Class Flow

java.lang.Object
javax.faces.flow.Flow
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.

  • Constructor Details

    • Flow

      public Flow()

  • Method Details

    • getId

      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.

      Since:
      2.2

    • getDefiningDocumentId

      public abstract String getDefiningDocumentId()

      Return the immutable application unique identifier for the document in which the argument flow is defined.

      Since:
      2.2

    • getStartNodeId

      public abstract String getStartNodeId()

      Return the immutable id for the default node that should be activated when this flow is entered.

      Since:
      2.2

    • getFinalizer

      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.

      Since:
      2.2

    • getInitializer

      public abstract MethodExpression getInitializer()

      Return the MethodExpression that must be called by the runtime immediately after activating any FlowScoped beans declared for this flow.

      Since:
      2.2

    • getInboundParameters

      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.

      Since:
      2.2

    • getViews

      public abstract List<ViewNode> getViews()

      Return an immutable data structure containing all of the view nodes declared for this flow.

      Since:
      2.2

    • getReturns

      public abstract Map<String,ReturnNode> getReturns()

      Return an immutable data structure containing all of the return nodes declared for this flow.

      Since:
      2.2

    • getSwitches

      public abstract Map<String,SwitchNode> getSwitches()

      Return an immutable data structure containing all of the switch nodes declared for this flow.

      Since:
      2.2

    • getFlowCalls

      public abstract Map<String,FlowCallNode> getFlowCalls()

      Return an immutable data structure containing all the flow call nodes declared for this flow.

      Since:
      2.2

    • getFlowCall

      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.

      Since:
      2.2

    • getMethodCalls

      public abstract List<MethodCallNode> getMethodCalls()

      Return an immutable data structure containing all the method call nodes declared for this flow.

      Since:
      2.2

    • getNode

      public abstract FlowNode getNode(String nodeId)

    • getNavigationCases

      public abstract Map<String,Set<NavigationCase>> getNavigationCases()

    • getClientWindowFlowId

      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.
