Constructor & Destructor Documentation

◆ BufferedSwitchMatrixInputChannel()

BufferedSwitchMatrixInputChannel::BufferedSwitchMatrixInputChannel	(	const std::string &	hwname,
		SwitchMatrix *	parent,
		const std::string &	color = `"#808080"`,
		size_t	index = `0`
	)

Initialize the channel.

Parameters

hwname	Hardware name of the channel
parent	Switch matrix the channel is part of
color	Initial display color of the channel
index	Number of the channel

Member Function Documentation

◆ OnInputChanged()

void BufferedSwitchMatrixInputChannel::OnInputChanged ( size_t i )

overridevirtual

Called when a new input is connected to the node.

The default implementation does nothing, but some special cases may find this hook useful.

For example, instrument channels may make hardware changes as soon as a new input is connected.

Reimplemented from FlowGraphNode.

◆ SetMuxInputThreshold()

void BufferedSwitchMatrixInputChannel::SetMuxInputThreshold ( float v )

inline

Sets the input port threshold voltage.
