Detailed Description

Implements a plugin format manager for AudioUnits.

Constructor & Destructor Documentation

◆ AudioUnitPluginFormat()

AudioUnitPluginFormat::AudioUnitPluginFormat ( )

◆ ~AudioUnitPluginFormat()

AudioUnitPluginFormat::~AudioUnitPluginFormat ( )
override

Member Function Documentation

◆ getFormatName()

static String AudioUnitPluginFormat::getFormatName ( )
static

◆ getName()

String AudioUnitPluginFormat::getName ( ) const
overridevirtual

Returns the format name.

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

Implements AudioPluginFormat.

◆ canScanForPlugins()

bool AudioUnitPluginFormat::canScanForPlugins ( ) const
overridevirtual

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

Implements AudioPluginFormat.

◆ isTrivialToScan()

bool AudioUnitPluginFormat::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 AudioUnitPluginFormat::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 AudioUnitPluginFormat::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 AudioUnitPluginFormat::getNameOfPluginFromIdentifier ( const String & fileOrIdentifier)
overridevirtual

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

Implements AudioPluginFormat.

◆ pluginNeedsRescanning()

bool AudioUnitPluginFormat::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 AudioUnitPluginFormat::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
directoriesToSearchThis specifies which directories shall be searched for plug-ins.
recursiveShould the search recursively traverse folders.
allowPluginsWhichRequireAsynchronousInstantiationIf this is false then plug-ins which require asynchronous creation will be excluded.

Implements AudioPluginFormat.

◆ doesPluginStillExist()

bool AudioUnitPluginFormat::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 AudioUnitPluginFormat::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.

◆ createARAFactoryAsync()

void AudioUnitPluginFormat::createARAFactoryAsync ( const PluginDescription & ,
ARAFactoryCreationCallback callback )
overridevirtual

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.
