Class RecyclingSerialBinding

All Implemented Interfaces:

com.sleepycat.bind.EntryBinding

public class RecyclingSerialBinding
extends com.sleepycat.bind.serial.SerialBinding

A SerialBinding that recycles a single FastOutputStream per thread, avoiding reallocation of the internal buffer for either repeated serializations or because of mid-serialization expansions. (Cached stream's buffer will quickly grow to a size sufficient for all serialized instances.)
