Jaggregate version 3.2.1

Changes in release 3.2.1

• Added class Throwables.
• Restructured some internals.
• Maven-ized project's build.

Changes in release 3.2

• Fixed a bug with SortedCollections produced by the zero-argument Collection.toSortedCollection(). Such collections could not be serialized, because the Comparator they use was not itself Serializable. This has been remedied.
• Added *From and *With methods to Dictionary and IdentityDictionary, compiler warnings about generic array creation be damned.

Changes in release 3.1.1

• Fixed a bug with NaturallySortedCollections. In order to serialize SortedCollections, the Comparators they use should themselves be Serializable. However, the internal Comparator which NaturallySortedCollections use was not Serializable. This has been remedied.

Changes in release 3.1

• Added class Iterables, which enables Jaggregate Collection-like functionality for Iterable structures.
• Un-published the Javadoc for the jaggregate.number classes which support Interval. The classes are public but are not intended to be used directly; hence, we have rescinded our decision to publish the class Javadocs for that package.

Changes in release 3.0

• Added several static factory methods to the concrete collection classes, to leverage generic type inference.
• Added class Interval and its supporting structures. Intervals are read-only arithmetic progressions of numbers.
• Added class Arrays for manipulating arrays.
• Added Collections.toDictionary( UnaryFunction ) and Collections.toIdentityDictionary( UnaryFunction ).
• Removed deprecated method Objects.nullSafeToString().

Changes in release 2.0

• Changed Collection.removeAll( E... ) and Collection.retainAll( E... ) to have the parameter list ( E[] ), and added overloads with parameter list ( E, E... ). This prevents a caller from specifying zero arguments to the varargs overloads of these methods. It would look kind of funny to call removeAll() with no arguments and not have anything removed, or retainAll() and have everything removed. If you really mean to have this behavior, you can still call the ( E[] ) overload with a zero-length array.
• Changed AbstractDictionary.removeAllKeys( K... ) and AbstractDictionary.retainAllKeys( K... ) to have the parameter list ( K[] ), and added overloads with parameter list ( K, K... ). This prevents a caller from specifying zero arguments to the varargs overloads of these methods. It would look kind of funny to call removeAllKeys() with no arguments and not have anything removed, or retainAllKeys() and have everything removed. If you really mean to have this behavior, you can still call the ( K[] ) overload with a zero-length array.
• Unary and binary functors and predicates now are abstract classes instead of interfaces, to hold common implementations of new operations.
• Predicates now have methods and(), or(), not(), and xor(), to allow logical combinations of predicates.
• Eliminated unused type parameter S extends ReadOnlySequence from the declaration of PuttableStream.
• Binary predicates and functors now have methods bindFirst() and bindSecond(), to allow creation of unary predicates and functors from binary ones.
• Unary functors now have a compose() method, to allow the functional composition of two functors.
• Common predicates on objects in general: equalTo(), isA(), sameAs().
• Deprecated Objects.nullSafeToString().
• Common predicates and functors on Comparables: between(), lessThan(), greaterThan(), max(), min(), and so forth.
• Common predicates and functors on Strings: startsWith(), indexOf(), and so forth.
• A JUnit assertion method that uses predicates. See this blog entry for the inspiration behind this capability. To support this assertion method, unary predicates can describe() themselves; binary predicates provide information to help unary predicates created from bindFirst() and bindSecond() describe() themselves also.
• Javadoc cleanup here and there.
• Suppressed "unchecked"-flavor compiler warnings within Jaggregate source where it was deemed safe to do so.

Release 1.0

• First major release.
• Includes concrete classes Bag, IdentityBag, Set, IdentitySet, OrderedCollection, SortedCollection, NaturallySortedCollection, Dictionary, IdentityDictionary, ReadStream, WriteStream, Objects, Strings, Collections, Comparing, Pair, KeyValuePair.
• Includes interfaces for unary and binary functors and predicates, the analogues of one-arg and two-arg Smalltalk blocks.
