IoEventSizeEstimator
public class DefaultIoEventSizeEstimator extends Object implements IoEventSizeEstimator
A defaultIoEventSizeEstimator
implementation.Martin's Java Notes was used for estimation. For unknown types, it inspects declaring fields of the class of the specified event and the parameter of the event. The size of unknown declaring fields are approximated to the specified averageSizePerField (default: 64).
All the estimated sizes of classes are cached for performance improvement.
