# srun.swg #
|
|
#
|
|
# This is the basic code that is needed at run time within R to
|
|
# provide and define the relevant classes. It is included
|
|
# automatically in the generated code by copying the contents of
|
|
# srun.swg into the newly created binding code.
|
|
|
|
|
|
# This could be provided as a separate run-time library but this
|
|
# approach allows the code to to be included directly into the
|
|
# generated bindings and so removes the need to have and install an
|
|
# additional library. We may however end up with multiple copies of
|
|
# this and some confusion at run-time as to which class to use. This
|
|
# is an issue when we use NAMESPACES as we may need to export certain
|
|
# classes.
