Constructor Detail

### BUnzip2

    public BUnzip2()

Method Detail

### getDefaultExtension

    protected java.lang.String getDefaultExtension()

  Get the default extension.

  Specified by:
    `getDefaultExtension` in class `Unpack`
  Returns:
    the string ".bz2"

### extract

    protected void extract()

  Do the unbzipping.

  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 class supports non file resources.
