AlternativeMappings

AlternativeMappings

The
AlternativeMappings
Mapper anchor defines a set of alternative Mapper anchors. Define a criterion for selecting one alternative. Only the accepted alternative affects the output.
The following table describes the properties of the
AlternativeMappings
Mapper anchor:
Property
Description
disabled
Determines whether the Script ignores the component and all of the child components. Use this property to test, debug, and modify a Script. You can choose one of the following options:
  • Selected. The Script ignores the component.
  • Cleared. The Script applies the component.
The default is cleared.
name
A descriptive label for the component. This label appears in the log file and the
Events
view. Use the
name
property to identify the component that caused the event.
on_fail
The action to take if the component fails. You can choose one of the following options:
  • Cleared. Take no action.
  • CustomLog. Write to the user log.
  • LogError. Write an error message to the engine log.
  • LogInfo. Write an information message to the engine log.
  • LogWarning. Write a warning message to the engine log.
  • NotifyFailure. Send a notification.
Default is cleared. For more information about handling component failures, see Failure Handling.
optional
Determines whether a component failure causes the parent component to fail. You can choose one of the following options:
  • Selected. Component failure does not cause the parent component to fail.
  • Cleared. Component failure causes the parent component to fail.
Default is cleared. For more information about component failure, see Failure Handling.
remark
A user-defined comment that describes the purpose or action of the component.
selector
Determines the criterion for selecting one alternative Mapper. You can choose one of the following options:
  • ScriptOrder. The Script tests the nested Mapper anchors in the sequence that they are defined in the Script. It accepts the first one that succeeds. If all the nested Mapper anchors fail, the
    AlternativeMappings
    component fails.
  • NameSwitch. The Script searches for the nested Mapper anchor whose
    name
    property is specified in a data holder. It ignores the other nested Mapper anchors. If the named Mapper anchor fails, the
    AlternativeMappings
    component fails.
Default is ScriptOrder.
