prof class is a simple container for managing profiler output
via R. The slots are profiler, raw, and parsed. The first,
profiler, is just a character string consisting of the profiler used
to generate the output (e.g., "fpmpi", "mpiP", etc.).
Next, the slot raw contains the raw output from the profiling library,
stored in R as a vector of character data (strings) directly from a
readLines() call, and cast as the virtual class rawprof. In
reality, we will cast the raw data as a virtual class of the same name as
that found in the profiler slot, and rawprof is a superclass
of each of these classes. This is for internal S3 dispatch. You should not
mess around with this.
The final slot, parsed, contains a condensed version of the
information from the raw slot, stored as a dataframe. This is the
representation used for plotting.
Unless you really think you know what you are doing, you probably shouldn't
directly mess around with the elements of this class. Instead, simply
use the read.prof() function.
