Package com.groiss.ds

The ds package contains some useful data structures and interfaces.

See: Description

Interface Summary

Interface	Description
KeyValuePair<K,V>	This interface is implemented by some classes like PersistantObject, which have a unique key (object id) and a value - the object itself or a string representation.

Class Summary

Class	Description
AlphanumericComparator	string-comparator which correctly sorts alphanumeric values
ComparablePair<F extends java.lang.Comparable<F>,S>	The comparable pair represents a pair of a key and a value.
CountedSemaphore	A CountedSemaphore (from Dijkstra) where waiting threads are handled in FIFO order.
JsonComparator	Compares json objects according to the passed attributes.
KeyedList<K,V>	This class implements an ordered map.
ListComparator	Compare two lists.
MapComparator
MultiMap<K,V>	A MultiMap maps keys to objects, where one key can be mapped to a list of objects.
ObjectTableModel	A table model implementation that allows objects as column names.
OrderedMap<K,V>	A map implementation where they keys are backed by a hashmap.
Pair<F,S>	A Pair is an object that contains two other objects.
PairComparator<K,V>	Use this comparator to sort Persistent objects or other KeyValuePairs.
StringExpression	An expression is parsed, the containing variables are substituted with values.
ThreadLocal2<T>	Same as java.lang.ThreadLocal, plus monitoring utility
Tree<D>	Simple N-ary Tree structure.
Triple<F,S,T>	A Triple is an object that contains three other objects.
TwoLevelMap<K1,K2,V>	HashMap based two-level Map.

Exception Summary

Exception	Description
QueueFullException	This Exception is thrown when the semaphore queue is full.
WouldBlockException	This Exception is thrown when an action will block the current thread.
