Detailed Description

Describes the layout and properties of an audio bus. Effectively a bus description is a named set of channel types.

Constructor & Destructor Documentation

		const String &	busName,
		const AudioChannelSet &	defaultLayout,
		bool	isDfltEnabled )

private

Member Function Documentation

◆ enable()

bool juce::AudioProcessor::Bus::enable ( bool shouldEnable = true )

Enable or disable this bus. This will return false if the AudioProcessor does not support disabling this bus.

◆ getBusBuffer()

template<typename FloatType>

AudioBuffer< FloatType > juce::AudioProcessor::Bus::getBusBuffer ( AudioBuffer< FloatType > & processBlockBuffer ) const

inline

Returns an AudioBuffer containing a set of channel pointers for a specific bus. This can be called in processBlock to get a buffer containing a sub-group of the master AudioBuffer which contains all the plugin channels.

◆ getBusesLayoutForLayoutChangeOfBus()

AudioProcessor::BusesLayout juce::AudioProcessor::Bus::getBusesLayoutForLayoutChangeOfBus ( const AudioChannelSet & set ) const

Returns the resulting layouts of all buses after changing the layout of this bus.

Changing an individual layout of a bus may also change the layout of all the other buses. This method returns what the layouts of all the buses of the audio processor would be, if you were to change the layout of this bus to the given layout. If there is no way to support the given layout then this method will return the next best layout.

◆ getBusIndex()

int juce::AudioProcessor::Bus::getBusIndex ( ) const

noexcept

Returns the index of this bus.

◆ getChannelIndexInProcessBlockBuffer()

int juce::AudioProcessor::Bus::getChannelIndexInProcessBlockBuffer ( int channelIndex ) const

noexcept

Returns the position of a bus's channels within the processBlock buffer. This can be called in processBlock to figure out which channel of the master AudioBuffer maps onto a specific bus's channel.

◆ getCurrentLayout()

const AudioChannelSet & juce::AudioProcessor::Bus::getCurrentLayout ( ) const

inlinenoexcept

The bus's current layout. This will be AudioChannelSet::disabled() if the current layout is disabled.

See also: AudioChannelSet

◆ getDefaultLayout()

const AudioChannelSet & juce::AudioProcessor::Bus::getDefaultLayout ( ) const

inlinenoexcept

Get the default layout of this bus.

See also: AudioChannelSet

◆ getDirectionAndIndex()

AudioProcessor::Bus::BusDirectionAndIndex juce::AudioProcessor::Bus::getDirectionAndIndex ( ) const

privatenoexcept

◆ getLastEnabledLayout()

const AudioChannelSet & juce::AudioProcessor::Bus::getLastEnabledLayout ( ) const

inlinenoexcept

Return the bus's last active channel layout. If the bus is currently enabled then the result will be identical to getCurrentLayout otherwise it will return the last enabled layout.

See also: AudioChannelSet

◆ getMaxSupportedChannels()

int juce::AudioProcessor::Bus::getMaxSupportedChannels ( int limit = AudioChannelSet::maxChannelsOfNamedLayout ) const

Returns the maximum number of channels that this bus can support.

Parameters

limit The maximum value to return.

◆ getName()

const String & juce::AudioProcessor::Bus::getName ( ) const

inlinenoexcept

The bus's name.

◆ getNumberOfChannels()

int juce::AudioProcessor::Bus::getNumberOfChannels ( ) const

inlinenoexcept

Return the number of channels of the current bus.

◆ isEnabled()

bool juce::AudioProcessor::Bus::isEnabled ( ) const

inlinenoexcept

Returns true if the current bus is enabled.

◆ isEnabledByDefault()

bool juce::AudioProcessor::Bus::isEnabledByDefault ( ) const

inlinenoexcept

Returns if this bus is enabled by default.

◆ isInput()

bool juce::AudioProcessor::Bus::isInput ( ) const

noexcept

Returns true if this bus is an input bus.

◆ isLayoutSupported()

bool juce::AudioProcessor::Bus::isLayoutSupported	(	const AudioChannelSet &	set,
		BusesLayout *	currentLayout = nullptr ) const

Checks if a particular layout is supported.

Parameters

set	The AudioChannelSet which is to be probed.
currentLayout	If non-null, pretend that the current layout of the AudioProcessor is currentLayout. On exit, currentLayout will be modified to to represent the buses layouts of the AudioProcessor as if the layout of the receiver had been successfully changed. This is useful as changing the layout of the receiver may change the bus layout of other buses.

See also: AudioChannelSet

◆ isMain()

bool juce::AudioProcessor::Bus::isMain ( ) const

inlinenoexcept

Returns true if the current bus is the main input or output bus.

◆ isNumberOfChannelsSupported()

bool juce::AudioProcessor::Bus::isNumberOfChannelsSupported ( int channels ) const

Checks if this bus can support a given number of channels.

◆ setCurrentLayout()

bool juce::AudioProcessor::Bus::setCurrentLayout ( const AudioChannelSet & layout )

Sets the bus's current layout. If the AudioProcessor does not support this layout then this will return false.

See also: AudioChannelSet

◆ setCurrentLayoutWithoutEnabling()

bool juce::AudioProcessor::Bus::setCurrentLayoutWithoutEnabling ( const AudioChannelSet & layout )

Sets the bus's current layout without changing the enabled state. If the AudioProcessor does not support this layout then this will return false.

See also: AudioChannelSet

◆ setNumberOfChannels()

bool juce::AudioProcessor::Bus::setNumberOfChannels ( int channels )

Set the number of channels of this bus. This will return false if the AudioProcessor does not support this layout.

◆ supportedLayoutWithChannels()

AudioChannelSet juce::AudioProcessor::Bus::supportedLayoutWithChannels ( int channels ) const

Returns a ChannelSet that the bus supports with a given number of channels.

◆ updateChannelCount()

void juce::AudioProcessor::Bus::updateChannelCount ( )
