CProgProcess
Overview
CProgProcess is a base class for Program objects that process data
samples from a source IO and publish the results to an output IO.
This class provides the infrastructure for callback-driven sample
processing. It automatically handles the binding to source and output IOs
and registers a notification callback. When the source IO provides new data,
the derived class’s handle() method is called to perform the actual
processing.
The output object is producer-owned by the program path. During init(),
CProgProcess initializes deferred virt outputs when needed and
validates configured writable outputs against the resolved source shape.
A common pattern is to use the CProgProcessTemplate, which allows
implementing the processing logic once and applying it to different
data types (like integers or floats) through a simple policy class.
