# class Base64EncoderBuf

Library: Foundation
Package: Streams
Header: Poco/Base64Encoder.h

## Description

This streambuf base64-encodes all data written to it and forwards it to a connected ostream.

Note: The characters are directly written to the ostream's streambuf, thus bypassing the ostream. The ostream's state is therefore not updated to match the buffer's state.
