Method Detail

• id

  public abstract FlowBuilder id(String definingDocumentId,
                                 String id)

  Set the defining document id and flow id of this flow.

  Parameters:

  definingDocumentId - The defining document id of this flow, or the empty string if this flow does not need a defining document id.

  id - the id of the flow

  Throws:

  NullPointerException - if any of the parameters are null

• viewNode

  public abstract ViewBuilder viewNode(String viewNodeId,
                                       String vdlDocumentId)

  Define a view node in a flow graph.

  Parameters:

  viewNodeId - Within the flow graph, the id of this view node. Must be unique among all nodes in this flow graph.

  vdlDocumentId - The fully qualified path to the view node within this flow.

  Throws:

  NullPointerException - if any of the parameters are null

  Since:

  2.2

• navigationCase

  public abstract NavigationCaseBuilder navigationCase()

  Define a particular combination of conditions that must match for this case to be executed, and the view id of the component tree that should be selected next.

  Since:

  2.2

• switchNode

  public abstract SwitchBuilder switchNode(String switchNodeId)

  Define a particular list of cases that will be inspected in the order they are defined to determine where to go next in the flow graph. If none of the cases match, the outcome from the default case is chosen.

  Parameters:

  switchNodeId - Within the flow graph, the id of this switch node. Must be unique among all nodes in this flow graph.

  Throws:

  NullPointerException - if any of the parameters are null

  Since:

  2.2

• returnNode

  public abstract ReturnBuilder returnNode(String returnNodeId)

  Define a return node. This node will cause the specified outcome to be returned to the calling flow.

  Parameters:

  returnNodeId - Within the flow graph, the id of this return node. Must be unique among all nodes in this flow graph.

  Throws:

  NullPointerException - if any of the parameters are null

  Since:

  2.2

• methodCallNode

  public abstract MethodCallBuilder methodCallNode(String methodCallNodeId)

  Define a method call node. This node will cause the specified method to be invoked, passing parameters if necessary. The return from the method is used as the outcome for where to go next in the flow. If the method is a void method, the default outcome is used.

  Parameters:

  methodCallNodeId - Within the flow graph, the id of this method call node. Must be unique among all nodes in this flow graph.

  Throws:

  NullPointerException - if any of the parameters are null

  Since:

  2.2

• flowCallNode

  public abstract FlowCallBuilder flowCallNode(String flowCallNodeId)

  Define a flow call node. This node will cause the specified flow to be called, passing parameters if necessary.

  Parameters:

  flowCallNodeId - Within the flow graph, the id of this return node. Must be unique among all nodes in this flow graph.

  Throws:

  NullPointerException - if any of the parameters are null

  Since:

  2.2

• initializer

  public abstract FlowBuilder initializer(MethodExpression methodExpression)

  A MethodExpression that will be invoked when the flow is entered.

  Parameters:

  methodExpression - the expression to invoke, must reference a zero-argument method.

  Throws:

  NullPointerException - if any of the parameters are null

  Since:

  2.2

• initializer

  public abstract FlowBuilder initializer(String methodExpression)

  A MethodExpression that will be invoked when the flow is entered.

  Parameters:

  methodExpression - the expression to invoke, must reference a zero-argument method.

  Throws:

  NullPointerException - if any of the parameters are null

  Since:

  2.2

• finalizer

  public abstract FlowBuilder finalizer(MethodExpression methodExpression)

  A MethodExpression that will be invoked when the flow is exited.

  Parameters:

  methodExpression - the expression to invoke, must reference a zero-argument method.

  Throws:

  NullPointerException - if any of the parameters are null

  Since:

  2.2

• finalizer

  public abstract FlowBuilder finalizer(String methodExpression)

  A MethodExpression that will be invoked when the flow is exited.

  Parameters:

  methodExpression - the expression to invoke, must reference a zero-argument method.

  Throws:

  NullPointerException - if any of the parameters are null

  Since:

  2.2

• inboundParameter

  public abstract FlowBuilder inboundParameter(String name,
                                               ValueExpression expression)

  A parameter that will be populated with the value from a correspondingly named outbound parameter from another flow when this flow is entered from that flow.

  Parameters:

  name - the parameter name

  expression - the ValueExpression to populate with the inbound value when the flow is called.

  Throws:

  NullPointerException - if any of the parameters are null

  Since:

  2.2

• inboundParameter

  public abstract FlowBuilder inboundParameter(String name,
                                               String expression)

  A parameter that will be populated with the value from a correspondingly named outbound parameter from another flow when this flow is entered from that flow.

  Parameters:

  name - the parameter name

  expression - the ValueExpression String to populate with the inbound value when the flow is called.

  Throws:

  NullPointerException - if any of the parameters are null

  Since:

  2.2

• getFlow

  public abstract Flow getFlow()

  Called as the last step in flow definition, this method must perform any implementation specific initialization and return the built Flow. If called more than one time during a given flow building process, the second and subsequent invocations must take no action and return the built flow.

  Throws:

  IllegalStateException - if the id(java.lang.String, java.lang.String) method had not been called prior to this method being called.
