protected boolean supportsNonFileResources()

Overrides org.apache.tools.ant.taskdefs.Unpack.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.

Returns:boolean

true if this task supports non file resources.
