Class	Description
EconomicMap<K,V>	Memory efficient map data structure that dynamically changes its representation depending on the number of entries and is specially optimized for small number of entries.
EconomicMapUtil	Utility methods for the EconomicMap.
EconomicMapWrap<K,V>	Wraps an existing Map as an EconomicMap.
EconomicSet<E>	Memory efficient set data structure.
Equivalence	Strategy for comparing two objects.
LockFreePool<T>	Concurrent lock-free pool data structure.
LockFreePrefixTree	Thread-safe and lock-free prefix-tree implementation in which keys are sequences of 64-bit values, and the values are 64-bit values.
LockFreePrefixTree.Allocator	Policy for allocating objects of the lock-free prefix tree.
LockFreePrefixTree.HeapAllocator	Allocator that allocates objects directly on the managed heap.
LockFreePrefixTree.Node
LockFreePrefixTree.ObjectPoolingAllocator	Allocator that internally maintains several pools of preallocated objects, and allocates objects from those pools.
MapCursor<K,V>	Cursor to iterate over a mutable map.
Pair<L,R>	Utility class representing a pair of values.
SeqLockPrefixTree	Thread-safe prefix-tree implementation in which keys are sequences of 64-bit values, and the values are 64-bit values.
SeqLockPrefixTree.Node
UnmodifiableEconomicMap<K,V>	Unmodifiable memory efficient map.
UnmodifiableEconomicSet<E>	Unmodifiable memory efficient set data structure.
UnmodifiableMapCursor<K,V>	Cursor to iterate over a map without changing its contents.
