Package org.apache.xerces.impl.dv.util
Class Base64
java.lang.Object
org.apache.xerces.impl.dv.util.Base64
This class provides encode/decode for RFC 2045 Base64 as
defined by RFC 2045, N. Freed and N. Borenstein.
RFC 2045: Multipurpose Internet Mail Extensions (MIME)
Part One: Format of Internet Message Bodies. Reference
1996 Available at: http://www.ietf.org/rfc/rfc2045.txt
This class is used by XML Schema binary format validation
This implementation does not encode/decode streaming
data. You need the data that you will encode/decode
already on a byte arrray.
INTERNAL:
- Usage of this class is not supported. It may be altered or removed at any time.
