Examples of Base64OutputStream

com.ibm.commons.util.io.base64.Base64OutputStream
A Base64 content transfer encoding filter stream.
From RFC 2045, section 6.8:
The Base64 Content-Transfer-Encoding is designed to represent arbitrary sequences of octets in a form that need not be humanly readable. The encoding and decoding algorithms are simple, but the encoded data are consistently only about 33 percent larger than the unencoded data. @ibm-api

org.apache.james.mime4j.decoder.Base64OutputStream
This class has been copied from Apache MyFaces Trinidad 1.2.8 An OutputStream that encodes data in a base64 representation. It takes a Writer as its single argument to its constructor and all bytes written to the stream are correspondingly converted into Base64 and written out to the provided writer.
org.apache.myfaces.trinidad.util.Base64OutputStream
An OutputStream that encodes data in a base64 representation. It takes a Writer as its single argument to its constructor and all bytes written to the stream are correspondingly converted into Base64 and written out to the provided writer.
org.apache.tapestry5.internal.util.Base64OutputStream
An extension of {@link ByteArrayOutputStream} that allows the final byte array to be converted to a Base64 string.
