Member Function Documentation

virtual OpenViBE::boolean sendSignal

(

const OpenViBE::Kernel::IMessageSignal &

rMessageSignal

)

[pure virtual]

Sends signal to the kernel.

Parameters:

rMessageSignal

[in] : the signal message to send

Returns:

true in case of success, false in other cases.

virtual OpenViBE::boolean sendMessage	(	const OpenViBE::Kernel::IMessageEvent &	rMessageEvent,
		const OpenViBE::CIdentifier &	rTargetIdentifier
	)		[pure virtual]

Sends a message to another box.

Parameters:

rMessageEvent	[in] : the message to send to the other box
rTargetIdentifier	[in] : the identifier of the other box

Returns:

true in case of success, false in other cases.

virtual OpenViBE::boolean sendMessage	(	const OpenViBE::Kernel::IMessageEvent &	rMessageEvent,
		const OpenViBE::CIdentifier *	pTargetIdentifier,
		const OpenViBE::uint32	ui32TargetIdentifierCount
	)		[pure virtual]

Broadcasts a message to several other boxes.

Parameters:

rMessageEvent	[in] : the message to send
pTargetIdentifier	[in] : a pointer containing all the targets which should receive the sent message.
ui32TargetIdentifierCount	[in] : the number of targets contained in the pTargetIdentifier array.

Returns:

true in case of success, false in other cases.

virtual OpenViBE::uint64 getCurrentTime
