Mapping functions

Flow variables can be defined and manipulated through flow library, flowlib, functions.

The flowlib custom function library provides several mapping functions for handling flow variables defined for a flow.

Custom flow variables can be set and manipulated with the flowlib mapping functions in the map rules, from a map node in the flow. The values of special flow variables can be viewed, but they cannot be manipulated with these mapping functions.

The mapping functions for manipulating flow variables are:
Note: For details about these functions see the Flow functions documentation.

The GETVARIABLE function retrieves the value of a special variable, if set. All other functions ignore the call on a special variable and return empty to map.
