/**
 * This class handles the representation of a file on the filesystem within the framework.
 * Most of the methods also handle the {@link Folder} subclass.
 *
 * Note: The files are stored in the assets/ directory, but SilverStripe
 * looks at the db object to gather information about a file such as URL
 * It then uses this for all processing functions (like image manipulation).
 *
 * <b>Security</b>
 *
 * Caution: It is recommended to disable any script execution in the"assets/"
 * directory in the webserver configuration, to reduce the risk of exploits.
 * See http://doc.silverstripe.org/secure-development#filesystem
 *
 * <b>Asset storage</b>
 *
 * As asset storage is configured separately to any File DataObject records, this class
 * does not make any assumptions about how these records are saved. They could be on
 * a local filesystem, remote filesystem, or a virtual record container (such as in local memory).
 *
 * The File dataobject simply represents an externally facing view of shared resources
 * within this asset store.
 *
 * Internally individual files are referenced by a"Filename" parameter, which represents a File, extension,
 * and is optionally prefixed by a list of custom directories. This path is root-agnostic, so it does not
 * automatically have a direct url mapping (even to the site's base directory).
 *
 * Additionally, individual files may have several versions distinguished by sha1 hash,
 * of which a File DataObject can point to a single one. Files can also be distinguished by
 * variants, which may be resized images or format-shifted documents.
 *
 * <b>Properties</b>
 *
 * -"Title": Optional title of the file (for display purposes only).
 *   Defaults to"Name". Note that the Title field of Folder (subclass of File)
 *   is linked to Name, so Name and Title will always be the same.
 * -"File": Physical asset backing this DB record. This is a composite DB field with
 *   its own list of properties. {@see DBFile} for more information
 * -"Content": Typically unused, but handy for a textual representation of
 *   files, e.g. for fulltext indexing of PDF documents.
 * -"ParentID": Points to a {@link Folder} record. Should be in sync with
 *  "Filename". A ParentID=0 value points to the"assets/" folder, not the webroot.
 * -"ShowInSearch": True if this file is searchable
 *
 * @package framework
 * @subpackage filesystem
 *
 * @property string $Name Basename of the file
 * @property string $Title Title of the file
 * @property DBFile $File asset stored behind this File record
 * @property string $Content
 * @property string $ShowInSearch Boolean that indicates if file is shown in search. Doesn't apply to Folders
 * @property int $ParentID ID of parent File/Folder
 * @property int $OwnerID ID of Member who owns the file
 *
 * @method File Parent() Returns parent File
 * @method Member Owner() Returns Member object of file owner.
 *
 * @mixin Hierarchy
 * @mixin Versioned
