Detailed Description

Implements a plugin format for VST3s.

Constructor & Destructor Documentation

◆ VST3PluginFormat()

VST3PluginFormat::VST3PluginFormat ( )

Constructor.

◆ ~VST3PluginFormat()

VST3PluginFormat::~VST3PluginFormat ( )

override

Destructor.

Member Function Documentation

◆ setStateFromVSTPresetFile()

static bool VST3PluginFormat::setStateFromVSTPresetFile	(	AudioPluginInstance *	,
		const MemoryBlock &
	)

static

Attempts to reload a VST3 plugin's state from some preset file data.

See also: VSTPluginFormat::loadFromFXBFile

◆ getFormatName()

static String VST3PluginFormat::getFormatName ( )

static

◆ getName()

String VST3PluginFormat::getName ( ) const

overridevirtual

Returns the format name.

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

Implements AudioPluginFormat.

◆ canScanForPlugins()

bool VST3PluginFormat::canScanForPlugins ( ) const

overridevirtual

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

Implements AudioPluginFormat.

◆ isTrivialToScan()

bool VST3PluginFormat::isTrivialToScan ( ) const

overridevirtual

Should return true if this format is both safe and quick to scan - i.e.

if a file can be scanned within a few milliseconds on a background thread, without actually needing to load an executable.

Implements AudioPluginFormat.

◆ findAllTypesForFile()

void VST3PluginFormat::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.

◆ fileMightContainThisPluginType()

bool VST3PluginFormat::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.

◆ getNameOfPluginFromIdentifier()

String VST3PluginFormat::getNameOfPluginFromIdentifier ( const String & fileOrIdentifier )

overridevirtual

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

Implements AudioPluginFormat.

◆ pluginNeedsRescanning()

bool VST3PluginFormat::pluginNeedsRescanning ( const PluginDescription & )

overridevirtual

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

Implements AudioPluginFormat.

◆ searchPathsForPlugins()

StringArray VST3PluginFormat::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.

◆ doesPluginStillExist()

bool VST3PluginFormat::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.

◆ getDefaultLocationsToSearch()

FileSearchPath VST3PluginFormat::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.
