Method Details

extract

protected void extract()
Do the unbzipping.
Overrides:
extract in interface Unpack

getDefaultExtension

protected String getDefaultExtension()
Get the default extension.
Overrides:
getDefaultExtension in interface Unpack
Returns:
the string ".bz2"

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 interface Unpack
Returns:
true if this class supports non file resources.
Since:
Ant 1.7
