The key is unique within the data type. More...
class	IPlayer
	The main player classA player is responsible for the playback of a specific scenario. This player scenario is provided at initialisation stage and should not be changed until the player terminates. The player idea of calling a "play" function forces the use of threads in order to avoid CPU locking. Thus we prefer the idea of having a "short-time" function that is to be called repeatedly until the player terminates. This is the role of the `IPlayer::loop` function, that should be called repeatedly by the outside application. More...

OpenViBE::Kernel::ILogManager& OpenViBE::Kernel::operator<<	(	OpenViBE::Kernel::ILogManager &	rLogManager,
		const T &	rObject
	)

Stream output operator.

Parameters:

rLogManager	[in] : the log manager that takes the object
rObject	[in] : the object to log

Returns:: The log manager itself

See also:: OpenViBE::Kernel::ILogManager

This function helps in logging different objects thanks to the stream operator. The log manager can almost be used as any std ostream object.
