org.springframework.webflow.engine .TransitionableState

org.springframework.webflow.engine .ViewState

ViewState
public class ViewState extends TransitionableState (Code)
	A view state is a state that issues a response to the user, for example, for soliciting form input. To accomplish this, a `ViewState` makes a ViewSelection , which contains the necessary information to issue a suitable response. See Also: org.springframework.webflow.engine.ViewSelector author: Keith Donald author: Erwin Vervaet

Constructor Summary
public	ViewState(Flow flow, String id) Create a new view state. Parameters: flow - the owning flow Parameters: id - the state identifier (must be unique to the flow) throws: IllegalArgumentException - when this state cannot be added to givenflow, e.g.

Method Summary
protected void	appendToString(ToStringCreator creator)
protected ViewSelection	doEnter(RequestControlContext context) Specialization of State's `doEnter` template method that executes behavior specific to this state type in polymorphic fashion. Returns a view selection indicating a response to issue.
public ActionList	getRenderActionList() Returns the list of actions executable by this view state on entry and on refresh.
public ViewSelector	getViewSelector() Returns the strategy used to select the view to render in this view state.
public ViewSelection	refresh(RequestContext context) Request that the current view selection be reconstituted to support reissuing the response.
public void	setViewSelector(ViewSelector viewSelector) Sets the strategy used to select the view to render in this view state.

Constructor Detail

ViewState
public ViewState(Flow flow, String id) throws IllegalArgumentException(Code)
	Create a new view state. Parameters: flow - the owning flow Parameters: id - the state identifier (must be unique to the flow) throws: IllegalArgumentException - when this state cannot be added to givenflow, e.g. because the id is not unique

Method Detail

appendToString
protected void appendToString(ToStringCreator creator)(Code)

doEnter
protected ViewSelection doEnter(RequestControlContext context) throws FlowExecutionException(Code)
	Specialization of State's `doEnter` template method that executes behavior specific to this state type in polymorphic fashion. Returns a view selection indicating a response to issue. The view selection typically contains all the data necessary to issue the response. Parameters: context - the control context for the currently executing flow, usedby this state to manipulate the flow execution a view selection serving as a response instruction throws: FlowExecutionException - if an exception occurs in this state

getRenderActionList
public ActionList getRenderActionList()(Code)
	Returns the list of actions executable by this view state on entry and on refresh. The returned list is mutable. the state action list

getViewSelector
public ViewSelector getViewSelector()(Code)
	Returns the strategy used to select the view to render in this view state.

refresh
public ViewSelection refresh(RequestContext context) throws FlowExecutionException(Code)
	Request that the current view selection be reconstituted to support reissuing the response. This is an idempotent operation that may be safely called any number of times on a paused execution, used primarily to support a flow execution redirect. Parameters: context - the request context the view selection throws: FlowExecutionException - if an exception occurs in this state

setViewSelector
public void setViewSelector(ViewSelector viewSelector)(Code)
	Sets the strategy used to select the view to render in this view state.
