FileReference implements FileInterface

Representation of a specific usage of a file with possibilities to override certain properties of the original file just for this usage of the file.

It acts as a decorator over the original file in the way that most method calls are directly passed along to the original file object.

All file related methods are directly passed along; only meta data functionality is adopted in this decorator class to priorities possible overrides for the metadata for this specific usage of the file.

Various properties of the FileReference. Note that these information can be different to the ones found in the originalFile.
