| Interface | Description | 
|---|---|
| ConcurrentLRUCache.EvictionListener<K,V> | |
| StreamCharBuffer.LazyInitializingWriter | Interface for a Writer that gets initialized if it is used
 Can be used for passing in to "connectTo" method of StreamCharBuffer | 
| Class | Description | 
|---|---|
| _ComponentUtils | |
| Assert | |
| BiLevelCacheMap | A bi-level cache based on HashMap for caching objects with minimal sychronization
 overhead. | 
| ClassUtils | |
| CommentUtils | This class contains utility methods to detect special cases to be handled on "script" or
 "style" tags by HtmlResponseWriterImpl. | 
| ConcurrentLRUCache<K,V> | A LRU cache implementation based upon ConcurrentHashMap and other techniques to reduce
 contention and synchronization overhead to utilize multiple CPU cores more effectively. | 
| ConcurrentLRUCache.Stats | |
| ExceptionUtils | Various helpers to deal with exception | 
| FastWriter | StringWriter cannot be reused without create a new object over and over. | 
| HashMapUtils | |
| MyFacesObjectInputStream | Tried to deploy v0.4.2 on JBoss 3.2.1 and had a classloading problem again. | 
| NullEnumeration | Enumeration without elements | 
| NullIterator<T> | Iterator without elements | 
| PriorityQueue<T> | A PriorityQueue maintains a partial ordering of its elements such that the
 least element can always be found in constant time. | 
| RestoreStateUtils | |
| StateUtils | This Class exposes a handful of methods related to encryption,
 compression and serialization of the view state. | 
| StreamCharBuffer | 
 StreamCharBuffer is a multipurpose in-memory buffer that can replace JDK
 in-memory buffers (StringBuffer, StringBuilder, StringWriter). | 
| StringCharArrayAccessor | Provides optimized access to java.lang.String internals
 - Optimized way of creating java.lang.String by reusing a char[] buffer
 - Optimized way of writing String to java.io.Writer
 java.lang.String creation reusing a char[] buffer requires Java 1.5+
 System property "oam.stringchararrayaccessor.enabled" enables this hack. |
