public class FileAppendStreamLRUCache
extends ResourceLimitedMap<java.io.File,java.io.OutputStream>

LRU cache of OutputStreams to handle situation in which it is necessary to have more FileOutputStreams than resource limits will allow. Least-recently-used FileOutputStream is closed when it is pushed out of the cache. When adding a new element to the cache, the file is opened in append mode. Actual elements in the cache are usually BufferedOutputStreams wrapping the FileOutputStreams, but will be FileOutputStreams if Defaults.BUFFER_SIZE = 0.
