          org.apache.geronimo.mail.util.QuotedPrintableDecoderStream

All Implemented Interfaces:

Closeable

public class QuotedPrintableDecoderStream
extends FilterInputStream

An implementation of a FilterOutputStream that decodes the stream data in Q-P 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.

Read a buffer of data from the input stream.

Overrides:

read in class FilterInputStream

Parameters:

buffer - The target byte array the data is placed into.

offset - The starting offset for the read data.

length - How much data is requested.

Returns:

The number of bytes of data read.

Throws:

IOException

markSupported

public boolean markSupported()

Indicate whether this stream supports the mark() operation.
