Class PropertiesBasedMetadataPersister

java.lang.Object
  org.springframework.integration.context.metadata.PropertiesBasedMetadataPersister

All Implemented Interfaces:

InitializingBean, MetadataPersister<String>

public class PropertiesBasedMetadataPersister
extends Object
implements MetadataPersister<String>, InitializingBean

Implementation of MetadataPersister that knows how to write metadata to a Properties instance. TODO could this perhaps participate or at least be aware of our transaction synchronization mechanism? IE: no guarantees, but we at least try to write on commit()s?
