Interface Summary

Counter	A simple interface encapsulating some dynamic integer greater than or equal to zero
Equality<E>	This interface declares a method which defines equality been objects of type E
Factory<E>	This interface defines an arbitrary object factory that requires no arguments.
Filter<E>	Defines a simple filter over objects
FilterPartialOrder<P>	This interface is used to define an abstract filter over a data set whose type is known but whose ordering may not be.
Function<X,Y>	The interface declares a method defining a function from domain X to range Y
Rehasher	A simple interface defining custom re-hashing functions

Class Summary

Counters	Some default Counter implementations
Counters.DontCounter	a Counter which ignores all updates to its value and always returns a value less than zero.
Counters.SerialCounter	Returns a regular Counter which performs ordinary addition with no concurrency guarantees
Counters.ThreadSafeCounter	a thread safe Counter which uses compare and set operations to modify its value
Equalities	Default implementations of Equality.
Equalities.ByteArrayEquality	an Equality over objects of type byte[], delegating to java.util.Arrays.equals(a, b) and java.util.Arrays.hashCode(k)
Equalities.CaseInsensitiveEquality	an Equality over String for case insensitive equality (a.equalsIgnoreCase(b)); hash() is expensive to compute as it performs toLowerCase().hashCode()
Equalities.EntryEquality<K,V>	an Equality over objects of type Entry, for provided K and V; wraps a separate Equality for comparing the key and value portions of the Entry.
Equalities.IdentityEquality	an Equality for identity equality, i.e.
Equalities.IntArrayEquality	an Equality over objects of type int[], delegating to java.util.Arrays.equals(a, b) and java.util.Arrays.hashCode(k)
Equalities.LongArrayEquality	an Equality over objects of type long[], delegating to java.util.Arrays.equals(a, b) and java.util.Arrays.hashCode(k)
Equalities.ObjectArrayEquality	an Equality over objects of type Object[], delegating to java.util.Arrays.equals(a, b) and java.util.Arrays.hashCode(k)
Equalities.ObjectEquality	Standard object equality, delegating to Object.equals() and Object.hashCode(), but handling nulls gracefully
Equalities.RehashingEquality<V>	an Equality which delegates to the provided Equality, but passes the resulting hash() through the provided Rehasher before returning it
Factories	A class providing methods acting on factories, and default factory implementations
Factories.CastFactory<E>	A simple factory which wraps another factory (ordinarily a SimpleObjectFactory) and (unsafely) casts the result to the type parameter provided.
Factories.SimpleObjectFactory<E>	A simple factory that creates objects of the type of the class provided, providing it has an empty constructor
Filters	A class providing methods acting on filters, and default filter implementations
Functions	A class defining simple functions, and methods for working with functions
Functions.AbstractValueProjection<E extends Value<V>,V>	A function that retrieves the value from a Value
Functions.FieldProjection<E,F>	A Function which accepts a Field (reflection API), which will be retrieved and returned from every object the function is applied to.
Functions.MapEntryKeyProjection<E extends Map.Entry<K,?>,K>	A function that retrieves the key portion of a Map.Entry
Functions.MapEntryValueProjection<E extends Map.Entry<?,V>,V>	A function that retrieves the value portion of a Map.Entry
Functions.MethodProjection<E,F>	A Function which accepts a Method and arguments to provide to the method, which will execute the method on each object it receives as an argument, returning the result.
Iters	A class declaring useful methods for working with Iterator and Iterable objects
Objects	Defines a some simple utility methods for Objects
Ordering<E>	This class provides functionality on top of comparators, such as sorting, searching and range matching.
Rehashers	A collection of default implementations of Rehasher
