Interface Summary

CachePolicy	Interface that specifies a policy for caches.
CloneableObject.Cloneable	An interface which exposes a public clone method, unlike Object.clone() which is protected and throws exceptions...
Coercible	An iterface which an object implements to indicate that it will handle coercion by itself.
Executable	Interface for the execution of a task.
JBossInterface	Clone the object without throwing a typed exception.
NestedThrowable	Interface which is implemented by all the nested throwable flavors.
PrettyString	A simple interface for objects that can return pretty (ie.
PrettyString.Appendable	Interface for appending the objects pretty string onto a buffer.
Sync	Interface that gives synchronization semantic to implementors
ThrowableHandler.Type	Container for throwable types.
ThrowableListener	An interface used to handle Throwable events.
TimedCachePolicy.TimedEntry	The interface that cache entries support.
WaitSync	Interface that gives wait - notify primitives to implementors.

Class Summary

AbstractNestedThrowable	A common superclass for Throwable classes that can contain a nested Throwable detail object.
Base64	Encodes and decodes to and from Base64 notation.
Base64.InputStream	A Base64.InputStream will read data from another java.io.InputStream, given in the constructor, and encode/decode to/from Base64 notation on the fly.
Base64.OutputStream	A Base64.OutputStream will write data to another java.io.OutputStream, given in the constructor, and encode/decode to/from Base64 notation on the fly.
Classes	A collection of Class utilities.
CloneableObject	A simple base-class for classes which need to be cloneable.
CollectionsFactory	Collections factory.
Counter	An integer counter class.
DirectoryBuilder	A simple utility to make it easier to build File objects for nested directories based on the command line 'cd' pattern.
FieldInstance	A FieldInstance refers to a specific reflected field on an object.
HashCode	A hash-code generator and a collection of static hash-code generation methods.
Heap	Data structure that mantains data in a ordered binary tree; each node is greater (smaller) or equal than its 2 sub-nodes, for all the hierarchy.
JBossObject	Utility Class Utility Class that provides a Logger instance (log) and caching of toString() and hashCode() values.
JBossStringBuilder	A JBossStringBuilder, providing the same functionality as the java5 StringBuilder, except no Appendable which is java5 specific.
LongCounter	A long integer counter class.
LRUCachePolicy	Implementation of a Least Recently Used cache policy.
MethodHashing	Create a unique hash for
NestedThrowable.Util	Utilitiy methods for the various flavors of NestedThrowable.
Null	A class that represents null.
Objects	A collection of Object utilities.
Primitives	Primitive utilities.
Semaphore	Semaphore that can allow a specified number of threads to enter, blocking the others.
SoftObject	Convenience class to wrap an Object into a SoftReference.
StackTrace	Provides access to the current stack trace by parsing the output of Throwable.printStackTrace().
StackTrace.Entry	A stack trace entry.
StackTrace.Parser	A parser which takes a standard Throwable and produces StackTrace.Entry objects.
StopWatch	Simulates a stop watch with a lap counter.
StringPropertyReplacer	A utility class for replacing properties in strings.
Strings	A collection of String utilities.
Strings.Range	Represents a range between two integers.
SynchronizedCachePolicy	A synchronized cache policy wrapper.
ThrowableHandler	A static singleton that handles processing throwables that otherwise would be ignored or dumped to System.err.
Throwables	A collection of Throwable utilities.
TimedCachePolicy	An implementation of a timed cache.
TimerQueue	This class runs in a single thread TimerTasks that have been scheduled.
TimerTask	A class that represent a task that can be scheduled for one-shot or repeated execution by a TimerQueue.
WaitSemaphore	Wait exclusive semaphore with wait - notify primitives
WeakClassCache	A weak class cache that instantiates does not a hold a strong reference to either the classloader or class.
WeakObject	Convenience class to wrap an Object into a WeakReference.
WorkerQueue	Class that queues Executable jobs that are executed sequentially by a single thread.

Exception Summary

CoercionException	This exception is thrown to indicate that a problem has occured while trying to coerce an object.
DataConversionException	An exception throw to indicate a problem with some type of data conversion.
EmptyStringException	Thrown to indicate that a string was empty (aka.
NestedException	A common superclass for Exception classes that can contain a nested Throwable detail object.
NestedRuntimeException	A common superclass for RuntimeException classes that can contain a nested Throwable detail object.
NestedSQLException	A common superclass for SQLException classes that can contain a nested Throwable detail object.
NoSuchMethodException	A better NoSuchMethodException which can take a Method object and formats the detail message based on in.
NotCoercibleException	This exception is thrown to indicate that an object was not coercible.
NotImplementedException	Thrown to indicate that a method has not been implemented yet.
NullArgumentException	Thrown to indicate that a method argument was null and should not have been.
UnreachableStatementException	Thrown to indicate that section of code that should never have been reachable, has just been reached.

Error Summary

NestedError	A common superclass for Error classes that can contain a nested Throwable detail object.
UnexpectedThrowable	Thrown to indicate that a Throwable was caught but was not expected.
