Class Documentation

OcmDaqService

class OcmDaqService

Implements the MAL interface daqif::OcmDaq (async version).

The server is only safe to use as a shared pointer, as weak pointers to this object is stored in asynchronous continuations, apart from the initiating operation. Provided boost::asio::io_context must outlive object and any pending operations.

This object can be deleted while there are operations that have not complete yet. In that case, when the operation finally completes, an exception is sent as reply, even if the requested operation would have succeeded otherwise. The io_context must stay alive however, as it will be used as an executor when asynchonous operation is continued.

A note on thread safety:

The public (asynchronous) interface will immediately defer the execution to the provided executor, so depending on the executor this can provide thread safety.

Constructor & Destructor Documentation

OcmDaqService()

OcmDaqService::OcmDaqService	(	boost::asio::io_context &	io_ctx,
		mal::Mal &	mal,
		daq::Manager &	mgr,
		std::string	proc_name,
		std::string	output_path,
		std::shared_ptr< daq::ObservableEventLog >	event_log
	)

Parameters

io_ctx	ASIO io context to use as an executor. This object must outlive OcmDaqService. The io context will be progated to any created daq::DaqController instances as well.
mal	The mal instance to use to create instances. This object must outlive OcmDaqService.
mgr	The data acquisition manager to use. This object must outlive OcmDaqService.
