Method Detail

extract

protected void extract()

Do the unbzipping.

Specified by:

extract in class Unpack

getDefaultExtension

protected String getDefaultExtension()

Get the default extension.

Specified by:

getDefaultExtension in class 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 class Unpack

Returns:

true if this class supports non file resources.

Since:

Ant 1.7
