Constructor & Destructor Documentation

◆ FileSearchPath() [1/3]

FileSearchPath::FileSearchPath ( )
default

Creates an empty search path.

◆ ~FileSearchPath()

FileSearchPath::~FileSearchPath ( )
default

Destructor.

◆ FileSearchPath() [2/3]

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]

FileSearchPath::FileSearchPath ( const FileSearchPath & )

Creates a copy of another search path.

Member Function Documentation

◆ operator=() [1/2]

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

Copies another search path.

◆ operator=() [2/2]

FileSearchPath & 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"

◆ getNumPaths()

int FileSearchPath::getNumPaths ( ) const

Returns the number of folders in this search path.

See also
operator[]

◆ operator[]()

File 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, getRawString

◆ getRawString()

String FileSearchPath::getRawString ( int index) const

Returns the unaltered text of the folder at the specified index.

Unlike operator[], this function returns the exact text that was entered. It does not attempt to convert the path into an absolute path.

This may be useful if the directory string is expected to understand environment variables or other placeholders that the File constructor doesn't necessarily understand.

operator[]

◆ toString()

String FileSearchPath::toString ( ) const

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

◆ toStringWithSeparator()

String FileSearchPath::toStringWithSeparator ( StringRef separator) const

Returns the search paths, joined with the provided separator.

◆ add()

void 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 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.

◆ remove()

void FileSearchPath::remove ( int indexToRemove)

Removes a directory from the search path.

◆ addPath()

void FileSearchPath::addPath ( const FileSearchPath & )

Merges another search path into this one.

This will remove any duplicate directories.

◆ removeRedundantPaths()

void 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"

◆ removeNonExistentPaths()

void FileSearchPath::removeNonExistentPaths ( )

Removes any directories that don't actually exist.

◆ findChildFiles() [1/2]

Array< File > 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
whatToLookFora value from the File::TypesOfFileToFind enum, specifying whether to return files, directories, or both.
searchRecursivelywhether to recursively search the subdirectories too
wildCardPatterna pattern to match against the filenames
Returns
the number of files added to the array

File::findChildFiles

◆ findChildFiles() [2/2]

int 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.

◆ isFileInPath()

bool 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
fileToCheckthe file to look for
checkRecursivelyif 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.
