class DefineFunction extends Function with HasOpType with HasDataType with PmmlElement
Defines new (user-defined) functions as variations or compositions of existing functions or transformations. The function's name must be unique and must not conflict with other function names, either defined by PMML or other user-defined functions. The EXPRESSION in the content of DefineFunction is the function body that actually defines the meaning of the new function. The function body must not refer to fields other than the parameter fields.
