All Implemented Interfaces:

ConfigurationElement, FileCache, org.adroitlogic.ultraesb.jmx.element.FileCacheMXBean, org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanNameAware

public class RAMDiskFileCache
extends org.adroitlogic.ultraesb.core.AbstractFileCache

A file cache optimized to manage temporary files created on a RAM disk. If the RAM disk overflows, the implementation will spill over to a normal disk based file cache.
