Constructor & Destructor Documentation

◆ FileSearchPath() [1/3]

juce::FileSearchPath::FileSearchPath ( )

Creates an empty search path.

◆ FileSearchPath() [2/3]

juce::FileSearchPath::FileSearchPath ( const String & path )

Creates a search path from a string of pathnames.

The path can be semicolon- or comma-separated, e.g. "/foo/bar;/foo/moose;/fish/moose"

The separate folders are tokenised and added to the search path.

◆ FileSearchPath() [3/3]

juce::FileSearchPath::FileSearchPath ( const FileSearchPath & )

Creates a copy of another search path.

◆ ~FileSearchPath()

juce::FileSearchPath::~FileSearchPath ( )

Destructor.

Member Function Documentation

◆ add()

void juce::FileSearchPath::add	(	const File &	directoryToAdd,
		int	insertIndex = `-1`
	)

Adds a new directory to the search path.

The new directory is added to the end of the list if the insertIndex parameter is less than zero, otherwise it is inserted at the given index.

◆ addIfNotAlreadyThere()

bool juce::FileSearchPath::addIfNotAlreadyThere ( const File & directoryToAdd )

Adds a new directory to the search path if it's not already in there.

Returns: true if the directory has been added, false otherwise.

◆ addPath()

void juce::FileSearchPath::addPath ( const FileSearchPath & )

Merges another search path into this one.

This will remove any duplicate directories.

◆ findChildFiles() [1/2]

Array<File> juce::FileSearchPath::findChildFiles	(	int	whatToLookFor,
		bool	searchRecursively,
		const String &	wildCardPattern = `"*"`
	)		const

Searches the path for a wildcard.

This will search all the directories in the search path in order and return an array of the files that were found.

Parameters

whatToLookFor	a value from the File::TypesOfFileToFind enum, specifying whether to return files, directories, or both.
searchRecursively	whether to recursively search the subdirectories too
wildCardPattern	a pattern to match against the filenames

Returns: the number of files added to the array

See also: File::findChildFiles

◆ findChildFiles() [2/2]

int juce::FileSearchPath::findChildFiles	(	Array< File > &	results,
		int	whatToLookFor,
		bool	searchRecursively,
		const String &	wildCardPattern = `"*"`
	)		const

Searches the path for a wildcard.

Note that there's a newer, better version of this method which returns the results array, and in almost all cases, you should use that one instead! This one is kept around mainly for legacy code to use.

◆ getNumPaths()

int juce::FileSearchPath::getNumPaths ( ) const

Returns the number of folders in this search path.

See also: operator[]

◆ init()

void juce::FileSearchPath::init ( const String & )

private

◆ isFileInPath()

bool juce::FileSearchPath::isFileInPath	(	const File &	fileToCheck,
		bool	checkRecursively
	)		const

Finds out whether a file is inside one of the path's directories.

This will return true if the specified file is a child of one of the directories specified by this path. Note that this doesn't actually do any searching or check that the files exist - it just looks at the pathnames to work out whether the file would be inside a directory.

Parameters

fileToCheck	the file to look for
checkRecursively	if true, then this will return true if the file is inside a subfolder of one of the path's directories (at any depth). If false it will only return true if the file is actually a direct child of one of the directories.

◆ operator=() [1/2]

FileSearchPath& juce::FileSearchPath::operator= ( const FileSearchPath & )

Copies another search path.

◆ operator=() [2/2]

FileSearchPath& juce::FileSearchPath::operator= ( const String & path )

Uses a string containing a list of pathnames to re-initialise this list.

This search path is cleared and the semicolon- or comma-separated folders in this string are added instead. e.g. "/foo/bar;/foo/moose;/fish/moose"

◆ operator[]()

File juce::FileSearchPath::operator[] ( int index ) const

Returns one of the folders in this search path.

The file returned isn't guaranteed to actually be a valid directory.

See also: getNumPaths

◆ remove()

void juce::FileSearchPath::remove ( int indexToRemove )

Removes a directory from the search path.

◆ removeNonExistentPaths()

void juce::FileSearchPath::removeNonExistentPaths ( )

Removes any directories that don't actually exist.

◆ removeRedundantPaths()

void juce::FileSearchPath::removeRedundantPaths ( )

Removes any directories that are actually subdirectories of one of the other directories in the search path.

If the search is intended to be recursive, there's no point having nested folders in the search path, because they'll just get searched twice and you'll get duplicate results.

e.g. if the path is "c:\abc\de;c:\abc", this method will simplify it to "c:\abc"

◆ toString()

String juce::FileSearchPath::toString ( ) const

Returns the search path as a semicolon-separated list of directories.
