RC++Reference-class: General classes for a reference to a C++ object

In omegahat/RAutoGenRunTime: Run-time support for automated interfaces to R

General classes for a reference to a C++ object

Description

The class RC++Reference is the class that holds the address of a C++ object. With the programmatically constructed code (or manually) we can then invoke its C++ methods and access its public fields from within R and generally manipulate the C++ object.

The class RC++ReferenceUseName class is a simple extension of RC++Reference which exploits the fact that the R functions corresponding to the C++ methods for an instance are of the form class_<method name>, e.g. MyClass_plot for a reference class named MyClassPtr.

Objects from the Class

Objects can be created by calls of the form new("RC++Reference", ...). They are usuall returned from calls to R functions that call C++ code to create the object.

Slots

ref:

Object of class "externalptr" this is the R object that holds the address of the C++ object.

classes:

Object of class "character" the name of R classes that correspond to the C++ class hierarchy.
