Detailed Description

Class CXXR::ProvenanceTracker.


Function Documentation

void flagXenogenesis ( )

Flag up xenogenesis.

This function is called to indicate to the provenance tracker that in evaluating the current top-level command, the behaviour of the interpreter has been influenced by something external to it, e.g. by reading an external file, or by accepting user input. Provenance-tracked bindings created by the top-level command subsequently to this call will be flagged as having xenogenous provenance.
