Package org.apache.commons.vfs2.util

Class URIBitSets

java.lang.Object
org.apache.commons.vfs2.util.URIBitSets
class URIBitSets extends Object
Internal URI encoding BitSet definitions.

This was forked from the BitSets in org.apache.commons.httpclient.URI, in order to not be dependent on HttpClient v3 API, when generating and handling GenericURLFileNames, but it should work with any different HTTP backend provider implementations.
