holoscan::AnnotatedDoubleBufferTransmitter

AnnotatedDoubleBufferTransmitter class tracks every published message by attaching a MessageLabel that has a timestamp.

Application authors are not expected to use this class directly. It will be automatically configured for output ports specified via Operator::setup when data flow tracking is enabled.

Methods

publish_abi

gxf_result_t holoscan::AnnotatedDoubleBufferTransmitter::publish_abi(
    gxf_uid_t uid
)

Override the DoubleBufferTransmitter::publish_abi() function.

It adds a MessageLabel to the publish GXF Entity and finally calls the base class’ publish_abi() function. It gets the input message labels of every operator and then adds that consolidated message label to the published message.

For root operators, it also updates the number of published messages.
