Interface Summary

Interface	Description
AnonymousTransitionFactory<K,T>	A TransitionFactory that is allowed to implement anonymous transitions.
BaseFormTransition<X>	A transition that requires a form to specify arguments This interface is not implemented directly but defines the signature for both FormTransition and ValidatingFormTransition.
CustomFormContent<O>	Interface for BaseFormTransition or TargetLessTransitions that customise the presentation of the form itself.
DefaultingTransitionFactory<K,T>	TransitionProvider that can generate a default transition for a target if no other transition is specified.
DirectTargetlessTransition<X>	An argument-less transition with a fixed operation.
DirectTransition<X>	An argument-less transition that can proceed directly
ExtraContent<O>	Interface for FormTransition or TargetLessTransitions that provide additional content together with the Form
ExtraFormTransition<O>
ExtraTargetLessTransition<O>
FormTransition<X>	A transition that requires a form to specify arguments
IndexTransitionFactory<K,T>	TransitionProvider that can generate a default transition i.e.
IndexTransitionProvider<K,T>	TransitionProvider that can generate a default TargetLessTransition indexing transition e.g..
NavigationProvider<K,T>	Interface for a TransitionFactory that provides additional top/botton content for navigation
PathTransitionProvider<K,T>	A PathTransitionProvider is a TransitionFactory where the target objects are represented as a location path.
ScriptTransitionFactory<K>	Interface for TransitionFactorys that need to add additional CSS and ECMAScript to the html of a transition.
ShowDisabledTransitions<K,T>	An extension interface to allow a TransitionFactory to show disabled actions
TargetLessTransition<X>	A transition that generates a Form to supply all input.
TitleTransitionFactory<K,T>	A TransitionFactory that can customise the title text
TitleTransitionProvider<K,T>	TransitionProvider that can customise the title text
Transition<X>	Transition is like a virtual method call methods are named by the key type, operate on the target type and return a result type.
TransitionFactory<K,T>	A transition factory represents a set of bespoke operations (transitions) on a target type.
TransitionFactoryCreator<P extends TransitionFactory>	Interface for classes that can generate a TransitionFactory.
TransitionFactoryVisitor<R,T,K>	Visitor for different (incompatible) variants of TransitionFactory
TransitionProvider<K,T>	A TransitionProvider is a TransitionFactory where the target objects can be mapped to and from a single String id.
TransitionVisitor<X>	Visitor to actually implement the transition logic.
ValidatingFormTransition<X>	The same as a FormTransition except that the the initial state of the form is validated and errors displayed rather than waiting for the form to be submitted.
ViewPathTransitionProvider<K,T>	A Path Transition Provider that can use the generic view_target pages.
ViewTarget
ViewTransitionFactory<K,T>	A TransitionFactory that can use the generic view_target pages.
ViewTransitionProvider<K,T>	A Transition Provider that can use the generic view_target pages.

Class Summary

Class	Description
AbstractDirectTargetlessTransition<X>	A simple abstract sub-class for DirectTargetlessTransitions This saves a small amount of boiler plate when no other superclass is required.
AbstractDirectTransition<X>	A simple abstract sub-class for DirectTransitions This saves a small amount of boiler plate when no other superclass is required.
AbstractFormTransition<X>	A simple abstract sub-class for FormTransitions This saves a small amount of boiler plate when no other superclass is required.
AbstractTargetLessTransition<X>	A simple abstract sub-class for TargetlessTransitions This saves a small amount of boiler plate when no other superclass is required.
AbstractTransitionVisitor<K,T>
ConfirmTransition<T>	FormTransition that selects a choice of two DirectTransitions as a result of a yes/no question
ForwardTransition<T>	direct transition that returns a nested result
TransitionFactoryFinder	class that encodes the rules for locating a TransitionFactory from its TransitionFactory.getTargetName() tag,
ViewTransitionFormat<K,T>	A Table.Transform that converts objects to a ViewTransition The object can be either the transition target type or an IndexedReference to that type.
ViewTransitionGenerator<X>	An adapter that implements UIGenerator for the target of ViewTransitionFactory This is intended to allow the target to implement UIProvider without adding excessive dependencies to the ViewTransitionFactory.

Package uk.ac.ed.epcc.webapp.forms.transition Description

classes and interfaces that define transitions. Transitions are a framework for defining form based logic on target types. Transitions use standard jsp and servlets so new transition logic can be added entirely in java. This is the preferred route to add form based logic to an application.
