holoscan::StdPubSubEntitySerializer | Holoscan SDK Documentation

Adapter that bridges Holoscan’s StdEntitySerializer with GXF’s PubSubEntitySerializer.

StdPubSubEntitySerializer wraps a Holoscan StdEntitySerializer (which uses SerializationBuffer) and presents it via the GXF PubSubEntitySerializer interface (which works with std::vector<uint8_t>).

#include <holoscan/in_memory_pubsub_session.hpp>

Inherits from: nvidia::gxf::PubSubEntitySerializer (public)

This class is marked final.
