Class UniqueMediaPathScheme

Implements a unique directory media path scheme.

Inheritance

System.Object

Namespace: Umbraco.Cms.Core.IO.MediaPathSchemes

Assembly: Umbraco.Core.dll

Syntax

public class UniqueMediaPathScheme : IMediaPathScheme

Remarks

This scheme provides deterministic short paths, with potential collisions.

Methods

GetDeleteDirectory(MediaFileManager, String)

Gets the directory that can be deleted when the file is deleted.

Declaration

public string GetDeleteDirectory(MediaFileManager fileManager, string filepath)

Parameters

Type	Name	Description
MediaFileManager	fileManager
System.String	filepath	The filesystem-relative path of the file.

Returns

Type	Description
System.String	The filesystem-relative path of the directory.

Remarks

Returning null so that DeleteMediaFiles(IEnumerable<String>) does not delete any directory. This is because the above shortening of the Guid to 8 chars means we're increasing the risk of collision, and we don't want to delete files belonging to other media items.

And, at the moment, we cannot delete directory "only if it is empty" because of race conditions. We'd need to implement locks in MediaFileManager for this.

GetFilePath(MediaFileManager, Guid, Guid, String)

Gets a media file path.

Declaration

public string GetFilePath(MediaFileManager fileManager, Guid itemGuid, Guid propertyGuid, string filename)

Parameters

Type	Name	Description
MediaFileManager	fileManager	The media filesystem.
Guid	itemGuid	The (content, media) item unique identifier.
Guid	propertyGuid	The property type unique identifier.
System.String	filename	The file name.

Returns

Type	Description
System.String	The filesystem-relative complete file path.
