Constructor & Destructor Documentation

◆ AudioPluginFormatManager()

juce::AudioPluginFormatManager::AudioPluginFormatManager ( )

Definition at line 29 of file juce_AudioPluginFormatManager.cpp.

◆ ~AudioPluginFormatManager()

Destructor.

Member Function Documentation

◆ addDefaultFormats()

void juce::AudioPluginFormatManager::addDefaultFormats ( )

Adds the set of available standard formats, e.g.

VST.

Definition at line 33 of file juce_AudioPluginFormatManager.cpp.

◆ addFormat()

void juce::AudioPluginFormatManager::addFormat ( AudioPluginFormat * format )

Adds a format to the list.

The object passed in will be owned and deleted by the manager.

Definition at line 122 of file juce_AudioPluginFormatManager.cpp.

◆ createARAFactoryAsync()

void juce::AudioPluginFormatManager::createARAFactoryAsync	(	const PluginDescription &	description,
		AudioPluginFormat::ARAFactoryCreationCallback	callback
	)		const

Tries to create an ::ARAFactoryWrapper for this description.

The result of the operation will be wrapped into an ARAFactoryResult, which will be passed to a callback object supplied by the caller.

The operation may fail, in which case the callback will be called with with a result object where ARAFactoryResult::araFactory.get() will return a nullptr.

In case of success the returned ::ARAFactoryWrapper will ensure that modules required for the correct functioning of the ARAFactory will remain loaded for the lifetime of the object.

◆ createPluginInstance()

std::unique_ptr< AudioPluginInstance > juce::AudioPluginFormatManager::createPluginInstance	(	const PluginDescription &	description,
		double	initialSampleRate,
		int	initialBufferSize,
		String &	errorMessage
	)		const

Tries to load the type for this description, by trying all the formats that this manager knows about.

If it can't load the plugin, it returns nullptr and leaves a message in the errorMessage string.

If you intend to instantiate a AudioUnit v3 plug-in then you must either use the non-blocking asynchronous version below - or call this method from a thread other than the message thread and without blocking the message thread.

Definition at line 127 of file juce_AudioPluginFormatManager.cpp.

◆ createPluginInstanceAsync()

void juce::AudioPluginFormatManager::createPluginInstanceAsync	(	const PluginDescription &	description,
		double	initialSampleRate,
		int	initialBufferSize,
		AudioPluginFormat::PluginCreationCallback	callback
	)

Tries to asynchronously load the type for this description, by trying all the formats that this manager knows about.

The caller must supply a callback object which will be called when the instantiation has completed.

If it can't load the plugin then the callback function will be called passing a nullptr as the instance argument along with an error message.

The callback function will be called on the message thread so the caller must not block the message thread.

The callback object will be deleted automatically after it has been invoked.

The caller is responsible for deleting the instance that is passed to the callback function.

If you intend to instantiate a AudioUnit v3 plug-in then you must use this non-blocking asynchronous version - or call the synchronous method from an auxiliary thread.
