- ## Method Details

  - ### getDefaultExtension

    protected String getDefaultExtension()
    Get the default extension.
    Specified by:
      `getDefaultExtension` in class `Unpack`
    Returns:
      the value ".gz"

  - ### extract

    protected void extract()
    Implement the gunzipping.
    Specified by:
      `extract` in class `Unpack`

  - ### supportsNonFileResources

    protected boolean supportsNonFileResources()
    Whether this task can deal with non-file resources.

    This implementation returns true only if this task is <gunzip>. Any subclass of this class that also wants to support non-file resources needs to override this method. We need to do so for backwards compatibility reasons since we can't expect subclasses to support resources.

    Overrides:
      `supportsNonFileResources` in class `Unpack`
    Returns:
      true if this task supports non file resources.
