Interface Summary

AuthFilter	An AuthFilter is a plain java class implementing data visibility logic for use by UI nodes and Authorizer nodes.
Authorizer	The Authorizer interface identifies a node as being able to perform the special purpose functions required for secure processing.
AuthUser	An interface to identify a user of the system for authorization purposes.
AuthUserLookup	An interface declaring this object supports finding an AuthUser via their ID.
CommBridge	A bridge between communications used internally by the application, and communications used outside the application.
IDCache	Defines a reliable and efficient lookup of a persistent object instance via its unique identifier.
IDLookup	Provides general object resolution capabilities.
InstanceClassEnumerator	Provide a mapping between short names of messages or interfaces, and derived or implementing classes.
MessageValidator	A MessageValidator class can be configured as part of a TestScript, to check for arbitrary input situations.
NameLookup	Provides general object resolution capabilities.
Resolvable	Interface indicating reference fields within this object can be resolved.
SandEncryptor	Simplified interface for reversable string encryption used in messaging and other applications.
SimpleMailSender	A simple mail send utility interface.
TrustedInstanceLookup	An interface declaring this object supports direct, full retrieval of the current message instance information.
UIFileLocator	Provide file and URL access to uploaded or generated files.
UIFormAdaptor	Renders/reconstructs a UIFormContext to/from a user interface.
UIFormAdaptorCallback	Callback interface for UIFormAdaptor providing IDLookup, NameLookup, and dynamic form processing functions.
UIFormManager	Handles the processing of a UIFormContext.
UIFormOwner	Callback interface implemented by classes that use UIFormManager.
UIRenderInput	An input operand used by a UIFormAdaptor to retrieve input parameters.
UIRenderOperand	A relatively opaque class representing what a UIFormAdaptor needs to enable output rendering or input reconstruction.
UIRenderOutput	A common base for all output operands.
UIRenderOutputDirect	Used by a UIFormAdaptor to render a form for display.
UIRenderOutputStream	Used by a UIFormAdaptor to render a form for display.
UIRenderOutputString	Used by a UIFormAdaptor to render a form for display, where the rendered output can be accessed as a String afterwards.

Class Summary

AbstractFormManager	Provides a root implementation of a UIFormManager delegating data manipulation tasks to extending classes.
ArrayAssociation	A standard associative list represented by two equal length arrays.
ArrayUtils	Simple array management utilities to fill gaps in common use.
ConfirmationValidator	The ConfirmationValidator implements the MessageValidator interface by simply confirming everything is what it looks like.
CSVTransforms	Converts an array of basic types to a comma separated value String.
DateUtil	Common date manipulation utilities.
EnvGrabber	Provides a utility to return the value of something set as an environment variable.
FileUtil	Common file manipulation utilities.
Hexifier	An alternative to base64 encoding in some cases.
IDCacheBase	Provides common methods for all IDCache implementations.
IntReference	Holds a reference to an int.
MatchUtil	Simple match expression evaluation.
NamedSingletonIDCache	Provides singleton instances of one or more IDCaches.
NodeLocalIDCache	A simple IDCache for use by any single node.
NullEncryptor	A degenerate SandEncryptor that simply returns what it was given without doing any work.
PropUtils	A utility for value lookup in localized property files.
ReaderWriterLock	A multiple reader single writer lock utility.
RootedFormManager	An implementation of a UIFormManager used for working with a tree of non-persistent objects.
SampleEncryptor	A sample encryptor implementation.
SingletonIDCache	A singleton IDCache for shared object caching.
StandardFormManager	An implementation of UIFormManager suitable for general use.
StringUtil	Utilities for String value manipulation.
TextEncoder	A utility class for encoding and decoding text, used to preserve text formatting.
UIFormContext	A contract between a user interface and the system.
UserWorkLog	An accumulative logger for messages to be delivered to the user while the system does work.
XMLTextProcessing	Provides raw text translation services for XML.

Exception Summary

DuplicateReferenceException	A specialized exception for reporting duplicate references.
MailException	A specialized exception for mail processing problems.
SandEncryptorException	A specialized exception for UIFormManagers to complain with.
UIFormAdaptorException	A specialized exception for UIFormAdaptors to complain with.
UIFormManagerException	A specialized exception for UIFormManagers to complain with.
