Member Function Documentation

◆ canScanForPlugins()

bool LADSPAPluginFormat::canScanForPlugins ( ) const

inlineoverridevirtual

Returns true if this format needs to run a scan to find its list of plugins.

Implements AudioPluginFormat.

References AudioPluginFormat::createPluginInstance(), JUCE_DECLARE_NON_COPYABLE_WITH_LEAK_DETECTOR, and AudioPluginFormat::requiresUnblockedMessageThreadDuringCreation().

◆ createInstanceFromDescription() [1/2]

AudioPluginInstance* AudioPluginFormat::createInstanceFromDescription	(	const PluginDescription &	,
		double	initialSampleRate,
		int	initialBufferSize
	)

inherited

Tries to recreate a type from a previously generated PluginDescription.

See also: AudioPluginFormatManager::createInstance

◆ createInstanceFromDescription() [2/2]

AudioPluginInstance* AudioPluginFormat::createInstanceFromDescription	(	const PluginDescription &	,
		double	initialSampleRate,
		int	initialBufferSize,
		String &	errorMessage
	)

inherited

Same as above but with the possibility of returning an error message.

See also: AudioPluginFormatManager::createInstance

◆ createPluginInstance()

void LADSPAPluginFormat::createPluginInstance	(	const PluginDescription &	,
		double	initialSampleRate,
		int	initialBufferSize,
		void *	userData,
		void()(void , AudioPluginInstance *, const String &)	callback
	)

overrideprivatevirtual

Implementors must override this function.

This is guaranteed to be called on the message thread. You may call the callback on any thread.

Implements AudioPluginFormat.

◆ createPluginInstanceAsync() [1/2]

void AudioPluginFormat::createPluginInstanceAsync	(	const PluginDescription &	description,
		double	initialSampleRate,
		int	initialBufferSize,
		InstantiationCompletionCallback *	completionCallback
	)

inherited

Tries to recreate a type from a previously generated PluginDescription.

See also: AudioPluginFormatManager::createInstanceAsync

◆ createPluginInstanceAsync() [2/2]

void AudioPluginFormat::createPluginInstanceAsync	(	const PluginDescription &	description,
		double	initialSampleRate,
		int	initialBufferSize,
		std::function< void(AudioPluginInstance *, const String &)>	completionCallback
	)

inherited

◆ doesPluginStillExist()

bool LADSPAPluginFormat::doesPluginStillExist ( const PluginDescription & )

overridevirtual

Checks whether this plugin could possibly be loaded.

It doesn't actually need to load it, just to check whether the file or component still exists.

Implements AudioPluginFormat.

◆ fileMightContainThisPluginType()

bool LADSPAPluginFormat::fileMightContainThisPluginType ( const String & fileOrIdentifier )

overridevirtual

Should do a quick check to see if this file or directory might be a plugin of this format.

This is for searching for potential files, so it shouldn't actually try to load the plugin or do anything time-consuming.

Implements AudioPluginFormat.

◆ findAllTypesForFile()

void LADSPAPluginFormat::findAllTypesForFile	(	OwnedArray< PluginDescription > &	results,
		const String &	fileOrIdentifier
	)

overridevirtual

This tries to create descriptions for all the plugin types available in a binary module file.

The file will be some kind of DLL or bundle.

Normally there will only be one type returned, but some plugins (e.g. VST shells) can use a single DLL to create a set of different plugin subtypes, so in that case, each subtype is returned as a separate object.

Implements AudioPluginFormat.

◆ getDefaultLocationsToSearch()

FileSearchPath LADSPAPluginFormat::getDefaultLocationsToSearch ( )

overridevirtual

Returns the typical places to look for this kind of plugin.

Note that if this returns no paths, it means that the format doesn't search in files or folders, e.g. AudioUnits.

Implements AudioPluginFormat.

◆ getName()

String LADSPAPluginFormat::getName ( ) const

inlineoverridevirtual

Returns the format name.

E.g. "VST", "AudioUnit", etc.

Implements AudioPluginFormat.

References AudioPluginFormat::doesPluginStillExist(), AudioPluginFormat::fileMightContainThisPluginType(), AudioPluginFormat::findAllTypesForFile(), AudioPluginFormat::getDefaultLocationsToSearch(), AudioPluginFormat::getNameOfPluginFromIdentifier(), AudioPluginFormat::pluginNeedsRescanning(), and AudioPluginFormat::searchPathsForPlugins().

◆ getNameOfPluginFromIdentifier()

String LADSPAPluginFormat::getNameOfPluginFromIdentifier ( const String & fileOrIdentifier )

overridevirtual

Returns a readable version of the name of the plugin that this identifier refers to.

Implements AudioPluginFormat.

◆ pluginNeedsRescanning()

bool LADSPAPluginFormat::pluginNeedsRescanning ( const PluginDescription & )

overridevirtual

Returns true if this plugin's version or date has changed and it should be re-checked.

Implements AudioPluginFormat.

◆ recursiveFileSearch()

void LADSPAPluginFormat::recursiveFileSearch	(	StringArray &	,
		const File &	,
		bool	recursive
	)

private

◆ requiresUnblockedMessageThreadDuringCreation()

bool LADSPAPluginFormat::requiresUnblockedMessageThreadDuringCreation ( const PluginDescription & ) const

overrideprivatevirtualnoexcept

Implements AudioPluginFormat.

◆ searchPathsForPlugins()

StringArray LADSPAPluginFormat::searchPathsForPlugins	(	const FileSearchPath &	directoriesToSearch,
		bool	recursive,
		bool	allowPluginsWhichRequireAsynchronousInstantiation
	)

overridevirtual

Searches a suggested set of directories for any plugins in this format.

The path might be ignored, e.g. by AUs, which are found by the OS rather than manually.

Parameters

directoriesToSearch	This specifies which directories shall be searched for plug-ins.
recursive	Should the search recursively traverse folders.
allowPluginsWhichRequireAsynchronousInstantiation	If this is false then plug-ins which require asynchronous creation will be excluded.
