The parameter isIncremental of transform must be true.
If the transform is not in incremental mode, getChangedFiles will not contain any information (it will not contain the list of all the files with state NOTCHANGED.)
When a root level directory is removed, and incremental mode is on, the instance will receive a DirectoryInput instance for the removed folder, but getFile will return a directory that does not exist. In this case, the transform should prcess this as a removed input.
Returns the changed files. This is only valid if the transform is in incremental mode.
