Property-Map-Value method
|
|
The Property-Map-Value method evaluates a one-dimensional map value
(Rule-Obj-MapValue rule type) defined in the parameter. The
method sets the result as a value for a Single Value
property.
The related method Property-Map-ValuePair works similarly for two-dimensional map values.
In the Diagram tab of a flow rule, a
decision shape (
) can reference
a map value rule.
This method has three parameters:
Parameter |
Description |
| PropertyName |
Identify a target property to hold the result of this method. (You can't use a local variable here.) MAYED 11/3/06 |
| MapName |
Enter the name — second key part — of a map value rule (Rule-Obj-MapValue rule type). |
| RowInput |
Optional. Identify an input value for the row, as a literal
constant or |
| AllowMissingProperties |
Select to cause map value processing to continue even if a
referenced property is not present on the clipboard. For a
Clear to cause map value processing to halt when processing references a property that is not present on the clipboard. This causes the system to store an output parameter MapValueStatus with value "NotFound" on the parameter page of the activity. |
The system forms a map value rule key from the value in the second parameter and the class of the step page or primary page. It uses rule resolution to find the map value rule.
It evaluates this one-dimensional) rule using as input the value you supply in the RowInput parameter (or the property identified the Input tab of the map value rule).
It stores the result in the property you identified in the PropertyName parameter.
This method updates the pxMethodStatus property. See How to test method results using a transition.
