Class	Description
ArrayIterator<T>	an Iterator of array elements
ArrayNonNullIterator<T>	Iterator that only returns non-null elements of the array
ArraySet<T>	A set implementation backed by an array.
ArraySetMultiMap<K,V>
BimodalMap<K, V extends @Nullable Object>	This implementation of Map chooses between one of two implementations, depending on the size of the map.
CollectionFilter<T>	A filter defined by set membership
ComposedIterator<O,I>	A 2-level iterator.
CompoundIntIterator	An Iterator which provides a concatenation of two IntIterators.
CompoundIterator<T>	An iterator which provides a logical concatenation of the lists from two other iterators
EmptyIntIterator	A singleton instance of an empty iterator; this is better than Collections.EMPTY_SET.iterator(), which allocates an iterator object;
EmptyIterator<T>	A singleton instance of an empty iterator; this is better than Collections.EMPTY_SET.iterator(), which allocates an iterator object;
Factory<T>
FifoQueue<T>	FIFO work queue management of Objects that prevents an object from being added to the queue if it is already enqueued and has not yet been popped.
FifoQueueNoDuplicates<T>	FIFO work queue management of Objects that prevents an Object from being added to the queue if it was ever previously enqueued.
FilterIterator<T>	A FilterIterator filters an Iterator to generate a new one.
Filtersection<T>	intersection of two filters
HashMapFactory	A debugging aid.

Heap<T>	Simple Heap data structure.
ImmutableStack<T>	An immutable stack of objects.
IndiscriminateFilter<T>	A filter that accepts everything.
IntMapIterator<T>	An IntMapIterator maps an Iterator contents to produce a new Iterator
IntStack	A stack of integer primitives.
Iterator2Collection<T>	Converts an Iterator to a Collection.
Iterator2Iterable<T>	Converts an Iterator to an Iterable.
Iterator2List<T>
Iterator2Set<T>
IteratorPlusOne<T>	A utility to efficiently compose an iterator and a singleton
IteratorPlusTwo<T>
IteratorUtil	utilities dealing with Iterators
IVector<T extends @Nullable Object>	simple interface for a vector.
MapIterator<X,Y>	An MapIterator maps an Iterator contents to produce a new Iterator
MapUtil	utilities for managing Maps
MultiMap<K,V>
NonNullSingletonIterator<T>	A singleton iterator for an object which is guaranteed to be not-null.
ObjectArrayMapping<T>	A bit set mapping based on an immutable object array.
ObjectVisitor<T>
Pair<T,U>
ParanoidHashMap<K,V>	a debugging aid.
ParanoidHashSet<T>	a debugging aid.
ReverseIterator<T>	An iterator that reverses an input iterator.
SimpleVector<T>	simple implementation of IVector
SmallMap<K, V extends @Nullable Object>	A simple implementation of Map; intended for Maps with few elements.
SparseVector<T extends @Nullable Object>	An IVector implementation designed for low occupancy.
ToStringComparator<T>	A comparator based on lexicographical ordering of toString()
TwoLevelVector<T extends @Nullable Object>	An IVector implementation which delegates to pages of int vectors.
Util	Miscellaneous utility functions.
