Interface Summary

Interface	Description
CheckedCollection<E>	Collection that ensures that all elements are assignable to a given base type.
Converter	Converts values of one type into another.
ConverterFactory	Factory used to create instances of Converter.
ObjectCache	A cache for arbitrary objects.
SoftValueHashMap.ValueCleaner	A delegate that can be used to perform clean up operation, such as resource closing, before the values cached in soft part of the cache gets disposed of

Class Summary

Class	Description
AbstractInternationalString	A string that has been internationalized into several locales.
Arguments	A helper class for parsing command-line arguments.
CanonicalSet<E>	A canonical set of objects, used to optimize memory use.
CharUtilities	A set of utilities for characters handling.
CheckedArrayList<E>	A checked and synchronized List.
CheckedHashMap<K,V>	A checked and synchronized Map.
CheckedHashSet<E>	A checked and synchronized Set.
ClassChanger<S extends Comparable<S>,T extends Number>	A central place to register transformations between an arbitrary class and a Number.
Classes	A set of miscellaneous methods working on Class objects.

DerivedSet<B,E>	A set whose values are derived from an other set.
DisjointSet<E>	A set which is disjoint from others DisjointSets.
EchoWriter	A writer that copy all output to an other stream.
ExpandedTabWriter	Writes characters to a stream while expanding tabs ('\t') into spaces.
FrequencySortedSet<E>	A set with elements ordered by the amount of time they were added.
GenericName	Base class for generic scoped and local name structure for type and attribute name in the context of name spaces.
GeoToolsUnitFormat	Base class extending UOM SimpleUnitFormat that provides the same setup as SimpleUnitFormat.getInstance() but allows for extension and can, unlike the libraries we depend on, actually parse back what it formatted (might be reworked/removed once this ticket is solved, https://github.com/unitsofmeasurement/uom-se/issues/201, but will require an overhaul of our unit dependencies to a new set of jars).
GeoToolsUnitFormat.BaseGT2Format	Base class that just copies UnitFormat default instance contents

GrowableInternationalString	An implementation of international string using a map of strings for different locales.
IndentedLineWriter	A writer that put some spaces in front of every lines.
IndexedResourceBundle	ResourceBundle implementation using integers instead of strings for resource keys.
IndexedResourceCompiler	Resource compiler.
IntegerList	A list of unsigned integer values.
Java6	Temporary methods to be removed when we will be allowed to compile for Java 6.
JDBC	A set of utilities methods related to JDBC (Java Database Connectivity).
KeySortedList<K extends Comparable<K>,V>	List of elements sorted by a key which is not the element itself.
KVP	A linked HashMap set up for easy construction.
LazySet<E>	An immutable set built from an iterator, which will be filled only when needed.
LineFormat	Parses a line of text data.
LineWriter	Writes characters to a stream while replacing various EOL by a unique string.
LocalName	Identifier within a name space for a local object.
LRULinkedHashMap<K,V>	A Map with a fixed maximum size which removes the least recently used (LRU) entry if an entry is added when full.
MapEntry<K,V>	A default implementation of Map.Entry which map an arbitrary key-value pairs.
MeasurementRange<T extends Number & Comparable<? super T>>	A range of numbers associated with a unit of measurement.
MemberNameImpl	The name to identify a member of a record.
NameFactory	A factory for GenericName objects.
NIOUtilities	Utility class for managing memory mapped buffers.
NullEntityResolver	NullObject implementation for EntityResolver2 (used as an alternative to null checks).
NumberedLineWriter	A writer that put line number in front of every line.
NumberRange<T extends Number & Comparable<? super T>>	A range of numbers.
ObjectCaches	This is facade around several constructs used by GeoTools for internal caching.
OptionalDependencies	Bridges to optional dependencies (especially widget-swing module).
PartiallyOrderedSet<E>	Set of elements having a partial order, established by setting before/after relationship calling PartiallyOrderedSet.setOrder(Object, Object)
PreventLocalEntityResolver	EntityResolver implementation to prevent use external entity resolution to local files.
Range<T extends Comparable<? super T>>	A range between a minimum and maximum comparable.
RangeSet<T extends Comparable<? super T>>	An ordered set of ranges.
Ranks	Sorts elements in an array while remembering their ranks.

ScopedName	Fully qualified identifier for an object.
SimpleInternationalString	A simple international string consisting of a single string for all locales.
SoftValueHashMap<K,V>	A hash map implementation that uses soft references, leaving memory when an entry is not used anymore and memory is low.
SwingUtilities	A collection of utility methods for Swing.
TableWriter	A character stream that can be used to format tables.
UnmodifiableArrayList<E>	An unmodifiable view of an array.
URLs	Utilities for manipulating and converting to and from URLs.
Utilities	Miscellaneous methods, including cnvenience methods for equals and hashCode implementations.
Version	Holds a version number.
WeakCollectionCleaner	A thread invoking Reference.clear() on each enqueded reference.
WeakHashSet<E>	A set of objects hold by weak references.
WeakValueHashMap<K,V>	A hashtable-based Map implementation with weak values.
X364	Escape codes from ANSI X3.64 standard (aka ECMA-48 and ISO/IEC 6429).
XArray	Simple operations on arrays.
XMath	Simple mathematical functions.

Exception Summary

Exception	Description
ContentFormatException	Throws when a stream can't be parsed because some content uses an invalid format.
UnsupportedImplementationException	Throws when an operation can't use arbitrary implementation of an interface, and a given instance doesn't meet the requirement.

Annotation Types Summary

Annotation Type	Description
SuppressFBWarnings	GeoTools custom ersion of Spotbugs SuppressFBWarnings, added here to avoid dependencies on extra jars and for IDE friendlyness (IntelliJ does not seem to provide completion for optional dependencies, even if annotations not found at runtime apparently don't cause issues).

Package org.geotools.util Description

Contains utilities and addition to the collection framework. Some classes implements the Set interface and provides facilities for mutually exclusive set, caching or handling ranges of values.
