calculateRetainedSize
public long calculateRetainedSize(ISnapshot snapshot, boolean calculateIfNotAvailable, boolean approximation, IProgressListener listener) throws SnapshotException Description copied from class:ClassLoaderHistogramRecord
Find out the retained size- Overrides:
calculateRetainedSize
in classClassLoaderHistogramRecord
- Parameters:
snapshot
- the snapshotcalculateIfNotAvailable
- whether to calculate the size if not already availableapproximation
- whether to use an approximation to the retained size (sum of the individual retained sizes)listener
- to report progress and errors- Returns:
- the retained size, negated if approximate, and 0 if unavailable
- Throws:
