ProxyFunction-class {XR}

A Class for Proxy Functions

Description

A class for functions in R that call functions in a server language. The arguments in a call are converted to equivalent server language objects, via asServerObject(). These usually include proxy objects in R for results previously computed through the same interface evaluator.

Details

This class is always subclassed for a particular server language. Proxy functions for that language will use a corresponding evaluator to find metadata about the server function.
