Method Detail

• getNavigationCase

  public abstract NavigationCase getNavigationCase(FacesContext context,
                                                   String fromAction,
                                                   String outcome)

  Return the NavigationCase representing the navigation that would be taken had NavigationHandler.handleNavigation(javax.faces.context.FacesContext, java.lang.String, java.lang.String) been called with the same arguments or null if there is no such case.

  Parameters:

  context - The FacesContext for the current request

  fromAction - The action binding expression that was evaluated to retrieve the specified outcome, or null if the outcome was acquired by some other means

  outcome - The logical outcome returned by a previous invoked application action (which may be null)

  Throws:

  NullPointerException - if context is null

• getNavigationCase

  public NavigationCase getNavigationCase(FacesContext context,
                                          String fromAction,
                                          String outcome,
                                          String toFlowDocumentId)

  Return the NavigationCase representing the navigation that would be taken had NavigationHandler.handleNavigation(javax.faces.context.FacesContext, java.lang.String, java.lang.String) been called with the same arguments or null if there is no such case. Implementations that comply the version of the specification in which this method was introduced must override this method. For compatibility with decorated implementations that comply with an earlier version of the specification, an implementation is provided that simply calls through to getNavigationCase(javax.faces.context.FacesContext, java.lang.String, java.lang.String), ignoring the toFlowDocumentId parameter.

  Parameters:

  context - The FacesContext for the current request

  fromAction - The action binding expression that was evaluated to retrieve the specified outcome, or null if the outcome was acquired by some other means

  outcome - The logical outcome returned by a previous invoked application action (which may be null)

  toFlowDocumentId - The value of the toFlowDocumentId property for the navigation case (which may be null)

  Throws:

  NullPointerException - if context is null

• getNavigationCases

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

  Return a Map<String, Set<NavigationCase>> where the keys are <from-view-id> values and the values are Set<NavigationCase> where each element in the Set is a NavigationCase that applies to that <from-view-id>. The implementation must support live modifications to this Map.

  Since:

  2.0

• performNavigation

  public void performNavigation(String outcome)

  A convenience method to signal the JavaServer Faces implementation to perform navigation with the provided outcome. When the NavigationHandler is invoked, the current viewId is treated as the "from viewId" and the "from action" is null.

  Throws:

  IllegalStateException - if this method is called after this instance has been released

• inspectFlow

  public void inspectFlow(FacesContext context,
                          Flow flow)

  Called by the flow system to cause the flow to be inspected for navigation rules. For backward compatibility with earlier implementations, an empty method is provided.
