    public MultiRootFileSet()

- ## Method Details

  - ### setDir

    public void setDir(File dir)
    Description copied from class: `AbstractFileSet`
    Sets the base-directory for this instance.
    Overrides:
      `setDir` in class `AbstractFileSet`
    Parameters:
      `dir` - the directory's `File` instance.

  - ### setType

    public void setType(MultiRootFileSet.SetType type)
    Determines the types of resources to return.
    Parameters:
      `type` - the types of resources to return

  - ### setCache

    public void setCache(boolean b)
    Set whether to cache collections.
    Parameters:
      `b` - boolean cache flag.
