      Parameters:
        `from` - a string.

    - #### setTo

          public void setTo​(java.lang.String to)

      Sets the to part of the transformation rule.

        `setTo` in interface `FileNameMapper`
      Parameters:
        `to` - a string.

    - #### clear

          public void clear()

      Reset the list of files

    - #### addMappedName

          public void addMappedName​(java.lang.String mapping)

      Add a mapped name
      Parameters:
        `mapping` - the value to use.

    - #### mapFileName

          public java.lang.String[] mapFileName​(java.lang.String sourceFileName)

      Returns an array containing the target filename(s) for the given source file.

      if the given rule doesn't apply to the source file, implementation must return null. SourceFileScanner will then omit the source file in question.

        `mapFileName` in interface `FileNameMapper`
      Parameters:
        `sourceFileName` - the name of the source file relative to some given basedirectory.
      Returns:
        an array of strings if the rule applies to the source file, or null if it does not.
