Member Function Documentation

canScanForPlugins()

bool juce::LADSPAPluginFormat::canScanForPlugins ( ) const

inlineoverridevirtual

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

Implements juce::AudioPluginFormat.

References JUCE_DECLARE_NON_COPYABLE_WITH_LEAK_DETECTOR.

createInstanceFromDescription() [1/2]

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

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 juce::AudioPluginFormat.

createPluginInstanceAsync() [1/2]

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

inherited

doesPluginStillExist()

bool juce::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 juce::AudioPluginFormat.

fileMightContainThisPluginType()

bool juce::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 juce::AudioPluginFormat.

findAllTypesForFile()

void juce::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 juce::AudioPluginFormat.

getDefaultLocationsToSearch()

FileSearchPath juce::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 juce::AudioPluginFormat.

getName()

String juce::LADSPAPluginFormat::getName ( ) const

inlineoverridevirtual

Returns the format name.

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

Implements juce::AudioPluginFormat.

getNameOfPluginFromIdentifier()

String juce::LADSPAPluginFormat::getNameOfPluginFromIdentifier ( const String &  fileOrIdentifier )

overridevirtual

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

Implements juce::AudioPluginFormat.

pluginNeedsRescanning()

bool juce::LADSPAPluginFormat::pluginNeedsRescanning ( const PluginDescription &  )

overridevirtual

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

Implements juce::AudioPluginFormat.

recursiveFileSearch()

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

private

requiresUnblockedMessageThreadDuringCreation()

bool juce::LADSPAPluginFormat::requiresUnblockedMessageThreadDuringCreation ( const PluginDescription &  ) const

overrideprivatevirtualnoexcept

Implements juce::AudioPluginFormat.

searchPathsForPlugins()

StringArray juce::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.
