Class PooledCodec

java.lang.Object
  org.szegedi.spring.web.jsflow.codec.PooledCodec

All Implemented Interfaces:

BinaryStateCodec

public class PooledCodec
extends java.lang.Object
implements BinaryStateCodec

A codec that can pool and reuse OneWayCodec instances of another codec it wraps. The pool uses soft references, and therefore plays nicely with regard to memory. It is recommended with codecs that can have high initialization overhead, i.e. a ConfidentialityCodec using password-based encryption, or a IntegrityCodec. When more than one of these are combined into a CompositeCodec, it is a good idea to wrap the composite codec with a pooled codec, instead of wrapping the individual component codecs.
