Class Summary

Class	Description
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.
CharacterChecker.WhitespaceChecker
Classes	A collection of Class utilities.
Counter	An integer counter class.
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.
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
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

Exception	Description
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.
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

Error	Description
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.
