◆ alias() [1/2]

SignalPtr cloe::DataBroker::alias	(	SignalPtr	signal,
		std::string_view	new_name
	)

inline

Give an existing signal an alias.

Parameters

signal	Signal to be named
new_name	New name of the signal

Returns: Pointer to the signal

Note: If an exception is thrown by any operation, the aliasing has no effect.
