CalculateValue

CalculateValue

Calculates numerical values or concatenates string values.
To calculate numeric values, use the following operators between parameters:
  • +
  • -
  • *
  • /
You can use parentheses to clarify the numeric expression. You can use variables of the following data types:
  • xs:anyType
  • xs:anySimpleType
  • numeric data types
  • string data types
If the parameters are all numeric data types or numeric strings, CalculateValue performs an arithmetic calculation. Non-integer results are rounded to 14 decimal places.
To concatenate strings, use the plus sign (+) operator between parameters and strings.
The following table describes the properties of the
CalculateValue
action:
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.
expression
Defines a JavaScript expression. To represent an input parameter, use a dollar sign ($) followed by an integer. To represent a string, enclose it in single quote marks.
failure_action
Determines the behavior in the event of failure. You can choose one of the following options:
  • Ignore. The transformation continues.
  • HaltExecution. The transformation stops.
Default is Ignore.
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.
params
Defines a list of data holders that contain the input parameters.
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.
result
Determines a data holder that stores the output.
For more information about the JavaScript syntax that the Data Processor transformation supports, see EnsureCondition. For more information about the precision of
xs:decimal
and
xs:float
values, see Precision of Numerical Data.
