ProcessedFile extends AbstractFile

Representation of a specific processed version of a file. These are created by the FileProcessingService, which in turn uses helper classes for doing the actual file processing. See there for a detailed description.

Objects of this class may be freshly created during runtime or being fetched from the database. The latter indicates that the file has been processed earlier and was then cached.

Each processed file—besides belonging to one file—has been created for a certain task (context) and configuration. All these won't change during the lifetime of a processed file; the only thing that can change is the original file, or rather it's contents. In that case, the processed file has to be processed again. Detecting this is done via comparing the current SHA1 hash of the original file against the one it had at the time the file was processed. The configuration of a processed file indicates what should be done to the original file to create the processed version. This may include things like cropping, scaling, rotating, flipping or using some special magic. A file may also meet the expectations set in the configuration without any processing. In that case, the ProcessedFile object still exists, but there is no physical file directly linked to it. Instead, it then redirects most method calls to the original file object. The data of these objects are also stored in the database, to indicate that no processing is required. With such files, the identifier and name fields in the database are empty to show this.
