Description

Interface Summary

IIdProvider<I,T>	This interface defines an ID provider.
ISortableData	Abstraction for sortable/comparable data.

Class Summary

AllEqualComparator<T>	Comparator that does not acutally compare but handles all elements as being equal.
ArrayBackedMap<K,V>	A map implementation based on unsorted arrays.
ArrayBackedStringMap<V>	A specialization of the array backed map for string keys.
ArrayUtils	Utility methods for arrays.
BidirectionalMap<S,T>	A collection which implements a bidirectional mapping.
ClassHierarchyMap<T,V>	This class provides a mapping from classes to values.
CollectionUtils	This class offers utility methods for collections.
CounterSet<E>	This class manages a set of counters (i.e. is a mapping from some key objects to integers).
HashedListMap<K,I>	This class defines a mapping from on item to a list of items.
HybridMapBase<K,V>	A hybrid map is a map which starts with one map implementation, but switches to another one after a certain size is reached.
IdComparator<I extends Comparable<I>,T>	Comparator that compares objects based on the identifiers provided by a IIdProvider.
IdentifierBasedComparatorBase<I extends Comparable<I>,T>	Base class for comparators that compare to objects by comparing a suitable object identifier.
IdentityHashSet<E>	This class implements a set based on referential equality similar to JDK class IdentityHashMap.
IdentityPairMap<T,V>	A map using (unordered) pairs as key which are compared by reference.
IdManager<K>	This class assigns unique ids to objects.
IdManagerBase<K>	Base class for id managers.
ImmutablePair<S,T>	Simple readonly pair class.
IntList	A really simple list for storing ints.
InvertingComparator<E>	This works on another compartor and inverts it.
ManagedIntArray	A class containing an int array that is managed in the sense that it can grow dynamically (using exponential growth).
MemoryEfficientStringMap<V>	A map implementation of a map using string keys.
Pair<S,T>	Simple pair class.
PairList<S,T>	A list for storing pairs in a specific order.
SortableDataUtils	Abstraction for sortable/comparable data.
SortedCounterSet<E extends Comparable<? super E>>	A counter set supporting ranged access to its values, i.e. it is possible to query the sum of values for all keys in a given range.
StringLengthComparator	Compares strings by their length.
ToStringComparator	This comparator compares objects by their toString() representation.
TwoDimHashMap<K1,K2,I>	A 2-dimensional hash map.
UniqueIdManager<K>	This class assigns unique ids to objects.
UnmodifiableCollection<E>	This is a wrapper for a Collection prohibiting all calls which would modify its contents.
UnmodifiableHashedListMap<K,I>	This is a wrapper for a HashedListMap prohibiting all calls that would modify its contents.
UnmodifiableIterator<E>	This is a wrapper for a Iterator prohibiting all calls which would modify its owning container.
UnmodifiableList<E>	This is a wrapper for a List prohibiting all calls which would modify its contents.
UnmodifiableListIterator<T>	This is a wrapper for a ListIterator prohibiting all calls which would modify its owning container.
UnmodifiableMap<K,V>	This is a wrapper for a Map prohibiting all calls which would modify its contents.
UnmodifiableSet<E>	This is a wrapper for a Set prohibiting all calls which would modify its contents.
UnmodifiableSortedMap<K,V>	This is a wrapper for a SortedMap prohibiting all calls which would modify its contents.
UnmodifiableSortedSet<E>	This is a wrapper for a SortedSet prohibiting all calls which would modify its contents.
