  - ### setSrc

    @Deprecated public void setSrc​(java.lang.String src)
    Deprecated.
    since 1.5.x. setSrc(String) is deprecated and is replaced with setSrc(File) to make Ant's Introspection mechanism do the work and also to encapsulate operations on the type in its own class.
    Parameters:
      `src` - a `String` value

  - ### setDest

    @Deprecated public void setDest​(java.lang.String dest)
    Deprecated.
    since 1.5.x. setDest(String) is deprecated and is replaced with setDest(File) to make Ant's Introspection mechanism do the work and also to encapsulate operations on the type in its own class.
    Parameters:
      `dest` - a `String` value

  - ### setSrc

    public void setSrc​(java.io.File src)
    The file to expand; required.
    Parameters:
      `src` - file to expand

  - ### setSrcResource

    public void setSrcResource​(Resource src)
    The resource to expand; required.
    Parameters:
      `src` - resource to expand

  - ### addConfigured

    public void addConfigured​(ResourceCollection a)

  - ### getDefaultExtension

    protected abstract java.lang.String getDefaultExtension()
