XClassLoaderHistogramRecord
public XClassLoaderHistogramRecord(String label, int classLoaderId, ArrayList<ClassHistogramRecord> classHistogramRecords, long numberOfObjects, long usedHeapSize, long retainedHeapSize) Create record for the class loader based on the records for the classes- Parameters:
label- for displayclassLoaderId- the object id of the class loaderclassHistogramRecords- summary of all the classes loaded by the class loadernumberOfObjects- the total number of objectsusedHeapSize- the total shallow size of the loader, classes and objectsretainedHeapSize- the total retained size of the loader, classes and objects

calculateRetainedSizein 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:
SnapshotException
