Constructor & Destructor Documentation

KnownPluginList()

KnownPluginList::KnownPluginList

(

)

Creates an empty list.

~KnownPluginList()

KnownPluginList::~KnownPluginList ( )

override

Destructor.

Member Function Documentation

clear()

void KnownPluginList::clear

(

)

Clears the list.

addType()

bool KnownPluginList::addType

(

const PluginDescription &

type

)

Adds a type manually from its description.

removeType()

void KnownPluginList::removeType

(

const PluginDescription &

type

)

Removes a type.

getNumTypes()

int KnownPluginList::getNumTypes ( ) const

noexcept

Returns the number of types currently in the list.

getTypes()

Array< PluginDescription > KnownPluginList::getTypes

(

)

const

Returns a copy of the current list.

getTypesForFormat()

Array< PluginDescription > KnownPluginList::getTypesForFormat

(

AudioPluginFormat &

)

const

Returns the subset of plugin types for a given format.

getTypeForFile()

std::unique_ptr< PluginDescription > KnownPluginList::getTypeForFile

(

const String &

fileOrIdentifier

)

const

Looks for a type in the list which comes from this file.

getTypeForIdentifierString()

std::unique_ptr< PluginDescription > KnownPluginList::getTypeForIdentifierString

(

const String &

identifierString

)

const

Looks for a type in the list which matches a plugin type ID.

The identifierString parameter must have been created by PluginDescription::createIdentifierString().

scanAndAddFile()

bool KnownPluginList::scanAndAddFile	(	const String &	possiblePluginFileOrIdentifier,
		bool	dontRescanIfAlreadyInList,
		OwnedArray< PluginDescription > &	typesFound,
		AudioPluginFormat &	formatToUse )

Looks for all types that can be loaded from a given file, and adds them to the list.

If dontRescanIfAlreadyInList is true, then the file will only be loaded and re-tested if it's not already in the list, or if the file's modification time has changed since the list was created. If dontRescanIfAlreadyInList is false, the file will always be reloaded and tested.

Returns true if any new types were added, and all the types found in this file (even if it was already known and hasn't been re-scanned) get returned in the array.

scanFinished()

void KnownPluginList::scanFinished

(

)

Tells a custom scanner that a scan has finished, and it can release any resources.

isListingUpToDate()

bool KnownPluginList::isListingUpToDate	(	const String &	possiblePluginFileOrIdentifier,
		AudioPluginFormat &	formatToUse ) const

Returns true if the specified file is already known about and if it hasn't been modified since our entry was created.

scanAndAddDragAndDroppedFiles()

void KnownPluginList::scanAndAddDragAndDroppedFiles	(	AudioPluginFormatManager &	formatManager,
		const StringArray &	filenames,
		OwnedArray< PluginDescription > &	typesFound )

Scans and adds a bunch of files that might have been dragged-and-dropped.

If any types are found in the files, their descriptions are returned in the array.

getBlacklistedFiles()

const StringArray & KnownPluginList::getBlacklistedFiles

(

)

const

Returns the list of blacklisted files.

addToBlacklist()

void KnownPluginList::addToBlacklist

(

const String &

pluginID

)

Adds a plugin ID to the black-list.

removeFromBlacklist()

void KnownPluginList::removeFromBlacklist

(

const String &

pluginID

)

Removes a plugin ID from the black-list.

clearBlacklistedFiles()

void KnownPluginList::clearBlacklistedFiles

(

)

Clears all the blacklisted files.

addToMenu()

static void KnownPluginList::addToMenu ( PopupMenu & menu, const Array< PluginDescription > & types, SortMethod sortMethod, const String & currentlyTickedPluginID = {} )

static

Adds the plug-in types to a popup menu so that the user can select one.

Depending on the sort method, it may add sub-menus for categories, manufacturers, etc.

Use getIndexChosenByMenu() to find out the type that was chosen.

getIndexChosenByMenu()

static int KnownPluginList::getIndexChosenByMenu ( const Array< PluginDescription > & types, int menuResultCode )

static

Converts a menu item index that has been chosen into its index in the list.

Returns -1 if it's not an ID that was used.

addToMenu

sort()

void KnownPluginList::sort	(	SortMethod	method,
		bool	forwards )

Sorts the list.

createXml()

std::unique_ptr< XmlElement > KnownPluginList::createXml

(

)

const

Creates some XML that can be used to store the state of this list.

recreateFromXml()

void KnownPluginList::recreateFromXml

(

const XmlElement &

xml

)

Recreates the state of this list from its stored XML format.

createTree()

static std::unique_ptr< PluginTree > KnownPluginList::createTree ( const Array< PluginDescription > & types, SortMethod sortMethod )

static

Creates a PluginTree object representing the list of plug-ins.

setCustomScanner()

void KnownPluginList::setCustomScanner

(

std::unique_ptr< CustomScanner >

newScanner

)

Supplies a custom scanner to be used in future scans.

The KnownPluginList will take ownership of the object passed in.
