The DataVect and ExprEnv classes are how your plug-in interacts with the calculation engine.

DataVect Public Functions

The DataVect class is a simple vector of Data objects. FileMaker passes a DataVect to your plugin call that holds the arguments supplied to the external function.

ExprEnv Public Functions

The ExprEnv class allows your plugin to interact with the calculation engine, it can evaluate FileMaker expressions and SQL, and there are methods to dynamically register / unregister external functions.
