Interface Summary
Comparer | This interface is the thing used by QSort to compare two objects.
MemoryPressure |
Preferences | This is an interface to get things from the Preferences database.

Class Summary
Abacus | A class for counting in a variety of bases.
ArrayEnumeration |
Assert | Simple assertion class that throws exceptions when an assertion fails.
Atom | Atom's are unique objects that you can use the object address to perform equality tests.
AtomHashtable | Special hashtable that uses Atoms as keys.
AttributeValuePair | Simple attribute/value pair class XXX add in a recylcer XXX add in a method to reconsitute one from an InputStream/String?
ByteBuf | This class is similar to java/lang/StringBuffer with the following changes: Stores bytes, not chars None of the methods are synchronized There is no sharing of the character array Converting to a String requires a copy of the character data Alloc and Recycle are provided to speed up allocation A bunch of useful operations are provided (comparisons, etc.)
ByteLineBuffer | This class is stores data in a private ByteBuf appending new data as needed, and returning line separated data.
ByteToCharConverterEnumeration |
CacheOutputStream | This class provides buffering for arbitrarily large streams of data.
CharArray |
CharArrayIterator |
CharToByteConverterEnumeration |
ClasspathEntryEnumeration |
ConfigUtils |
Counter | Like Integer except the value is mutable
DefaultPreferences |
EnumerationEnumerator |
HashtableLite | A utility class to avoid the pain (and memory bloat) of making lots of small hashtables.
HashtableRecycler | Static recycler class for java.util.Hashtable
IDMap | An identifier mapper.
LineBufferingInputStream |
ListenerList | ListenersList is a thread-safe, reentrant class which contains a list of EventListeners and enforce some policy on event dispatching.
ListenerListState | ListenersListState keeps the index into the array of listeners for the ListListeners class.
MemoryManager |
MemoryMonitor | A utility class to help track memory usage during development.
NetworkDate | Parses a date out of a string of bytes.
NullEnumeration |
NullJavaEnumeration |
PreferencesFactory | A factory to return the (singleton) preferences object.
PrefetchEnumeration |
QSort | Implements QuickSort, on an array of objects.
RandomAccessFileWithByteLines |
Recycler |
RWLock | A "read-write" lock.
SelfTest | SelfTest for calypso.util package
SignedInteger | Utility class that represents the parse state from parsing a signed integer.
StringBuf | This class is similar to java/lang/StringBuffer with the following changes: None of the methods are synchronized There is no sharing of the character array Converting to a String requires a copy of the character data Alloc and Recycle are provided to speed up allocation A bunch of useful operations are provided (comparisons, etc.)
StringUtils |

URLClassLoader | A URL based class loader.
Vec | Some more methods for Vector
VectorRecycler | Static recycler class for java.util.Vector
WeakLink | Weak link class.
WeakLinkArray | An array of objects whose references are weak.
