Same Logic

In one and the same logic, say a e.g. pricing logic, I you can refer to a constant (e.g. parameter name) in previous elements like this:

• Assume there is an element Params defined as as:

  Paste code macro
  language groovy title Code of element 'Params'
  PARAM_PE = "PE" PARAM_MARGIN = "Margin"

  
  

• Further down in the logic, in another element, those constants are looked up in something like like this:

  Paste code macro
  language groovy title Referencing constants from another elements
  api.vLookup( Params.PARAM_PE, ...)

  
  

This works since the static strings defined in the Params element are accessible from subsequent elements in the same logic.

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 You define the static parameter names as: 

  Paste code macro
  language groovy title Definition of constants in Groovy Library code
  @Field PARAM_PE = "PE" @Field PARAM_MARGIN = "Margin"

  
  

• Then you can refer to those parameter names in ordinary logics with with:

  Paste code macro
  language groovy title Referencing Groovy Library constants from another other elements
  libs.PO.Params.PARAM_PE
