◆ canScanForPlugins()

virtual bool juce::AudioPluginFormat::canScanForPlugins ( ) const

pure virtual

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

Implemented in juce::VSTPluginFormat, juce::VST3PluginFormat, juce::AudioUnitPluginFormat, and juce::LADSPAPluginFormat.

◆ createInstanceFromDescription() [1/2]

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

Tries to recreate a type from a previously generated PluginDescription.

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

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

virtual void juce::AudioPluginFormat::createPluginInstance	(	const PluginDescription &	,
		double	initialSampleRate,
		int	initialBufferSize,
		void *	userData,
		PluginCreationCallback
	)

protectedpure virtual

Implementors must override this function.

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

Implemented in juce::VSTPluginFormat, juce::VST3PluginFormat, juce::AudioUnitPluginFormat, and juce::LADSPAPluginFormat.

◆ createPluginInstanceAsync() [1/2]

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

Tries to recreate a type from a previously generated PluginDescription.

◆ createPluginInstanceAsync() [2/2]

void juce::AudioPluginFormat::createPluginInstanceAsync	(	const PluginDescription &	description,

		std::function< void(AudioPluginInstance *, const String &)>	completionCallback

◆ doesPluginStillExist()

virtual bool juce::AudioPluginFormat::doesPluginStillExist ( const PluginDescription & )

pure virtual

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.

Implemented in juce::VSTPluginFormat, juce::VST3PluginFormat, juce::AudioUnitPluginFormat, and juce::LADSPAPluginFormat.

◆ fileMightContainThisPluginType()

virtual bool juce::AudioPluginFormat::fileMightContainThisPluginType ( const String & fileOrIdentifier )

pure virtual

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.

Implemented in juce::VSTPluginFormat, juce::VST3PluginFormat, juce::AudioUnitPluginFormat, and juce::LADSPAPluginFormat.

◆ findAllTypesForFile()

virtual void juce::AudioPluginFormat::findAllTypesForFile	(	OwnedArray< PluginDescription > &	results,
		const String &	fileOrIdentifier
	)

pure virtual

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.

Implemented in juce::VSTPluginFormat, juce::VST3PluginFormat, juce::AudioUnitPluginFormat, and juce::LADSPAPluginFormat.

◆ getDefaultLocationsToSearch()

virtual FileSearchPath juce::AudioPluginFormat::getDefaultLocationsToSearch ( )

pure virtual

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.

Implemented in juce::VSTPluginFormat, juce::VST3PluginFormat, juce::AudioUnitPluginFormat, and juce::LADSPAPluginFormat.

◆ getName()

virtual String juce::AudioPluginFormat::getName ( ) const

pure virtual

Returns the format name.

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

Implemented in juce::VSTPluginFormat, juce::VST3PluginFormat, juce::AudioUnitPluginFormat, and juce::LADSPAPluginFormat.

◆ getNameOfPluginFromIdentifier()

virtual String juce::AudioPluginFormat::getNameOfPluginFromIdentifier ( const String & fileOrIdentifier )

pure virtual

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

Implemented in juce::VSTPluginFormat, juce::VST3PluginFormat, juce::AudioUnitPluginFormat, and juce::LADSPAPluginFormat.

◆ pluginNeedsRescanning()

virtual bool juce::AudioPluginFormat::pluginNeedsRescanning ( const PluginDescription & )

pure virtual

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

Implemented in juce::VSTPluginFormat, juce::VST3PluginFormat, juce::AudioUnitPluginFormat, and juce::LADSPAPluginFormat.

◆ requiresUnblockedMessageThreadDuringCreation()

virtual bool juce::AudioPluginFormat::requiresUnblockedMessageThreadDuringCreation ( const PluginDescription & ) const

protectedpure virtualnoexcept

Implemented in juce::VSTPluginFormat, juce::VST3PluginFormat, juce::AudioUnitPluginFormat, and juce::LADSPAPluginFormat.

◆ searchPathsForPlugins()

virtual StringArray juce::AudioPluginFormat::searchPathsForPlugins	(	const FileSearchPath &	directoriesToSearch,
		bool	recursive,
		bool	allowPluginsWhichRequireAsynchronousInstantiation = `false`
	)

pure virtual

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.

Implemented in juce::VSTPluginFormat, juce::VST3PluginFormat, juce::AudioUnitPluginFormat, and juce::LADSPAPluginFormat.
