Package io.permazen.util

General utility classes used with Permazen.

Interface Summary

Interface	Description
CloseableIterator<E>	An Iterator that is Closeable and can be close()'d without throwing any exceptions.
DiffGenerating<T>	Implemented by classes that can generate a set of differences between themselves and other instances.

Class Summary

Class	Description
AbstractIterationSet<E>	Support superclass for Set implementations for which calculating AbstractIterationSet.size() requires an iteration through all of the set's elements to count them.
AbstractNavigableMap<K,V>	Support superclass for NavigableMap implementations.
AbstractNavigableSet<E>	Support superclass for NavigableSet implementations for which calculating size() requires an iteration through all of the set's elements to count them.
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.
ByteReader	Reads bytes from a buffer.
ByteUtil	Byte manipulation utilities.
ByteWriter	Writes bytes to a buffer.
CastFunction<T>	A Function that casts objects to some type.
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.
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.
ImplementationsReader	Scans the classpath and parses XML descriptor files describing implementation classes.
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.
NavigableSetPager<E>	Allows efficient forward and backward paging through a NavigableSet.
NavigableSets	Utility methods relating to NavigableSet.
ParseContext	Utility class supporting parsing of strings.
UniqueIterator<E>	Iterator 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.
