On Payoffs

Key On Payoffs in Simulation Node refers to the text labels associated with all possible payoff functions (i.e. functions mapping several real numbers to a boolean represented as objects of type Real To Real Function) designed to be activated only when a trigger event occurs represented as a 1D-array of texts.
The association between each text label and the corresponding payoff function is achieved by finding the unique Contingent Claim object of which the ID specified through its key Claim ID matches the text label here.
Then the found Contingent Claim object contains the sought after payoff function defined through its key On Pmt Fn
If the simulation relates to a Payoff Policy, the labels here will be a subset of those in the first column of the table Time Plan of that Payoff Policy
The reason of them being a "subset" rather than being identical with the mentioned labels is that a few Contingent Claim objects in that table may have no associated payoff function.
At any case, the order of the applicable IDs found in the first column of that table will be retained in the array reported here.
