Class DefaultMessageSizeEstimator

java.lang.Object
  org.red5.server.net.filter.DefaultMessageSizeEstimator

All Implemented Interfaces:

IoEventSizeEstimator

public class DefaultMessageSizeEstimator
extends Object
implements IoEventSizeEstimator

A default MessageSizeEstimator implementation.

Martin's Java Notes were used for estimation of the size of non-IoBuffers. For unknown types, it inspects declaring fields of the class of the specified message. 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.
This originated from the Mina sandbox.
