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.
