TYPO3 13.4 API: LocalDriver

LocalDriver extends AbstractHierarchicalFilesystemDriver implements StreamableDriverInterface

A concrete implementation for a File Driver for the local file system.

Interfaces

StreamableDriverInterface: An interface FAL drivers have to implement to fulfil the needs of streaming files using PSR-7 Response objects.

Methods

__construct() : mixed: Creates this object.
addFile() : non-empty-string: Adds a file from the local server's hard drive to a given path in TYPO3s storage location.
copyFileWithinStorage() : non-empty-string: Copies a file *within* the current storage.
copyFolderWithinStorage() : true: Folder equivalent to copyFileWithinStorage().

countFoldersInFolder() : int<0, max>: Returns the number of folders inside the specified path.
createFile() : non-empty-string: Creates a new (empty) file and returns the identifier.
createFolder() : non-empty-string: Creates a folder, within a given parent folder.
deleteFile() : bool: Removes a file from the filesystem. This does not check if the file is still used or if it is a bad idea to delete it for some other reason this has to be taken care of in the upper layers (e.g. the ResourceStorage).
deleteFolder() : bool: Removes a folder from the hard drive.
dumpFileContents() : void: Directly output the contents of the file to the output buffer.
fileExists() : bool: Checks if a file exists on the file system.

isCaseSensitiveFileSystem() : bool: Returns TRUE if this driver uses case-sensitive identifiers. NOTE: This is a configurable setting, but the setting does not change the way the underlying file system treats the identifiers; the setting should therefore always reflect the file system and not try to change its behaviour
isFolderEmpty() : bool: Checks if a folder contains files and (if supported) other folders.
