IO Package

This package provides additional classes for input/output.

Contained are filter streams for Base64 encoding and decoding. Those filter streams can be plugged on top of another stream to encode/decode the data before reaching the underlying stream:

• de.ceyco.io.Base64DecoderInputStream A filter input stream that decodes data on the fly from BASE64 format as specified in the MIME specification.
• de.ceyco.io.Base64EncoderOutputStream A filter output stream that encodes data on the fly into BASE64 format as specified in the MIME specification.

It also contains two streams called StringBufferInputStream and StringBufferOutputStream. They fill a gap in Java's standard library, once filled by the class java.io.StringBufferInputStream. The original Java class is now deprecated, because it does not provide proper character encoding in translating characters into bytes. The two classes I developed do support character encoding.

• de.ceyco.io.StringBufferInputStream gets initialized using a regular String which then can be read from the stream using the specified character encoding.
• de.ceyco.io.StringBufferOutputStream on the other hand stores bytes written into it and provides them as a String.

Feel free to use them under the Lesser GPL.
