Class Summary

Class	Description
Aggregation	Performs and holds the results of a variety of aggregate calculations.
Aggregator	Transforms a set of objects into an Aggregate object, generated by iterating across the set.
AlphabeticComparator	Compares alphabetically.
AndCondition	A boolean AND predicate - it takes a list of ANDed subConditions.
ArrayIterator	An enumeration that traverses an array of objects.
ArrayListRecord	This is a Record whose values are maintained in an internal ArrayList.
BeanGraph	This class treats an object as the root node in a graph.
BeanGraphNode	A node in a bean graph traversal.
BeanRecord	This is a wrapper class that takes an arbitrary object and determines the editable properties from it using the JavaBeans introspector.
ClassGenealogyIterator	An enumeration of all superclasses and all interfaces, superinterfaces, etc.
ClassMappedFactory	A Factory whose parts are mapped to classes as in ClassMapping.
ClassMapping	A ClassMapping is an association between classes and objects.
ConditionalTransform	An ObjectTransform which can execute one of two subtransforms based on a condition.
CountingBag	A container which can hold multiple copies of objects.
DataUtilities	This is a utility class, with methods that do various handy data mangling..
DictionaryValueTransform	Applies a subtransform to every value in a Map object.
DovetailMultiIterator	An enumeration that traverses an ordered set of sub-enumerations in breadthwise, round-robin manner.
EmptyIterator	An enumeration with nothing in it.
EnumeratedType	An enumerated type; i.e., one that has a limited set of discrete values.
Factory	A factory creates an object of a specific class upon request.
FactoryMethodFactory	A Factory which returns parts based on calls to factory methods on itself.
FieldCriterion	A criterion for looking up an record based on the values of some of its fields.
FieldDef	Field definition for a Record.
FieldIndex	An index for looking up a record based on the values of some of its fields.
FieldTranslator	This is a TranslatingMap whose sole purpose is the translation of a field set (the output of fields()) for one type of Record to the corresponding field set for another type.
FilterIterator	An enumeration that filters another enumeration by some criteria.
FilterTransform	Transforms a collection of objects into another collection based on a selection criterion.
FlattenedBean	This class uses BeanRecord to expose the properties of a provided object.
GroupByPropertyValue	Transforms a collection of objects into a Map that groups objects together based on shared values for a specified property.
HashRecord	This was a Record whose values were maintained in an internal HashMap (but now are maintained in a Naming so they're case-insensitive).
IfThenTransform	A kind of weird transform - if the original (or property, if "property" is specified) .equals() the ifCondition, then returns the thenResult property, otherwise returns the elseResult property.
IntrospectionLib	A library of introspection convenience functions.
IntrospectionProfile	This is a class which builds and holds various items of interest for introspectors.
LeaveAloneToken	A token object that indicates that a field should be left in its current state.
LookupDatabase	This is a sort of object database.
LookupReference	A reference to an item in a LookupDatabase.
LookupRegistry	A global registry for lookup databases.
MagicCookie	From the Hacker's Map/Jargon file: magic cookie [UNIX] n.
MappedTransform	A transform that uses a Map to translate between the domain and range.
MetaBean	A MetaBean; this is a description of a bean and its properties that don't require the class to exist (handy for beating on TOFs and such) Just for confusion it's also a bean itself.
MetaClass	A MetaClass; this is just a beanified classname, really.
MetaImport	A MetaImport; this is just a beanified storage path, really.
MetaTextImport	A MetaImport; this is just a beanified storage path, really.
MultiTransform	Applies a list of subtransforms to the given object.
NameComparator	A comparator for strings that cares not what stupid case you have.
NameMap	A TreeMap whose keys are strings and that is case-insensitive.
NotCondition	A boolean NOT predicate.
NumericPrefixComparer	Compares objects first by any numeric prefix, then alphabetically.
OptionalTransform	A transform that is performed conditionally - if the condition fails the original object is returned.
OrCondition	A boolean OR predicate - it takes a list of ORed subConditions.
ParallelMultiTransform	Applies a set of named subtransforms to the given object.
Picklist	An enumerated list of objects, generally used for validation, choice boxes, etc.
PicklistItem	An item on a picklist.
PicklistManager	Manages and doles out picklists on request.
PropertyComparer	Compares objects using a list of properties - sorts by each property in turn, using (by default) a NumericPrefixComparer.
PropertyMatch	A UnaryPredicate that returns true if the given BeanGraph properties for the object match the given values.
PropertyScrambler	Lets you rename and duplicate BeanGraph properties.
PropertySettingMangler	Sets properties in a BeanGraphable object using a map of values.
PropertyTransformingMangler	Transforms a subproperty of an BeanGraphable object.
ReferenceCookie	This is a cookie that contains another object.
ReferenceList	A mapping of a long refID to an Object, used to save and load pointer references.
ReferenceMap	A mapping of an object to an int ID, used to build goedels for pointer references.
ResultSetIterator	Puts an Iterator wrapper around a ResultSet.
ResultSetMap	Puts a Map wrapper around a ResultSet.
RoundRobinIterator	Loops around a vector in round-robin fashion.

SingleIterator	An iteration of a single object.
SinglePropertyIndex	A LookupIndex that indexes according to the value of a single property a la BeanGraph.
ToStringIndex	A LookupIndex that indexes according to the output of toString().
TransformAndSetPropertyMangler	Transforms a BeanGraphable object and sets the result as a subproperty of the original.
TranslatingMap	A dictionary that serves as a translator between a source dictionary and a client.
TreeNode	This is a node of a homogenous tree data structure.
