Constructor & Destructor Documentation

VSTPluginFormat::VSTPluginFormat ( )

VSTPluginFormat::~VSTPluginFormat ( )

Member Function Documentation

static const XmlElement* VSTPluginFormat::getVSTXML ( AudioPluginInstance * plugin )

static

Attempts to retrieve the VSTXML data from a plugin.

Will return nullptr if the plugin isn't a VST, or if it doesn't have any VSTXML.

static bool VSTPluginFormat::loadFromFXBFile	(	AudioPluginInstance *	plugin,
		const void *	data,
		size_t	dataSize
	)

static

Attempts to reload a VST plugin's state from some FXB or FXP data.

static bool VSTPluginFormat::saveToFXBFile	(	AudioPluginInstance *	plugin,
		MemoryBlock &	result,
		bool	asFXB
	)

static

Attempts to save a VST's state to some FXP or FXB data.

static bool VSTPluginFormat::getChunkData	(	AudioPluginInstance *	plugin,
		MemoryBlock &	result,
		bool	isPreset
	)

static

Attempts to get a VST's state as a chunk of memory.

static bool VSTPluginFormat::setChunkData	(	AudioPluginInstance *	plugin,
		const void *	data,
		int	size,
		bool	isPreset
	)

static

Attempts to set a VST's state from a chunk of memory.

static void VSTPluginFormat::setExtraFunctions	(	AudioPluginInstance *	plugin,
		ExtraFunctions *	functions
	)

static

Provides an ExtraFunctions callback object for a plugin to use.

The plugin will take ownership of the object and will delete it automatically.

static VstIntPtr JUCE_CALLTYPE VSTPluginFormat::dispatcher	(	AudioPluginInstance *	,
		int32	,
		int32	,
		VstIntPtr	,
		void *	,
		float
	)

static

This simply calls directly to the VST's AEffect::dispatcher() function.

String VSTPluginFormat::getName ( ) const

overridevirtual

Returns the format name.

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

Implements AudioPluginFormat.

void VSTPluginFormat::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.

bool VSTPluginFormat::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.

String VSTPluginFormat::getNameOfPluginFromIdentifier ( const String & fileOrIdentifier )

overridevirtual

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

Implements AudioPluginFormat.

bool VSTPluginFormat::pluginNeedsRescanning ( const PluginDescription & )

overridevirtual

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

Implements AudioPluginFormat.

StringArray VSTPluginFormat::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.

Implements AudioPluginFormat.

bool VSTPluginFormat::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.

FileSearchPath VSTPluginFormat::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.

bool VSTPluginFormat::canScanForPlugins ( ) const

overridevirtual

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

Implements AudioPluginFormat.

References JUCE_DECLARE_NON_COPYABLE_WITH_LEAK_DETECTOR.

virtual void VSTPluginFormat::aboutToScanVSTShellPlugin ( const PluginDescription & )

virtual

Can be overridden to receive a callback when each member of a shell plugin is about to be tested during a call to findAllTypesForFile().

Only the name and uid members of the PluginDescription are guaranteed to be valid when this is called.
