Base64DecoderStream (Apache CXF JavaDoc 4.2.1 API)
Description: declaration: package: org.apache.cxf.attachment, class: Base64DecoderStream

Package org.apache.cxf.attachment

# Class Base64DecoderStream

java.lang.Object
java.io.InputStream
java.io.FilterInputStream
org.apache.cxf.attachment.Base64DecoderStream

All Implemented Interfaces:
  `Closeable`, `AutoCloseable`

public class Base64DecoderStream extends FilterInputStream
An implementation of a FilterInputStream that decodes the stream data in BASE64 encoding format. This version does the decoding "on the fly" rather than decoding a single block of data. Since this version is intended for use by the MimeUtilty class, it also handles line breaks in the encoded data.
