Package	Description
io.permazen	Abstraction layer allowing access to a Database using normal Java objects.

Class	Description
AbstractIterationSet<E>	Support superclass for Set implementations based on database entries.
AbstractNavigableMap<K,V>	Support superclass for NavigableMap implementations based on database entries.
AbstractNavigableSet<E>	Support superclass for NavigableSet implementations based on database entries.
AbstractXMLStreaming	Support superclass for classes that serialize and deserialize via XML.
ApplicationClassLoader	An URLClassLoader whose classpath can be modified at runtime.
Bounds<T>	Utility class used by AbstractNavigableSet and AbstractNavigableMap to define the (optional) upper and lower bounds of a restricted range.
BoundType	Upper and lower bound types.
ByteReader	Reads bytes from a buffer.
ByteUtil	Byte manipulation utilities.
ByteWriter	Writes bytes to a buffer.
CloseableIterator<E>	An Iterator that is Closeable and can be close()'d without throwing any exceptions.
CloseableRefs<C extends Closeable>	Holds a count of references to a Closeable resource and only close()'s it when the reference count reaches zero.
CloseableTracker	Keeps track of Closeable objects (termed items) that must be reliably closed prior to shutting down some associated context, but that also must not be closed prior to becoming unreachable, when the straightforward strategy of just storing them until context shutdown would require too much memory.
ConvertedList<E,W>	Provides a transformed view of a wrapped List using a strictly invertable Converter.
ConvertedNavigableMap<K,V,WK,WV>	Provides a transformed view of a wrapped NavigableMap using a strictly invertible Converter.
ConvertedNavigableSet<E,W>	Provides a transformed view of a wrapped NavigableSet using a strictly invertable Converter.
ConvertedSet<E,W>	Provides a transformed view of a wrapped Set using a strictly invertable Converter.
ConvertedSpliterator<E,W>	Provides a transformed view of a wrapped ConvertedSpliterator using a strictly invertable Converter.
DiffGenerating<T>	Implemented by classes that can generate a set of differences between themselves and other instances.
Diffs	Used to report difference(s) between two hierarchical structures.
ImmutableNavigableMap<K,V>	An immutable NavigableMap implementation optimized for read efficiency.
ImmutableNavigableSet<E>	An immutable NavigableSet implementation optimized for read efficiency.
LongEncoder	Encodes long values to/from binary, preserving sort order, and such that the length of the encoding is optimized for values near zero.
MovingAverage	Exponential moving average calculator.
NaturalSortAware	Implemented by Comparator classes that know whether or not their ordering is idential to natural ordering.
NavigableSetPager<E>	Allows efficient forward and backward paging through a NavigableSet.
NavigableSets	Utility methods relating to NavigableSet.
ParseContext	Utility class supporting parsing of strings.
ParseException	Exception for parse errors associated with a ParseContext.
Streams	Stream utility methods.
UniqueIterator<E>	CloseableIterator implementation that provides a read-only view of an inner Iterator in which consecutive duplicate values are eliminated.
UnsignedIntEncoder	Encodes unsigned (i.e., non-negative) int values to/from self-delimited binary, preserving sort order, and such that the length of the encoding is optimized for values near zero and encoded values never begin with 0xff.
