Constructor Detail

GUnzip

public GUnzip()
Method Detail

getDefaultExtension

protected java.lang.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.
