (to avoid race conditions).
