public abstract class Flow extends Object
Flow is the runtime representation of a Faces Flow. Once placed into service by the runtime, an instance of this class is immutable. The implementation must be thread-safe because instances will be shared across all usages of the flow within the application.

abstract Map<String,FlowCallNode> |
getFlowCalls()
Return an immutable data structure containing all the flow call nodes declared for this flow. |
abstract String |
getId()
Return the immutable id for this Flow. |
abstract Map<String,Parameter> |
getInboundParameters()
Return an immutable data structure containing the inbound parameters that have been declared for this flow. |
abstract MethodExpression |
getInitializer()
Return the |
abstract List<MethodCallNode> |
getMethodCalls()
Return an immutable data structure containing all the method call nodes declared for this flow. |
abstract Map<String,Set<NavigationCase>> |
getNavigationCases() |
abstract FlowNode |
getNode(String nodeId) |
abstract Map<String,ReturnNode> |
getReturns()
Return an immutable data structure containing all of the return nodes declared for this flow. |
abstract String |
getStartNodeId()
Return the immutable id for the default node that should be activated when this flow is entered. |
abstract Map<String,SwitchNode> |
getSwitches()
Return an immutable data structure containing all of the switch nodes declared for this flow. |
abstract List<ViewNode> |
getViews()
Return an immutable data structure containing all of the view nodes declared for this flow. |
public abstract String getId()
Return the immutable id for this Flow. This must be unique within the defining document (such as an Application Configuration Resources file), but need not be unique within the entire application.
public abstract String getDefiningDocumentId()
Return the immutable application unique identifier for the document in which the argument flow is defined.
public abstract String getStartNodeId()
Return the immutable id for the default node that should be activated when this flow is entered.
public abstract MethodExpression getFinalizer()
Return the MethodExpression
that must be called by the runtime as the last thing that happens
before exiting this flow. Any FlowScoped
beans declared
for this flow must remain in scope until after control returns
from the method referenced by this MethodExpression
.
public abstract MethodExpression getInitializer()
Return the MethodExpression
that must be called by the runtime immediately after activating
any FlowScoped
beans declared for this flow.
public abstract Map<String,Parameter> getInboundParameters()
Return an immutable data structure
containing the inbound parameters that have been declared for
this flow. See FlowHandler.transition(javax.faces.context.FacesContext, javax.faces.flow.Flow, javax.faces.flow.Flow, javax.faces.flow.FlowCallNode, java.lang.String)
for the
specification of how these parameters are used. Inbound
parameters are associated with a specific flow instance, while
outbound parameters are associated with a FlowCallNode
that causes the transition to a new flow.
public abstract List<ViewNode> getViews()
Return an immutable data structure containing all of the view nodes declared for this flow.
public abstract Map<String,ReturnNode> getReturns()
Return an immutable data structure containing all of the return nodes declared for this flow.
public abstract Map<String,SwitchNode> getSwitches()
Return an immutable data structure containing all of the switch nodes declared for this flow.
public abstract Map<String,FlowCallNode> getFlowCalls()
Return an immutable data structure containing all the flow call nodes declared for this flow.
public abstract FlowCallNode getFlowCall(Flow targetFlow)
Return the FlowCallNode
that
represents calling the targetFlow
from this flow, or
null
if targetFlow
cannot be reached from this
flow.
public abstract List<MethodCallNode> getMethodCalls()
Return an immutable data structure containing all the method call nodes declared for this flow.
public abstract Map<String,Set<NavigationCase>> getNavigationCases()
public abstract String getClientWindowFlowId(ClientWindow curWindow)
Obtain the current ClientWindow
from the ExternalContext
. Get the window's id and
append "_" and the return from getId()
. Return the result.
