• op – The pointer to the GXFOperator object.

• outputs – outputs The references to the map of the output specs.

gxf_context_t gxf_context() const

Get pointer to the GXF execution runtime.

Returns

The pointer to the GXF context.

Protected Functions

virtual void emit_impl(std::any data, const char *name = nullptr, OutputType out_type = OutputType::kSharedPointer) override
