Group

Group

The
Group
anchor binds a sequence of anchors and actions together.
Properties of the
Group
apply to all child components. Use a
Group
to define operations for the Script to perform on a set of anchors or to control the phase of the nested anchors.
The following table describes the properties of the
Group
anchor:
Property
Description
absent
Defines the behavior of the
Group
anchor when one of its nested, non-optional anchors or actions fails. You can choose one of the following options:
  • Selected.
    Group
    fails.
  • Cleared. Normal behavior.
Use this feature to test for the absence of nested anchors.
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.
marking
Determines whether an anchor is used as the start of the search scope for the succeeding anchor. You can choose one of the following options:
  • begin position. Place a reference point before the current anchor.
  • end position. Place a reference point after the current anchor.
  • full. Place a reference point before and after the current anchor.
  • none. Do not create a reference point.
For more information, see How a Parser Searches for Anchors.
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.
no_initial_phase
Determines whether the Script searches for nested anchors in the main phase. You can choose one of the following options:
  • Cleared. Search for nested anchors according to their individual properties.
  • Selected. Search for nested anchors in the main phase.
Default is cleared.
notifications
A list of
NotificationHandler
components that handle notifications from nested components. For more information, see Notifications.
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.
on_partial_match
Determines the behavior when
Group
does not find all its nested, non-optional anchors. You can choose one of the following options:
  • fail.
    Group
    fails. Default.
  • skip.
    Group
    removes the area spanned by the successful nested anchors from its search scope and tries to find all the nested anchors again. It repeats this process until it finds the anchors or fails.
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.
phase
Determines when the Script processes the component. You can choose one of the following options:
  • initial. The Script processes the component during the initial phase.
  • main. The Script processes the component during the main phase.
  • final. The Script processes the component during the final phase.
For more information, see How a Parser Searches for Anchors.
Default is main.
remark
A user-defined comment that describes the purpose or action of the component.
search_order
Defines the direction of processing nested anchors. You can choose one of the following options:
  • top-down. The nested anchors are processed in the sequence that is defined in the Script.
  • bottom-up. The nested anchors are processed in reverse order. Use this option when data from a later anchor affects the processing of an earlier anchor.
source
Defines a sequence of data holders for input to the
Group
. Each data holder is identified by one of the following properties:
  • Locator. Identifies a single-occurrence or a multiple-occurrence data holder. For multiple-occurrence data holders, each iteration accesses a new occurrence.
  • LocatorByKey. Identifies a multiple-occurrence data holder by key.
  • LocatorByOccurence. Identifies a multiple-occurrence data holder by sequence number.
Use the
source
property when the
Group
is called by another component. For more information, see Source Property.
target
Defines a sequence of data holders for output from the
Group
. If a data holder does not yet exist, it is created. Each data holder is identified by one of the following properties:
  • Locator. Identifies a single-occurrence or a multiple-occurrence data holder. For multiple-occurrence data holders, each iteration creates a new occurrence.
  • LocatorByKey. Identifies a multiple-occurrence data holder by key.
  • LocatorByOccurence. Identifies a multiple-occurrence data holder by sequence number.
Use the
target
property when the output of the
Group
is used by another component. For more information, see Target Property.
