Class Base64

java.lang.Object
  org.apache.xmlbeans.impl.util.Base64

public final class Base64
extends java.lang.Object

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.
