    public class DeleteFile
extends AbstractTransformer
    Deletes the file/directory (or files/directories) received on its input port if it matches the provided regular expression.
    In case of directories, deletion is performed recursively (if a directory matches, then the content gets deleted regardless whether it matches the regular expression or not).

       java.lang.String
       java.io.File
       java.lang.String[]
       java.io.File[]
    - generates:
       java.lang.String
       java.io.File
       java.lang.String[]
       java.io.File[]
