Between elements of the same logic
In one and the same logic, say a pricing logic, I can refer to a constant (e.g. parameter name) in previous elements like this:
Assume there is an element Params defined as
Further down in the logic, in another element, those constants are looked up in something like
This works since the static strings defined in the Params element are accessible from subsequent elements in the same logic.
Between elements of different logics
However, if element Params was defined in a Groovy library – not an unusual use case if the parameter names are to be shared across multiple logics – then the above scheme no longer works.
There is, however a way to make it work. Say you define a Groovy library named 'PO'. Within that library you define a Params element, but this time
you define the static parameter names as:
Then you can refer to those parameter names in ordinary logics with
